At the age of 49, i started running and could only run two-tenths of a mile before losing my breath. In only one month, i was easily running three miles. The body's ability to improve is amazing.
Same. Most people can't run one lap around a track. I remember for me it was a big deal running 2 miles. Then eventually it went clear up to marathons. 5k was always my favorite distance
I was 52. I was taking an HIIT class where we did squats ALL OF THE TIME! I started ‘running for dummies’ and was amazed that I could run more than a block without thinking I was going to die. I was running 4 miles within 6 weeks. Not fast, but continuous.
I love this channel. At 48 I decided to get my crap together, cut way back on alcohol, eat right and exercise again. I’ve lost 32 lbs in 5 months. No pills, no crazy diet. Just taking care of my body. It can be done! 13 more pounds to go! Edit: 8 months in and now down 47. Setting whole new goals. Edit 2: weight is still off! Trying to shred an additional 10-12 to get LEAN for spring 2025!
@@rajatyadav5540 the family doesn't anything to do with it. You, and only you, have to precise while you're that you want your body to be given to science. And without a dead body, how the fuck a doctor is supposed to learn to pratice surgery?
I have extreme cardiophobia centering around the fear of heart attack/heart failure, and am therefore terrified of raising my heartrate. The feeling of my heart pumping throws me into panic attacks. This video and the comments have helped me feel more comfortable going to the gym. Understanding how the heart works brings me comfort. Thank you
The most recommended forms of cardio to build aerobic endurance and heart health is called zone 2 training. Around 60-70% of your max HR. One way to find this number is 180 - your age = Max HR you should aim for while training. Another way to determine this level of intensity if you don’t have a heart rate watch or strap is running/cardio at a “conversational pace” meaning you could hold a conversation with someone on the phone and they wouldn’t notice that you’re out of breath. Be sure to only breathe through your nose. For beginners, this can be achieved by just a brisk walk or an extremely slow jog. Even if 100% of your training is done at this “easy” intensity you will make massive improvements in heart health and physical performance while keeping risk of injury low. Only key is to stay consistent, trust the process. Follow a plan and slowly increase the time you spend training week over week. Hope this was helpful.
@@mickyJfan Thank you so much! It was helpful indeed. Would you say continuing at this brisk pace for a week, then increasing the intensity at 2 weeks is optimal? Or should I continue to increase the intensity only when my max HR is not being met at that intensity anymore? Hope this makes sense!
@@pinkcatgxrl I think you can try to train at a constant heart rate. For example if your goal is 140bpm, maybe at first that would be a 5km/h walk at 10% incline. if later you found that you can do this at 135bpm, you increase the speed or incline to 6km/h for example. if you can jog and maintain 140bpm you can start doing that. Basically your goal is heart rate not speed. but you'll improve your speed at the same heart rate
@@H0A0B123 Thank you for that! I went to the gym today and discovered that as of now, 6% incline at 2.5mph will keep my HR steady at my max of 160, an improvement from last week when it was a 4% incline at 2.5mph. I appreciate you confirming my question. Thank you so much for responding. Knowing more about how to train helps tremendously. And the more I do this, the more I become less afraid of the sensation.
I would love to see the differences between two cadavers where one was very physically active and the other wasn't. I've recently started building muscle through weight training and it's fascinating to me to see the muscles I've had my entire life growing and changing shape.
in school they disected an older man with a heart of 724g and a 4cm layer of fat around the kidneys. it is fascinating and really weird to see how much abuse a body can take.
There is a study where they compared the hearts of people who did only weight training (no cardio) and people who didn’t do any training. There wasn’t much noticeable difference in average. To have a stronger heart you can’t avoid cardio training.
@@AbhishekSingh-xq7yc yeah, the aortic and pulmonary valves are also called semilunar valves because of their shape, and speaking of shapes, the mitral valve is also known as bicuspid valve as it has two flaps.
You guys probably get a ton of comments and most likely won't see this, but if you do, could you potentially consider making a video about anxiety and depression in the brain and what's going on chemically or structurally from a mental health point of view? I've always been super curious and it would be cool to see the structures involved shown on the cadaver. Hopefully you guys see this and thanks for awesome videos!
Great question. Do neurotransmitter imbalances show up in the tissue? Research dirty genes like MTHFR, are known drivers of gut carnage that fubars your nuerotransmitter balance/production. Hello focus/attention issues and/or depression until it is fixed. Dirty genes is a great little book. ( holistic and functional med communities)
I think that's a complicated ask my man. There's chemical imbalance depression and also there's depression due to a shit life. Both are valid and real. But yeah ... I don't think there will be a real exact change in each depressed person. I've heard there's changes/ like atrophy...sortof. but I don't really know. I'm not a doctor or anything.
Hey Adam, you should check out this researcher Andrew Huberman, Hubermanlab, Stanford based researcher. Covers a lot of your queries in a scientifically sound but very accessible manner. He has made appearances on Joe Rogan and Lex Fridman podcasts.
I ran consitently for now 7 month, going from 6 km a week to 47 now and my HR at 4:45/km is the same as 5:30/km when I started. The heart can adapt if you train it well and you're consistent with your training. Keep it up everyone
I started running last year and I love it. Getting out there and getting your heart rate up for a prolonged period and a sweat going really wakes you up and makes you feel good.
I used to do drugs daily, then I became sober and later replaced those addictions with exercise. Exercise makes me feel energetic like I downed a strong cup of coffee, which is definitely better compared to the lethargy I would feel after using drugs
Started my journey at 294 lbs, incredibly weak on strength training and could barely do a 10 min brisk walk and my heartrate would be 150-160... after about a year, i was 235.2 lbs today, jogging for 20+ mins at a heartrate of 110-120, and im SIGNIFICANTLY stronger when weight training. It gets easier every time you do it, our bodies are incredibly powerful machines if you fuel and train them correctly.
What kind of training helped you most to lower your heart rate so dramatically? Did you focus more on HIIT, or more on intensities you could hold longer before getting out of breath?
Sounds similar to me I started at 270 at one point and just walking my heart rate would go as high as 160-170, resting heart rate in the 90s. Also my feet hurt REALLY bad after each walk and one foot got excruciating and I found out I had plantar fasciitis. After about a year I was down to 228 walking heart rate around 100-110 and resting heart rate in the 60s. I’m still dealing with the plantar fasciitis on and off for about 2 years now but it’s gotten much better.
Thanks for this amazing video. I always loved biology at school, and eventually became a personal trainer. One of my clients came to me with obesity and the inability to run more than a few metres without gasping for breath. After six months of good diet and a wide range of exercise (including lots of walking between our sessions), he had lost a lot of excess body fat and ran a 5K race. three months after that he ran a 10K. After another three months he ran a half-marathon. Fast forward, he has now run 4 marathons and loves exercise and healthy eating. The human body is amazing if you give it a chance.
I started dieting and excercising at 36. I was 105 kg. Now I'm 43, 80 kg. I lift weight I couldn't even imagine before, travel a distance on my bike - uphill - that I even can't dreamed of! Our hyper-adaptable body is a grace from God, don't waste it! Go excercise now, not tommorow!
@Mark Ryan, I thought you said you weighted 43,80 kg now, but later I understod that you was 43 years old and weighted 80kg 😅. Going from 105kg to 43kg would be a little unheathy I think 🤣.
I'm a french student, working in an environmental mouvement with a huge interest for the human body; and i don't know if i'll have enough time to learn everything i want to learn before dying. You guys make knowledge so light and attractive, and these are things that maybe we should all know about!! Thank you so much for sharing all this with us and, proof of my admiration, I send you a small heart from Canary islands
You are doing a great job by educating not only medical students but also non medical folks too.Thanks for these amazing videos and a great respect to body donors too.Thanks a lot.
This is such an amazing channel. I wish there wasn’t such a large focus on only the aesthetic effects of exercise. Knowing how it impacts all the systems of your body is inspiring. It motivates you to care for your body and stop thinking of exercise as a punishment.
Agreed! I couldn't give a fk what other people think my body looks like, I just care that I'm comfortable in my skin. But seeing how exercise can improve blood flow and increase capillaries around the body makes me want to nourish my cells! And learning how limited our myocardium is reeeeeeally puts preventative care into perspective 0_o I've started implementing weekly exercise goals and dug my fitbit out of my dresser to keep track of my bpm during exercise and my resting hr since stumbling across this channel 🙏🫀🧘🙇🏃
your body is a truly amazing piece of equipment, so we need to look after it. it never fails to amaze me how folk take their car to the garage for a service every 6-12 months, but neglect their bodies for decades.
Thanks Professor really informative lecture. I'm 65 and from age 18 to about 40 worked out three or more times weekly. Doing the same level of weight training and swimming got harder after 40. I swim most every other day now and gave up the weights to save my back and joints. I need the endorphins to stay healthy and happy. But I miss the endorphin rush I could get in my mid 20s after a 2 hour workout!! Age robs us of strength and the feel good level of benefits too. It sucks!! Enjoy your youth!💖
Im 66, running since I was 15. Survived 1 stress related heart attack only because of running. I live in Munich and work in UK, and have a treadmill in both apartments (dirt cheap if you buy on ebay), I run now at a pace that is 50% slower than in my mid 30s. It takes real effort to keep fit and if I skip a few days my fitness level plummets - I aim for 5 runs / 20km a week and am pretty good at keeping it. I do it for relaxation (engineering consultant workaholic, idiot that I am).. and to keep me alive. I have now got over watching others rocket past. I run for me and I hope to continue this great sport until the day I finally experience sleep. ☺
I only just started cardio training, been doing resistance for over a month, last week my bpm was 180 during high interval training down to 160 after 2 minutes at half resistance, this week I was at 170 and getting down to 150... in a week! I only do about 1.5 hours over the week but already it has been a huge improvement. I can't wait to see what happens in 6 months. This is a important lesson fro anyone just starting exercise... keep at it!
@@dingdong6005 Had a break over christmas that put me back, but still at it and stronger than ever, thanks for asking. I can now do a lot more cardio than ever before but it still has room for improvement.
What kind of training helped you most to lower your heart rate so dramatically? Did you focus more on HIIT, or more on intensities you could hold longer before getting out of breath?
As someone who has had open heart surgery and works out regularly, this video was great! Sometimes I will have that freak out moment when my heart rate goes up about if that is a good thing over time. This helps me set some of those fears aside that what I am doing is good for me. Not too much....not too little! Thanks!
I can see how people who don't move as much, can't get going right off the couch. I live in a senior community, and after watching this, and listening to their heart issues, I can see why we slow down as we age, and how things almost work against us when we don't keep moving (whether it be an injury, chronic illness or any other various things that can stop us from exercising) Thank you so much for this video, and happy holidays to everyone out there! 🙂
There are 4 valves which are: - Tricuspid valve (consists of 3 flaps) : this allows blood to pass from the right atrium to right ventricle but not in reverse direction - bicuspid valve aka mitral valve (consists of 2 flaps): allow blood to pass from left atrium to left ventricle but not in the reverse direction The other two are called semi lunar valves and they are: -pulmonary valve: and this allow blood to pass from right ventricle to pulmonary artery, but not in the reverse direction. -Aortic valve: allow blood to pass from left ventricle to aorta but not in the reserve direction
I watched this video about a year ago and was fascinated. It made me really want to go to the gym and push myself more in exercise. Thank you for this video and the information on the human body.
I started exercising two months ago. My bpm was usually around 80, now it's around 60 to 70 while resting or doing normal everyday stuff. It's interesting how much exercising impacts your whole body.
I had no idea heart cells could get bigger through exercise. I feel bad at myself quitting exercising through the quarantine. Really interesting videos, love them all!
Overexercise could also be bad for your health and your heart. 45 mins of intense workout I think is the recommended time of workout and two days of rest.
@@haroldcruz8550 maybe at the beginning but after a couple weeks you could easily start working out 6 days a week doin push/pull/legs split. Maybe you’re talking about Cardio? In which case you can definitely do more than 45 minutes a day as long as you slowly work up to it.
I just got in to nursing school (want to become a midwife) and after binge watching all your videos i feel more sure than ever that i want to dedicate my life to helping other humans (hopefully live ones though 🤭). These cadavers are blessings to us all to be able to learn in depth about our own bodies 🙏🏾
If possible, I would be very interested in seeing a side-by-side comparison of a sedentary heart with a highly athletic person's heart. Would be fascinating to the the physical differences between the both of them that accumulate over years/a lifetime of exercising
I'm 32 began running again only 2 weeks ago. Was only able to run 30 min straight on 5.7 before being depleted. Now I'm able to run 60 min straight. I can literally feel my heart and lungs utilizing the O2 more efficiently. I'm not as tired when I'm cooling down. And I recover my breathing quickly after. Loving the high of being healthy and active. And making my heart strong. Trying to hit 6.0 speed, that's my goal.
I just found your channel through this video. OMG, I want to see ALL your videos. You have taught me so much and inspired me to REALLY be consistent in my exercises. I am 60 years old and want to really become the best and healthiest I can be. Thank you for your videos.
I am in awe. Just thinking how exercise is strenghtening all the circulatory system around the whole body, how efficient it is routing more blood to some places and less to others... and this numbers of rest vs active in non trained person vs active in trained person, wow!!!!! Thank you guys, you deserve the best!
I am going to study this one in the next year. I am very excited to see all this live. Hope to get our lecturer to be of the same smooth attitude like this man. ❤️❤️❤️
My ex-wife is a surgical technician (we are still very close friends) and she would always tell me that I don't have a clue just how complex and wonderfully designed the human body is. She couldn't have been more correct. Since I accidentally ran across this channel about a month ago, I can't get enough of it. Well done, folks!
@@sirvaantguys like you dont deserve science. If you really very truly believe in science ,you cant believe in god and vice versa. Google this quote and understand the depth of this quote
I really and truly appreciate how you present these topics. I had a hard time staying engaged and passing my biology classes from Grade school all through uni. But this is so we'll paced and the practical demonstrations make it so easy to understand and enjoy. Kudos!
I just LOVE this kid, and I say that with big respect to your youthful appearance and exuberance. im 54 and exercise just working on my hilly acre lawn using a non-self-propelled mower. 💪🏼
In case no one has answered your little quiz: the 4 valves are aortic, mitral, pulmonary, and tricuspid. I have a congenital heart defect that was repaired at age 45. I'm now dealing with all 4 valves leaking. Just started walking for exercise.
@@allisond.46 No, more for overall cardiovascular health. Leaky heart valves can only be repaired or replaced via surgery (or minimally invasive trans catheter procedure). The leaks are mild to moderate and my doctor feels surgery is not warranted at this time.
I recently decided to get back into shape since during covid I got depressed and it’s so exciting to see this nonfiction come up! Great work as always!
Wow! That little organ sure packs a wallop! 😃 So cool - thank you! It’s very humbling to see how intricate our body systems are, and envision all the potential things that can go wrong with them. It makes me appreciate the fragility of life ❤️ The valves are: Tricuspid valve, Pulmonary valve, Mitral valve, Aortic valve.
I'm just starting a journey, quit smoking a year ago, gained weight. I have asthma, but I don't want to be trapped in this body anymore. Getting ready to start walking and getting a new job. Want to start working out at a gym slowly to build up breathing and strengthen my body. I just found out that my youngest son and his wife are expecting my first GRANDCHILD. I'm 57 and want to be here to see this child grow up. Motivation, is here finally. ❤❤
Amazing video! Its crazy how much the body can adapt with exercising. After 2 years of sedentary lifestyle over the pandemic lockdown period, my resting heart rate was over 100 bpm. Now I've been brisk walking on a treadmill for half an hour a day for the past 1 month and my heart rate is slowly coming back down.
That’s great ! Before quarantine I had a resting heart rate of 52 bpm, post quarantine its now up to 70. Started working out 5 times a week like before and its slowly going down as well
When I started cycling my resting heart rate was the most shocking and easily quantifiable metric on my progress. I went from a resting BPM of 70-80 (morbidly obese for many many years) to around 40-42, it's really amazing how drastically you can change and how fast your body adapts to a new lifestyle.
You are a genetic freak/ blessed person. For a lot of people 70 is a perfectly acceptable resting HR. 40 is very low even for well trained athletes. Marco Pantani who was juiced to the gills on EPO was still only 32. I have been doing cardio my whole life, never been overweight and rarely see below 48, at age 61 Well done for exercising.
@@marcdaniels9079 It's genetics as you said, on the other end of the spectrum my max HR is pretty low, I haven't done a Max HR test but judging from LTHR efforts my max HR shouldn't be more than 175, which is kinda low for my age (39), so probably my heart was genetically programmed to work 5-10 bpm lower to average.
I think you are the brightest person to teach these things. You so good and kind,or should I say you have a kind face while teaching. You have a passion for teaching anatomy and do it so well, no you , I love learning about it.
“No man has the right to be an amateur in the matter of physical training. It is a shame for a man to grow old without seeing the beauty and strength of which his body is capable.” ― Socrates
The four valves of the heart from right to left are as follows: 1. Tricuspid valve 2. Pulmonic valve 3. Mitral valve (or biscuspid, though this term is not often used) 4. Aortic valve - CMA, RN
ustedes son los mejores no me cansare nunca de decirlo estoy fascinado estudiando sus videos, aun con los subtitulos de youtube estan muy por encima de cualquier educación en cualquier universidad, muchas gracias de verdad miles de bendiciones para ustedes.
Muscle, Bone, Blood, and Heart functionality when exercising --> WoW!!! Thanks Man for unveiling these parts of my Physical Universe to my aware Consciousness. Grateful.
Started running in 2019, and now have a resting HR of 34! With that also came some additional issues- including the role that electrolytes play into the heart, as well as Atrial flutters in general which seem to be very common in endurance athletes. I'd love to see more of this type of thing!
@@theanatomylab couldnt the increase in muscle tissue limit the space for blood in the ventricle?So we need a balance between muscle and space? I kinda remember that i've seen this issue touched on this channel but not in this video.
@@intimpulliber7376 Im not a doctor, but from my understanding you're right. I guess thats why people suffering from high blood pressure for a long period of time got very big hearts, but still got a high risk of a heart attack.
After a surgery in thoracotomy I stopped working out for about 2 years and my heartrate increased to 85 to 100 bpm while resting causing me anxiety problems. When I started working out again the difference was crazy. After few months of consistent gym workouts and cardio my heartrate dropped down to 50/60 bpm while resting!
If there was anything that could convince me to exercise more, it was this video! I can see how it has a direct impact on your lifespan. If your heart has to pump at a higher bpm, that wears it out faster. On the other hand, if it's more efficient, it could save you a significant number of strokes over time! To me that correlates directly to a longer life 😮
A fascinating video . I am 58 and suffer from , COPD . Over the last four days i started to clear my overgrown garden . After day one i was exhausted with cramp and joint pain . Today , i spent four hours continuing the job . And don't feel too bad . Maybe another few days to complete the task , and if all goes well , maybe I shall attempt some cycling and swimming . I don't believe for one moment , that I will return to the fitness level of my service days , but anything is better than nothing . Thanks for your inspiration .
I remember some of Gunther von Hagen's series on the heart, particularly when he had aortas from people of different ages laid out on his examination table. The aortas became dramatically enlarged by age 50 due to cholesterol plaques. He was in his 60s and said that his aorta was like the 30 year old's because he ate a good diet, exercised, and had a few drinks a day. I wish I could find his series to watch again. I'm enjoying this series very much and I look forward to more informative vids!
I was born with tetralogy of Fallot so learning about the heart was always a thing for me. It’s awesome to see a real heart dissected and exposed. Thank you for doing this. ❤️
@@fighterinmkiwiscience3517 Tetralogy of Fallot is a combination of four birth defects of the heart. You're born with ventricular septal defect, pulmonary stenosis, a misplaced aorta and right ventricular hypertrophy.
I love this channel so much! It really helps me understand science even more then the ways teached in school books- And ofcourse, I appreciate your every moment of hardwork, the way you all work hard on bodies! Good luck for the future!
I'm 63. 1.) Great information 2.) Wish I had a professor explain things as simple and interesting like you when I took a physiology & anatomy class in college. I switched to business 🙂
I can't state enough how important it is to exercise and eat healthy throughout your life, don't wait till it's too late or later in life when it's much more difficult
I have been enjoying these videos a lot! It actually makes me less scared to have health issues understanding how everything works. Do you or will you make one about herniated discs in the back? There is a huge community out there struggling with bad backs myself included. I would love to see how it all works with pinched nerves and how parts of your body can go numb.
You guys are slaying it each time with these interesting and very relevant topics. Also holy crap, the aorta is huuuge. And here I thought the vein in front of our thighs that you guys showed in your other video was big enough already.
I'm Dutch originally, so I might have the valve names names slightly wrong but I believe it is as such: - Left: aortic valve ( left ventricle to aorta) & mitral valve (left atrium to left ventricle) - Right: pulmonic/pulmonary valve (right ventricle to artery) & tricuspid valve (right atrium to right ventricle)
I'd love to see, how a gastritis works and what it does to the body and why it happens. I love your videos and you guys tought me more than school in my 8 years of having school :)
After a little over a year of consistently lifting and cardio (6 days a week), my doctor was surprised to see a lower resting HR. He did an ECG and thankfully it’s all good news: my heart is healthier than before.
love these videos. The body is truly a stunning organism and some of the stuff it does automatically to keep our body operating is nothing short of amazing!
I'm a medical student im Germany so I only know the valve names in German / Latin, so I'll name them in German😂 The valve that connects the right atrium to the right ventricle would be called Valva tricuspidalis (as it has 3 cusps). The blood will then have to pass the Valva trunci pulmonalis (the valve that sends the blood to the lungs). The valve from the left atrium to the left ventricle would be called Valva mitralis or bicuspidalis as it has 2 cusps (This is also the valve that experiences the most stress which is why it is prone to infections like Endocarditis. Lastly the Valva aortae seperates the left ventricle from the rest of the body and is also responsible for collecting blood from the Aorta so that it can fill the coronary arteries to supply the blood. I hope this could help ^^
The anatomy of the human body is amazing. The information presented has helped refresh my knowledge base since my college days as a student in Exercise physiology.
Love this channel. I am a guy who understands mechanical things mostly heavy equipment engines and what not. This is so interesting to me because I see the body as a fine tuned machine in most cases. I have been into health and fitness my entire life. What I do not get is the unexplained of why and how in people I knew lived to their ripe old age that did not. For example I had a guy who did my welding on my excavator 15 or 20 years ago. Worry The Welder. He was raised in Kentucky. He stood 6 ft 5. His typical day when he was called out to my job site for welding: He would show up at 6:45 am drinking coffee and chain smoking his Paul Mal cigarette. He would be working at 7 am and at 9 am he would sit in his truck for a break and start in on a handle of whiskey. He would take a 15 minute break. He would be outside stick welding with his helmet on and I would see all the toxic fumes go in and around his helmet he was breathing it in. At this time he was about 70 years old. At noon back to his truck and right back to the handle of whiskey for a 1/2 hr break. He never slurred a word or stubble when walking. He would be back welding after break and would even have a cigarette under the helmet when welding puffing away. Then at 3 pm he was done for the day. he would sit in his truck for an hour finish his bottle off then drive home. The mans hands where huge. I got to talking to him one day because his life to me was so interesting. Big strong man I saw him lifting big heavy pieces of steel. I started asking questions. He was raised on a farm and worked his butt off as a kid. He started smoking Corn silk at 7 years old, then Chesterfield, Camels and then Paul Mals all not filtered. He learned welding in the Navy during WW2 or just after the end of the war. It was brought to my attention circa 5 years ago Worry was dead. He was in his 80s. I asked of what? Well he was mostly working outside his entire life and he ended up with melanoma from to much sun. How the hell did his body survive the abuse he put it through? I swear the man was made of Chromium steel himself.
I believe it has something to do with the way your body is built from birth. Stronger cells or something , the cleaning system has to be stronger in order for the body to clean all the mess you put into it. I have seen such people too
I know people from Serbia, my step father has friends, this guys drinks and smokes every day for years, they are so strong, and that is so impressive to me, my theory for this cases is: the genetics throught the years evolve because Hard winters or harsh conditions make humans more indestructible and strong 🤔
I have tenosynovitis... And would love to see you make a video about that so it's better explained to me and possibly others who may also have this issue. Love your videos. They helped me alot while going through paramedic school. Keep up the great work guys. Thanks
Wooowwww! This video is pure gold 💛! THANK YOUUUU! The human body is simply amazing! I am the kind of person that faints when I see blood and feel nausea when seeing injuries and stuff. I pushed myself through this video (though I cringed while you showed the body parts). But I am so happy I did that because now I know so many things about the heart ❤️. Thank you so much for this video, it is my first video I watch from you from start to finish and for sure it will not be the last one either 🥰
1. Eustachian and Thebesian Valve guarding the opening of Inferior Vena Cava and Coronary artery. 2. Tricuspid Valve between Right Atrium and Right Ventricle 3. Bicuspid Valve between Right Atrium and Right Ventricle 4. Pulmonary valve between Right Ventricle and Pulmonary Trunk 5. Aortic valve between Left ventricle and Systemic Aorta.
Thank you so much for starting to explain this!! I appreciate it as I asked for a video explaining what makes heart muscle different from other muscles cause in disease an enlarged heart is a bad thing so I feel like your getting their. You guys make this stuff so easy to understand😁
this channel has educated me more than my textbooks. topics that we care about, and highly well organized and presented; sometimes i feel like we dont deserve such high quality content like this. Edit: spelling mistake :P
My rest HR is always low, at 72 years it is about 42 bpm. In my thirties with long distance marathon training it reduced to 30 and for a while 28. I cycle instead of running since 2007, after first hip replacement, not due to running, but top of femur necrosis, and osteo. My max recorded HR in my thirties after short sprint reps was greater than 200, and these days, after 30 second sprints on my bike is 148 bpm One of my daughters has the same low rest heart rate at 40 years it is 42 bpm.
What kind of training helped you most to lower your heart rate so dramatically? Did you focus more on HIIT, Threshold, or more on intensities you could hold longer before getting out of breath?
Aortic valve, mitral valve, tricuspid valve, & pulmonic valve for the quiz! I wonder if you could get two cadavers with almost opposite lifestyles and health to see the difference in the importance of taking care of the body.🌻 Thank y'all for your time and energy! I am inspired!
I just love your channel!! I love the way you explain things and demonstrate them on the cadaver. Do you think you might ever do a video on how the heart ages over time? As an aging athlete, I’m particularly interested in how the performance of the heart changes as we age. As I’m in great shape, but overall performance is down from even 5 years ago, but I’m overall stronger than I was 10 yrs ago which is greatly due to improved nutrition. Anyway, thanks so much for your informative videos. Keep them coming!! 😊
I just started exercising regularly 6 months ago, with swimming, walking and lifting weights, after having been a couch potato my whole life, and I quite quickly noticed I was better able to relax when resting, and that I get less fatigued over all. Maybe that is because my heart is not as stressed out anymore. I also find it funny that there's sort of a running joke in the bodybuilding community (because so many skip out on cardio) that you shouldn't forget to exercise the most important muscle in your body: the heart.
At the age of 49, i started running and could only run two-tenths of a mile before losing my breath. In only one month, i was easily running three miles. The body's ability to improve is amazing.
Same. Most people can't run one lap around a track. I remember for me it was a big deal running 2 miles. Then eventually it went clear up to marathons. 5k was always my favorite distance
It's a beautiful thing man
I was 52. I was taking an HIIT class where we did squats ALL OF THE TIME! I started ‘running for dummies’ and was amazed that I could run more than a block without thinking I was going to die. I was running 4 miles within 6 weeks. Not fast, but continuous.
How much weight have you lost?
This is so so inspiring! i started running recently too and before I couldn’t run more than 10 minutes now I can go on an hour runs
I love this channel. At 48 I decided to get my crap together, cut way back on alcohol, eat right and exercise again. I’ve lost 32 lbs in 5 months. No pills, no crazy diet. Just taking care of my body.
It can be done!
13 more pounds to go!
Edit: 8 months in and now down 47. Setting whole new goals.
Edit 2: weight is still off! Trying to shred an additional 10-12 to get LEAN for spring 2025!

Can we just take a minute to be thankful for this vid and the person/family that donated the body for our learning benefit👍👍
Thank you!
organs in these videos r real, i had my doubts
It's really bad that family gives body they r making fun of dead
@@rajatyadav5540 that's just your opinion. Don't get further.
@@rajatyadav5540 the family doesn't anything to do with it. You, and only you, have to precise while you're that you want your body to be given to science.

Are you sure it was donated willingly?
I have extreme cardiophobia centering around the fear of heart attack/heart failure, and am therefore terrified of raising my heartrate. The feeling of my heart pumping throws me into panic attacks. This video and the comments have helped me feel more comfortable going to the gym. Understanding how the heart works brings me comfort. Thank you
The most recommended forms of cardio to build aerobic endurance and heart health is called zone 2 training. Around 60-70% of your max HR. One way to find this number is 180 - your age = Max HR you should aim for while training.
Another way to determine this level of intensity if you don’t have a heart rate watch or strap is running/cardio at a “conversational pace” meaning you could hold a conversation with someone on the phone and they wouldn’t notice that you’re out of breath. Be sure to only breathe through your nose. For beginners, this can be achieved by just a brisk walk or an extremely slow jog. Even if 100% of your training is done at this “easy” intensity you will make massive improvements in heart health and physical performance while keeping risk of injury low. Only key is to stay consistent, trust the process. Follow a plan and slowly increase the time you spend training week over week. Hope this was helpful.
@@mickyJfan Thank you so much! It was helpful indeed. Would you say continuing at this brisk pace for a week, then increasing the intensity at 2 weeks is optimal? Or should I continue to increase the intensity only when my max HR is not being met at that intensity anymore? Hope this makes sense!
@@pinkcatgxrl I think you can try to train at a constant heart rate. For example if your goal is 140bpm, maybe at first that would be a 5km/h walk at 10% incline. if later you found that you can do this at 135bpm, you increase the speed or incline to 6km/h for example. if you can jog and maintain 140bpm you can start doing that.
Basically your goal is heart rate not speed. but you'll improve your speed at the same heart rate
@@H0A0B123 Thank you for that! I went to the gym today and discovered that as of now, 6% incline at 2.5mph will keep my HR steady at my max of 160, an improvement from last week when it was a 4% incline at 2.5mph. I appreciate you confirming my question. Thank you so much for responding. Knowing more about how to train helps tremendously. And the more I do this, the more I become less afraid of the sensation.
@@pinkcatgxrl This makes me happy
I had open heart surgery at the age of 13,, pulmonic stenosis. I’m now 55 and workout everyday.. makes me feel alive!
I would love to see the differences between two cadavers where one was very physically active and the other wasn't. I've recently started building muscle through weight training and it's fascinating to me to see the muscles I've had my entire life growing and changing shape.
in school they disected an older man with a heart of 724g and a 4cm layer of fat around the kidneys. it is fascinating and really weird to see how much abuse a body can take.
There is a study where they compared the hearts of people who did only weight training (no cardio) and people who didn’t do any training. There wasn’t much noticeable difference in average. To have a stronger heart you can’t avoid cardio training.
How does it matter ? Both will be dead
Yes!!!

You guys probably get a ton of comments and most likely won't see this, but if you do, could you potentially consider making a video about anxiety and depression in the brain and what's going on chemically or structurally from a mental health point of view? I've always been super curious and it would be cool to see the structures involved shown on the cadaver. Hopefully you guys see this and thanks for awesome videos!
Yes! I hope they see your comment.
Great question. Do neurotransmitter imbalances show up in the tissue? Research dirty genes like MTHFR, are known drivers of gut carnage that fubars your nuerotransmitter balance/production. Hello focus/attention issues and/or depression until it is fixed. Dirty genes is a great little book. ( holistic and functional med communities)
Well, not even the best brain scientist have any idea how that works, so good luck with that.
I think that's a complicated ask my man. There's chemical imbalance depression and also there's depression due to a shit life. Both are valid and real. But yeah ... I don't think there will be a real exact change in each depressed person. I've heard there's changes/ like atrophy...sortof. but I don't really know. I'm not a doctor or anything.
Hey Adam, you should check out this researcher Andrew Huberman, Hubermanlab, Stanford based researcher. Covers a lot of your queries in a scientifically sound but very accessible manner. He has made appearances on Joe Rogan and Lex Fridman podcasts.
I ran consitently for now 7 month, going from 6 km a week to 47 now and my HR at 4:45/km is the same as 5:30/km when I started. The heart can adapt if you train it well and you're consistent with your training. Keep it up everyone
This guy's energy is everything! He looks like he's smiling when he's talking I love it!
I love this channel. I am not a medical student but I really like your ways of explaining the human body.

Even though we did anatomy in 1st and 2nd year at uni.
Doanna I'm an OT student! :-)
I started running last year and I love it. Getting out there and getting your heart rate up for a prolonged period and a sweat going really wakes you up and makes you feel good.
Totally agree!
I used to do drugs daily, then I became sober and later replaced those addictions with exercise.
Exercise makes me feel energetic like I downed a strong cup of coffee, which is definitely better compared to the lethargy I would feel after using drugs
@@owmystomach8403 well done! That takes alot of self discipline
@@owmystomach8403 same exact thing for me, only got sober at 32. Im 35 and have never felt better emotionally and physically.
True ‼️
Started my journey at 294 lbs, incredibly weak on strength training and could barely do a 10 min brisk walk and my heartrate would be 150-160... after about a year, i was 235.2 lbs today, jogging for 20+ mins at a heartrate of 110-120, and im SIGNIFICANTLY stronger when weight training. It gets easier every time you do it, our bodies are incredibly powerful machines if you fuel and train them correctly.
What kind of training helped you most to lower your heart rate so dramatically?
Did you focus more on HIIT, or more on intensities you could hold longer before getting out of breath?
Sounds similar to me I started at 270 at one point and just walking my heart rate would go as high as 160-170, resting heart rate in the 90s. Also my feet hurt REALLY bad after each walk and one foot got excruciating and I found out I had plantar fasciitis. After about a year I was down to 228 walking heart rate around 100-110 and resting heart rate in the 60s. I’m still dealing with the plantar fasciitis on and off for about 2 years now but it’s gotten much better.
Thanks. I needed to hear that
Fantastic news
Thanks for this amazing video. I always loved biology at school, and eventually became a personal trainer. One of my clients came to me with obesity and the inability to run more than a few metres without gasping for breath. After six months of good diet and a wide range of exercise (including lots of walking between our sessions), he had lost a lot of excess body fat and ran a 5K race. three months after that he ran a 10K. After another three months he ran a half-marathon. Fast forward, he has now run 4 marathons and loves exercise and healthy eating. The human body is amazing if you give it a chance.
I started dieting and excercising at 36. I was 105 kg. Now I'm 43, 80 kg. I lift weight I couldn't even imagine before, travel a distance on my bike - uphill - that I even can't dreamed of! Our hyper-adaptable body is a grace from God, don't waste it! Go excercise now, not tommorow!

I am an introvert addicted to exercising, I can not lie...I always feel so good I can't explain.
This is such an amazing channel. I wish there wasn’t such a large focus on only the aesthetic effects of exercise. Knowing how it impacts all the systems of your body is inspiring. It motivates you to care for your body and stop thinking of exercise as a punishment.
I dont consider it punishment, but you need to set aside time for it. Also, cardio exercises are BORING!
Agreed! I couldn't give a fk what other people think my body looks like, I just care that I'm comfortable in my skin. But seeing how exercise can improve blood flow and increase capillaries around the body makes me want to nourish my cells! And learning how limited our myocardium is reeeeeeally puts preventative care into perspective 0_o I've started implementing weekly exercise goals and dug my fitbit out of my dresser to keep track of my bpm during exercise and my resting hr since stumbling across this channel 🙏🫀🧘🙇🏃

Thanks Professor really informative lecture. I'm 65 and from age 18 to about 40 worked out three or more times weekly. Doing the same level of weight training and swimming got harder after 40. I swim most every other day now and gave up the weights to save my back and joints. I need the endorphins to stay healthy and happy. But I miss the endorphin rush I could get in my mid 20s after a 2 hour workout!! Age robs us of strength and the feel good level of benefits too. It sucks!! Enjoy your youth!💖
Who is enjoying their youth? Have you seen the state of today's youth? It's tragic!
@Cornerdisc5504 there's some truth to that, but I meant the moral fabric is destroyed. I wasn't talking about bills
Im 66, running since I was 15. Survived 1 stress related heart attack only because of running. I live in Munich and work in UK, and have a treadmill in both apartments (dirt cheap if you buy on ebay), I run now at a pace that is 50% slower than in my mid 30s. It takes real effort to keep fit and if I skip a few days my fitness level plummets - I aim for 5 runs / 20km a week and am pretty good at keeping it. I do it for relaxation (engineering consultant workaholic, idiot that I am).. and to keep me alive. I have now got over watching others rocket past. I run for me and I hope to continue this great sport until the day I finally experience sleep. ☺
Sarcopenia will only get worse if you do no resistance training.
Get some hormone replacement therapy and hit the weights again. Carefully. Focus 100% on proper nutrition. Get an ebike and start biking.
I only just started cardio training, been doing resistance for over a month, last week my bpm was 180 during high interval training down to 160 after 2 minutes at half resistance, this week I was at 170 and getting down to 150... in a week! I only do about 1.5 hours over the week but already it has been a huge improvement. I can't wait to see what happens in 6 months. This is a important lesson fro anyone just starting exercise... keep at it!
How are you doing now?
@@dingdong6005 Had a break over christmas that put me back, but still at it and stronger than ever, thanks for asking. I can now do a lot more cardio than ever before but it still has room for improvement.

As someone who has had open heart surgery and works out regularly, this video was great! Sometimes I will have that freak out moment when my heart rate goes up about if that is a good thing over time. This helps me set some of those fears aside that what I am doing is good for me. Not too much....not too little! Thanks!
hi, what kind of exercise you do?
I can see how people who don't move as much, can't get going right off the couch. I live in a senior community, and after watching this, and listening to their heart issues, I can see why we slow down as we age, and how things almost work against us when we don't keep moving (whether it be an injury, chronic illness or any other various things that can stop us from exercising)
Thank you so much for this video, and happy holidays to everyone out there! 🙂
There are 4 valves which are:
- Tricuspid valve (consists of 3 flaps) : this allows blood to pass from the right atrium to right ventricle but not in reverse direction
- bicuspid valve aka mitral valve (consists of 2 flaps): allow blood to pass from left atrium to left ventricle but not in the reverse direction
The other two are called semi lunar valves and they are:
-pulmonary valve: and this allow blood to pass from right ventricle to pulmonary artery, but not in the reverse direction.
-Aortic valve: allow blood to pass from left ventricle to aorta but not in the reserve direction
Great!
@@theanatomylab pin him

I started exercising two months ago. My bpm was usually around 80, now it's around 60 to 70 while resting or doing normal everyday stuff. It's interesting how much exercising impacts your whole body.
I had no idea heart cells could get bigger through exercise. I feel bad at myself quitting exercising through the quarantine. Really interesting videos, love them all!
Never too late to jump back in
Overexercise could also be bad for your health and your heart. 45 mins of intense workout I think is the recommended time of workout and two days of rest.

@@haroldcruz8550 maybe at the beginning but after a couple weeks you could easily start working out 6 days a week doin push/pull/legs split. Maybe you’re talking about Cardio? In which case you can definitely do more than 45 minutes a day as long as you slowly work up to it.

As a Cardiothoracic surgery medical coder, this is so fascinating to actually see the heart/full picture of all the terms I work with each day ❤
If possible, I would be very interested in seeing a side-by-side comparison of a sedentary heart with a highly athletic person's heart. Would be fascinating to the the physical differences between the both of them that accumulate over years/a lifetime of exercising
I'm 32 began running again only 2 weeks ago. Was only able to run 30 min straight on 5.7 before being depleted. Now I'm able to run 60 min straight. I can literally feel my heart and lungs utilizing the O2 more efficiently. I'm not as tired when I'm cooling down. And I recover my breathing quickly after. Loving the high of being healthy and active. And making my heart strong. Trying to hit 6.0 speed, that's my goal.
That's pretty incredible. You're probably running a 10 minute mile. So, 3 miles in 2 weeks? Wow.
How are you doing now?
Exercise reduces stress hormones that can put an extra burden on the heart👍

Are you hoping it’ll help with the leaks?
@@allisond.46 No, more for overall cardiovascular health. Leaky heart valves can only be repaired or replaced via surgery (or minimally invasive trans catheter procedure). The leaks are mild to moderate and my doctor feels surgery is not warranted at this time.

After a surgery in thoracotomy I stopped working out for about 2 years and my heartrate increased to 85 to 100 bpm while resting causing me anxiety problems.
When I started working out again the difference was crazy. After few months of consistent gym workouts and cardio my heartrate dropped down to 50/60 bpm while resting!
Thanks for sharing
How are you doing now?
If there was anything that could convince me to exercise more, it was this video! I can see how it has a direct impact on your lifespan. If your heart has to pump at a higher bpm, that wears it out faster. On the other hand, if it's more efficient, it could save you a significant number of strokes over time! To me that correlates directly to a longer life 😮
A fascinating video . I am 58 and suffer from , COPD . Over the last four days i started to clear my overgrown garden . After day one i was exhausted with cramp and joint pain . Today , i spent four hours continuing the job . And don't feel too bad . Maybe another few days to complete the task , and if all goes well , maybe I shall attempt some cycling and swimming . I don't believe for one moment , that I will return to the fitness level of my service days , but anything is better than nothing . Thanks for your inspiration .
I remember some of Gunther von Hagen's series on the heart, particularly when he had aortas from people of different ages laid out on his examination table. The aortas became dramatically enlarged by age 50 due to cholesterol plaques. He was in his 60s and said that his aorta was like the 30 year old's because he ate a good diet, exercised, and had a few drinks a day. I wish I could find his series to watch again.
I'm enjoying this series very much and I look forward to more informative vids!

@@fighterinmkiwiscience3517 Tetralogy of Fallot is a combination of four birth defects of the heart. You're born with ventricular septal defect, pulmonary stenosis, a misplaced aorta and right ventricular hypertrophy.
I love this channel so much! It really helps me understand science even more then the ways teached in school books- And ofcourse, I appreciate your every moment of hardwork, the way you all work hard on bodies! Good luck for the future!
Thank you!
Agreed. Much better than any school, undergrad or med school.
Yes!! This video came during the time I'm studying for my exam about the cardiovascular system! 🙏🏽
Thank you, as always!!
I'm 63. 1.) Great information 2.) Wish I had a professor explain things as simple and interesting like you when I took a physiology & anatomy class in college. I switched to business 🙂
I can't state enough how important it is to exercise and eat healthy throughout your life, don't wait till it's too late or later in life when it's much more difficult
I have been enjoying these videos a lot! It actually makes me less scared to have health issues understanding how everything works. Do you or will you make one about herniated discs in the back? There is a huge community out there struggling with bad backs myself included. I would love to see how it all works with pinched nerves and how parts of your body can go numb.
You guys are slaying it each time with these interesting and very relevant topics.
Also holy crap, the aorta is huuuge. And here I thought the vein in front of our thighs that you guys showed in your other video was big enough already.
Thank you! And yes, the aorta is huge!
Umm... I'd totally want to watch a 40 minute video on muscle adaptation.
Thank you for all that you offer us. Happy Holidays from Canada!
Satisfied after watching this video as I am a regular runner and in mid 26... This video will motivate me to push myself forward...👍
I love these clear explainations for non medical people to understand how the heart functions. You are a top professor !
I'm a student of class XI. This channel makes biology so easy for me to understand.🖤🖤
Glad to hear it!
Same here but I am in class X.. 😀
I'm Dutch originally, so I might have the valve names names slightly wrong but I believe it is as such:
- Left: aortic valve ( left ventricle to aorta) & mitral valve (left atrium to left ventricle)
- Right: pulmonic/pulmonary valve (right ventricle to artery) & tricuspid valve (right atrium to right ventricle)
I'd love to see, how a gastritis works and what it does to the body and why it happens. I love your videos and you guys tought me more than school in my 8 years of having school :)
After a little over a year of consistently lifting and cardio (6 days a week), my doctor was surprised to see a lower resting HR. He did an ECG and thankfully it’s all good news: my heart is healthier than before.
Proud of you
How fearfully and wonderfully made are we by God🙌🏽
Thanks for this presentation !
love these videos. The body is truly a stunning organism and some of the stuff it does automatically to keep our body operating is nothing short of amazing!
I'm a medical student im Germany so I only know the valve names in German / Latin, so I'll name them in German😂
The valve that connects the right atrium to the right ventricle would be called Valva tricuspidalis (as it has 3 cusps). The blood will then have to pass the Valva trunci pulmonalis (the valve that sends the blood to the lungs).
The valve from the left atrium to the left ventricle would be called Valva mitralis or bicuspidalis as it has 2 cusps (This is also the valve that experiences the most stress which is why it is prone to infections like Endocarditis.
Lastly the Valva aortae seperates the left ventricle from the rest of the body and is also responsible for collecting blood from the Aorta so that it can fill the coronary arteries to supply the blood.
I hope this could help ^^

The anatomy of the human body is amazing. The information presented has helped refresh my knowledge base since my college days as a student in Exercise physiology.
This kind of content keeps me engaged with UA-cam . Plenty of knowledge
Those 4 valves: Aortic, pulmonary, tricuspid and mitral. Thank you as always for such informative videos. You guys are the best.
What a timing I was thinking today about heart and how exercising helps it and wala! A video which has both.
Perfect!
Love this channel. I am a guy who understands mechanical things mostly heavy equipment engines and what not. This is so interesting to me because I see the body as a fine tuned machine in most cases. I have been into health and fitness my entire life. What I do not get is the unexplained of why and how in people I knew lived to their ripe old age that did not. For example I had a guy who did my welding on my excavator 15 or 20 years ago. Worry The Welder. He was raised in Kentucky. He stood 6 ft 5. His typical day when he was called out to my job site for welding: He would show up at 6:45 am drinking coffee and chain smoking his Paul Mal cigarette. He would be working at 7 am and at 9 am he would sit in his truck for a break and start in on a handle of whiskey. He would take a 15 minute break. He would be outside stick welding with his helmet on and I would see all the toxic fumes go in and around his helmet he was breathing it in. At this time he was about 70 years old. At noon back to his truck and right back to the handle of whiskey for a 1/2 hr break. He never slurred a word or stubble when walking. He would be back welding after break and would even have a cigarette under the helmet when welding puffing away. Then at 3 pm he was done for the day. he would sit in his truck for an hour finish his bottle off then drive home. The mans hands where huge. I got to talking to him one day because his life to me was so interesting. Big strong man I saw him lifting big heavy pieces of steel. I started asking questions. He was raised on a farm and worked his butt off as a kid. He started smoking Corn silk at 7 years old, then Chesterfield, Camels and then Paul Mals all not filtered. He learned welding in the Navy during WW2 or just after the end of the war. It was brought to my attention circa 5 years ago Worry was dead. He was in his 80s. I asked of what? Well he was mostly working outside his entire life and he ended up with melanoma from to much sun. How the hell did his body survive the abuse he put it through? I swear the man was made of Chromium steel himself.
I believe it has something to do with the way your body is built from birth. Stronger cells or something , the cleaning system has to be stronger in order for the body to clean all the mess you put into it. I have seen such people too
I know people from Serbia, my step father has friends, this guys drinks and smokes every day for years, they are so strong, and that is so impressive to me, my theory for this cases is: the genetics throught the years evolve because Hard winters or harsh conditions make humans more indestructible and strong 🤔
I have tenosynovitis... And would love to see you make a video about that so it's better explained to me and possibly others who may also have this issue. Love your videos. They helped me alot while going through paramedic school. Keep up the great work guys. Thanks
Wooowwww! This video is pure gold 💛! THANK YOUUUU! The human body is simply amazing!
I am the kind of person that faints when I see blood and feel nausea when seeing injuries and stuff. I pushed myself through this video (though I cringed while you showed the body parts). But I am so happy I did that because now I know so many things about the heart ❤️.
Thank you so much for this video, it is my first video I watch from you from start to finish and for sure it will not be the last one either 🥰
1. Eustachian and Thebesian Valve guarding the opening of Inferior Vena Cava and Coronary artery.
2. Tricuspid Valve between Right Atrium and Right Ventricle
3. Bicuspid Valve between Right Atrium and Right Ventricle
4. Pulmonary valve between Right Ventricle and Pulmonary Trunk
5. Aortic valve between Left ventricle and Systemic Aorta.
Thank you so much for starting to explain this!! I appreciate it as I asked for a video explaining what makes heart muscle different from other muscles cause in disease an enlarged heart is a bad thing so I feel like your getting their. You guys make this stuff so easy to understand😁
this channel has educated me more than my textbooks. topics that we care about, and highly well organized and presented; sometimes i feel like we dont deserve such high quality content like this.
Edit: spelling mistake :P
My rest HR is always low, at 72 years it is about 42 bpm. In my thirties with long distance marathon training it reduced to 30 and for a while 28. I cycle instead of running since 2007, after first hip replacement, not due to running, but top of femur necrosis, and osteo. My max recorded HR in my thirties after short sprint reps was greater than 200, and these days, after 30 second sprints on my bike is 148 bpm One of my daughters has the same low rest heart rate at 40 years it is 42 bpm.
What kind of training helped you most to lower your heart rate so dramatically?
Did you focus more on HIIT, Threshold, or more on intensities you could hold longer before getting out of breath?
I have learned tremendously from this video. I understand my heart more now then ever. My adult grandkids are learning about the heart in high school.
Aortic valve, mitral valve, tricuspid valve, & pulmonic valve for the quiz!
I wonder if you could get two cadavers with almost opposite lifestyles and health to see the difference in the importance of taking care of the body.🌻
Thank y'all for your time and energy! I am inspired!
I just love your channel!! I love the way you explain things and demonstrate them on the cadaver. Do you think you might ever do a video on how the heart ages over time? As an aging athlete, I’m particularly interested in how the performance of the heart changes as we age. As I’m in great shape, but overall performance is down from even 5 years ago, but I’m overall stronger than I was 10 yrs ago which is greatly due to improved nutrition. Anyway, thanks so much for your informative videos. Keep them coming!! 😊
I'm a bio student , and these are super helpful videos , keep up the good work :)
Thank you! Will do!
I just started exercising regularly 6 months ago, with swimming, walking and lifting weights, after having been a couch potato my whole life, and I quite quickly noticed I was better able to relax when resting, and that I get less fatigued over all. Maybe that is because my heart is not as stressed out anymore. I also find it funny that there's sort of a running joke in the bodybuilding community (because so many skip out on cardio) that you shouldn't forget to exercise the most important muscle in your body: the heart.
I appreciate your positive message and wish you happiness and fulfillment in your life, young man.
Love watching his videos, im not a student or into medicine just love how he makes it interesting and fun
Thank you!
