I remember watching this a couple of years ago for the first time when going through A&P 1, trying for the life of me to remember how the circulatory system worked. Fast forward to now, I'm currently a semester 1 nursing student about to head to my first clinical in a little more than a week. It's crazy how time flew by but I'll always make time for a crashcourse refresher
I do not procrastinate! My class just started this section today. I watch CrashCourse first, get a general overview, then go into more and more detail. CrashCourse is not just for students who didn't study, it is also for people who are studying.
CrashCourse Isthere any danger to having two hearts? Because if I had the money I would have an artificial heart installed in my body alongside my normal one, exactly for this reason, vulnerability.
zoranhacker Humans are surprisingly very tender and can die from just a small part of the body going out of whack. The amazing thing is how our bodies naturally regulate themselves so well that we are able to live. Really, I think the more you watch this series, the more you will feel like, "Way to go, body! Way to go."
zoranhacker Don't, the hearts been evolutionarily tested for millions of years and typically the "bad hearts" would fail before the Human could procreate, so the odds of you having a gene that causes heart failure at a young age is all but gone. But your lifestyle will affect its performance down the road, so take care of yourself bud.. I didn't, I don't have a heart condition just yet but i'm sure I will and its not a good feeling to be worried about your ticker.
sacr3 I'm aware of the level of perfection that our bodies are, and I didn't say I was reasonably feeling vulnerable, I just was. And why are you so sure you will have a heart condition? Whatever it is that's bad about your lifestyle can change if you want it to, which I don't see why you wouldn't if the other option is getting a heart condition.
im a nursing student, and i paid 89$ for this online course for learning anatomy & physiology but your videos often give me a better, more overall understanding!
Heartbreaking is real.. your heart has it's own brain cells aswell.. Aztecs, Egyptians and many more ancient cultures knew this but modern western doesn't approve that but more and more were finding that the heart has more powers.. the most important thing to know is that God check ones heart when we die so keep it pure🙏
As someone who's had heart problems her whole life, this made more sense than anything doctors have attempted to explain to me, so thanks for that! Really helpful :)
How to break a heart (let it go) The heart on call 24 hours a day. It is work all throughout the night. If it sounds like walking on cold snow. We will rush you to the ER. It's building pressure up inside. Gonna let go, through the atrial valve. Don't eat that cake. Eat healthy food. Go to the gym and skip the chips instead produce. Otherwise you heart is screwd! Let it be. It will beat Even if you don't think of it. It is your true love. Whiteout it you would be dead now! It dosent care about what your crush just said. Its only job is keeping you alive. Hey Hank I expect you to sing this on at least one of you channels. This video gave me goosebumps. Guess I made the right choice to be an MD! Love heart sounds.
I'm a medical student and have a pretty strong stomach for most things but for some reason I just hate hearts - to the point where I've passed out dissecting one. It seems so irrational considering the importance of our and the fact that other organs are absolutely fine for me, but the thought of hearts or the just hearing the sound they make makes me freak out. Great since I'm going to be a doctor, amirite? Loving the anatomy series, helps me recap things I've learned and is funny and interesting. Wish I had these videos back when I was doing my A level biology.
And this is why I love you! My pharm students start drugs for angina and heart failure tomorrow, and then I'll have them watch this, and then we'll do hypertension next week. You folks save me valuable class time (and time I would spend making my sad little videos) that I can now use for active learning and case studies. Thank you, thank you! I do also like that you include little shout outs to pathophysiology like the effects of long term hypertension and congestive heart failure. It makes learning the A & P so seem much more relevant to students starting out in the health sciences!

Dear John, I've been graduated from high school for 5 years now (god it's been so much longer than it feels), and I recently was reminded by you that it was you in crash course all those years ago. I downloaded all of them and am now listening through it during work, learning is fun when you're not being forced to.
i passed my anatomy class becuz of these videos from crash coarse, thank you for making crash coarse available and free .. i love your voice btw and your fun personality. from NORTHDAKOTA
whenever im listening to this guy, i always feel the need to take a minute to catch my breath even tho i dont need to, hes just talking so fast it feels like hes not breathing lmao
My mum actually did this to her mother, and heard a gush when you should hear a thud. She was later diagnosed with a leaking mitral bicusbid valve which required surgery and implantation of a pig heart valve. Had my mum not done this, it is quite possible that my grandmother would have died years earlier.
Used to do this a lot to my parents when I was little. Just lying on them listening to the heartbeats. It's a shame we grow up and don't get this type of intimacy any more. I'll need to put my ear against my boyfriend's chest next time he comes.
Hi Crash Course! We've translated this episode's Chinese subtitles! Hope you can take a look and allow it to be displayed. Nerdfighters, let's make Crash Course more friendly to every learner :D DFTBA! P.S. last time we translated subtitles, they were never put up, so we really hesitated to try again since it took lots of effort and time:( let's hope they are not so busy this time :(
A thank you to Crashcourse on behalf of parents! I have been showing my kids your videos for years, and now my oldest is in middle school and participates in all sorts of STEM activities without any direct pressure from me. I’m now showing your videos to my kindergartner, and will be doing so for years to come. Thank you again, and happy holidays.
Courtesy of ChatGPT: (Verse 1) I had a broken heart, I thought it was love But it was just my blood pressure rising up above I thought I'd never mend, I thought I'd never thrive But then I learned to manage, and now I'm feeling alive (Chorus) I've got a broken heart, but it's not from love It's from high blood pressure, from stress and stuff I take my meds and I watch what I eat Now my heart is mended, and I'm feeling fleet (Verse 2) I used to worry all the time, my stress was through the roof But now I take it easy, I've learned to be aloof I exercise and I eat my greens And now my heart is healthy, and my blood pressure clean (Chorus) I've got a broken heart, but it's not from love It's from high blood pressure, from stress and stuff I take my meds and I watch what I eat Now my heart is mended, and I'm feeling fleet (Bridge) Don't let high blood pressure bring you down There are ways to manage it, don't let it get you down Take care of your heart, and it will take care of you You'll be feeling healthy, and your heart will be brand new (Chorus) I've got a broken heart, but it's not from love It's from high blood pressure, from stress and stuff I take my meds and I watch what I eat Now my heart is mended, and I'm feeling fleet
I hope Hank sees this! What's the Point? My heart, your heart... they all look alike, two puffy mounds at the top, tapering down into a spike. But just why is it that they all look the same? Shouldn't a person's heart be as individual as his name? Well, if you look a bit closer you will readily see that everyone's heart is just as different as he (or she!). For it's not the shape, nor even the size, But what's inside that is truly the prize. The mound on the right... holds memories so dear only the good ones from year after year. And the mound on the left, is filled to the brim with the light of sweet passion, that never grows dim. Now the part in the middle, is where deep love resides. Its strength can be fierce, Yet here, too, fragility hides. Then finally, slowly, the heart slopes to a fine edge.. coming to a sharp point in the shape of a wedge. This point is for balance between all the parts which is very important for those with full hearts! And if you look more closely you will see right at the tip a tiny little hole no bigger than a pin. This is the place where all our sorrows go They stay with us a short while, then seep out with the flow. Hearts can be lonely, Hearts can be sad... Hearts can be faithful, In good times and bad But no matter the shape, Nor how big or how small, Your heart is a gift, To be shared with all.
quick tip for ya'll who have a hard time watching it cuz he's going to fast: change the speed in the video to 0.75 and he's actually talking at the speed of a normal human. Really helped me out
I'm a Physiology PhD with a CV exam tomorrow and the most valuable 10 minutes of my studying has been watching this video. Even material that goes into in-depth biophysics and abstract concepts is given great context by this refresher. High schoolers and medical students alike should watch this when preparing for any cardiovascular exam.
thankyou guys for the all the work...its really really helping me and my friends to study without getting bored.if any of us have any dought in histology and anatomy we clarify it through your videos...thanks a lottt for your help..and keep it up with it....
I learn so much from these crash courses. Lectures at my school are too short and boring. This crash course I watch with such enthusiasm. Just love it. Thank you for making A&P easy to learn
Crash course,, Wow! As senior clinician i have been really encouraged by your lectures. I feel know i have to contirbute my fair share to the world of Medical Science. Thus, I have uploaded my first PPT based video.
I am currently a nationally certified EMT and felt I needed to brush up on my cardiac knowledge. This video was very helpful and your personality kept me interested (: Thank you!
KindessisEternal I've a condition which messes with my valves, and the right side of my heart. I like to think I have a reasonable grasp of how hearts generally work (and the particular way that mine doesn't work so well) and I enjoyed watching a video which explained things so clearly. I'm hoping from the title of the next video that it might talk more about the beating of the heart. I'm interested in the way that the heart's natural pacemaker works, and the way that my pacemaker replaces that function when it goes awry.
TheFireflyGrave The diagram in my science textbook in primary school had the veins in blue and the arteries in red to make is clear enough to see the difference,
I'm studying to become a teacher (biology and English)... but I'm not a good student myself. It's always a lot easier to start looking at these videos than to start studying. This is actualy exactly my subject matter so I guess you guys are helping me out here.
thanks hank and the gang! i have to take my hesi next week and the heart (and the endocrine system) is super complicated to understand from my textbook alone.
HALOUNSC2552 We totally sang it on set shortly before the wrap up. (Unfortunately, not while cameras were rolling, so that one won't make the outtakes. MISSED OPPORTUNITY, I KNOW.) -Nicole
+CrashCourse I highly disagree with you regarding "the heart is just a pump". Science is still not sure if the heart feels or not. But recently many researchers cannot explain why heart receivers feel and change their beliefs just like their heart donors. However, I believe that heart actually controls our brains through neurons connection and I can't wait to prove this via lab experiments.
+Jeseka C Christieson If you is interested in human anatomy the greatest success that I have had was by following the Anatomy Blueprint Pro (just google it) without a doubt the most incredible info i've tried.
Yes, it is possible. And no, they don't live because they're already dead. Heart donors are people who have recently passed away and gave their consent before they died.
My goodness! Where have you been? Thank you so much. I was recently diagnosed with a heart issue and this video helped me understand so much I'm almost crying. Again, thanks!
Love these videos, my A/P professor moves so fast through concepts and these videos break everything down so easy! Thanks for making them for the greater good!
Day 16 of quarantine, it is currently 3 am. I now have to learn off of these videos and I’m half asleep trying to get all my work done and now I actually miss public school.
I've learned more from these videos than I have from my professors and textbooks, for some reason my brain can just never understand the way they explain things but this... THIS and the animations are a godsend!
Okay so I missed a couple of science lessons, mainly where my class learned about all this stuff. And you're telling me that it took them a couple lessons to get through everything. And I learned it all in a 10 minute video.
When exams role around, my classmates desperately scramble to begin their scatterbrained frenzies in an effort to regurgitate facts and figures about the inner workings of the human body. Meanwhile, I say it's time for a Crash Course marathon.
Joe Seph People really need to start to grasp the fact that overpopulation is coming from 3rd world countries. Western countries actually need a higher fertility rate to just continue existing.
If that was the case love would merely be an existing emotion (starting from the early humans) according to Darwin with survival of the fittest. It wouldn't be passed down.. So it would be no love in the first place
Jorge Cisneros crashcourse is a sponsored channel and they have a team of researchers which are medical professionals that contributes to the videos hank hosts.
No joke this has helped me more than actually going to class. I go to my tutorials and the tutors expect us to know everything already AND to make class "interesting" instead of making small relevant jokes, they literally just tell stories. Best part, I can literally just watch this at home and not have to attend since attendance isn't required for the theory classes.
I watched a ton of CrashCourse during a semester when I had a couple psychology courses (I passed both with one B and one A!) So I came back again now that I have A&P. CrashCourse is definitely a lifesaver. It keeps my attention focused, instead of my eyes glazing over and my brain wandering off like it does during alot of other videos with a very monotone, boring narrator. Thank you CrashCourse ❤️
The heart has always fascinated me. It's insane to me that so many grown ups don't understand what the numbers in the pressure stand for. I had, however, forgotten how all the arteries and veins were positioned, so thanks for reminding me :D
Guys remember the acronym LAB RAT

we college students give you our upmost gratitude. Oh Crash Course, thou has saved my grades.
And high schoolers :3
And pre schoolers

How to break a heart (let it go)
The heart on call 24 hours a day.
It is work all throughout the night.
If it sounds like walking on cold snow.
We will rush you to the ER.
It's building pressure up inside.
Gonna let go, through the atrial valve.
Don't eat that cake.
Eat healthy food.
Go to the gym and skip the chips instead produce.
Otherwise you heart is screwd!
Let it be.
It will beat
Even if you don't think of it.
It is your true love.
Whiteout it you would be dead now!
It dosent care about what your crush just said.
Its only job is keeping you alive.

Cool
Am i the only one who was trying to find the heart part 1 by Kendrick Lamar.
I'm a medical student and have a pretty strong stomach for most things but for some reason I just hate hearts - to the point where I've passed out dissecting one. It seems so irrational considering the importance of our and the fact that other organs are absolutely fine for me, but the thought of hearts or the just hearing the sound they make makes me freak out. Great since I'm going to be a doctor, amirite? Loving the anatomy series, helps me recap things I've learned and is funny and interesting.

Good luck with being a doctor!! I am starting my A levels next year 😅
Did you graduate? If so Congratulations! And Cardiology or Cardiovascular wouldn’t be for me
I want to be a doctor but first I have to do ma A-levels
bwahahah! I am trying to get into nursing school and I feel the same way. Im so glad I am not alone!

Had a heart
My tutor taught me this
He didn’t say anything about Biscupid though
Courtesy of ChatGPT:
(Verse 1)
I had a broken heart, I thought it was love
But it was just my blood pressure rising up above
I thought I'd never mend, I thought I'd never thrive
But then I learned to manage, and now I'm feeling alive
(Chorus)
I've got a broken heart, but it's not from love
It's from high blood pressure, from stress and stuff
I take my meds and I watch what I eat
Now my heart is mended, and I'm feeling fleet
(Verse 2)
I used to worry all the time, my stress was through the roof
But now I take it easy, I've learned to be aloof
I exercise and I eat my greens
And now my heart is healthy, and my blood pressure clean
(Chorus)
I've got a broken heart, but it's not from love
It's from high blood pressure, from stress and stuff
I take my meds and I watch what I eat
Now my heart is mended, and I'm feeling fleet
(Bridge)
Don't let high blood pressure bring you down
There are ways to manage it, don't let it get you down
Take care of your heart, and it will take care of you
You'll be feeling healthy, and your heart will be brand new
(Chorus)
I've got a broken heart, but it's not from love
It's from high blood pressure, from stress and stuff
I take my meds and I watch what I eat
Now my heart is mended, and I'm feeling fleet
I hope Hank sees this!
What's the Point?
My heart, your heart...
they all look alike,
two puffy mounds at the top,
tapering down into a spike.
But just why is it
that they all look the same?
Shouldn't a person's heart be
as individual as his name?
Well, if you look a bit closer
you will readily see
that everyone's heart is
just as different as he (or she!).
For it's not the shape,
nor even the size,
But what's inside
that is truly the prize.
The mound on the right...
holds memories so dear
only the good ones
from year after year.
And the mound on the left,
is filled to the brim
with the light of sweet passion,
that never grows dim.
Now the part in the middle,
is where deep love resides.
Its strength can be fierce,
Yet here, too, fragility hides.
Then finally, slowly,
the heart slopes to a fine edge..
coming to a sharp point
in the shape of a wedge.
This point is for balance
between all the parts
which is very important
for those with full hearts!
And if you look more closely
you will see right at the tip
a tiny little hole
no bigger than a pin.
This is the place
where all our sorrows go
They stay with us a short while,
then seep out with the flow.
Hearts can be lonely,
Hearts can be sad...
Hearts can be faithful,
In good times and bad
But no matter the shape,
Nor how big or how small,
Your heart is a gift,
To be shared with all.
this is golden
meh
nice

nice poem
A good way to hear a heart beat without being creepy is to listen to your dog's heart beat
quick tip for ya'll who have a hard time watching it cuz he's going to fast: change the speed in the video to 0.75 and he's actually talking at the speed of a normal human. Really helped me out
4:08 With the valves opening and closing...The heart looks like it's having a party. XD
Sierra Lobo I thought that too; it's like like hand-clapping valves :)
THANK YOU! I’m a visual learner and you helped me see what I was trying to learn, but unsuccessful, through my medical books. 🙏🏽🙏🏽🙏🏽
I know this is not happening but if you could just slow down a bit I could probably understand what you are saying much better
Mr.hank ,I'm a student of class 1 and thank you.For crash course first time I pass in Biology and become the first in class.I'm Anestina,from India.

Get this guy back; do whatever it takes he was the best
I learn so much from these crash courses. Lectures at my school are too short and boring. This crash course I watch with such enthusiasm. Just love it. Thank you for making A&P easy to learn
This is such a great explanation! I had to watch it on .75x speed to catch it all. Thanks!

I'm hoping from the title of the next video that it might talk more about the beating of the heart. I'm interested in the way that the heart's natural pacemaker works, and the way that my pacemaker replaces that function when it goes awry.
KindessisEternal Be careful to take care of your heart. My uncle died to having an abnormal heart recentley. Made worse by paramedics
Sterling Archer explain
take care
Which ones, if you don’t mind my asking
Thank you! This will help on my quiz tomorrow! I was studying all the words but didn’t really understand them.
only 40 seconds in and Hank has already crushed my soul that the heart does not care
Our blood is never blue? My world is shattered.
TheFireflyGrave The diagram in my science textbook in primary school had the veins in blue and the arteries in red to make is clear enough to see the difference,
TheFireflyGrave I heard that it’s possible to have blue blood if you have too much copper in your blood
I'm studying to become a teacher (biology and English)... but I'm not a good student myself. It's always a lot easier to start looking at these videos than to start studying. This is actualy exactly my subject matter so I guess you guys are helping me out here.
You're saving my life this year, I honestly can't thank you enough for this series!
8:59 You could write a song about a heart back in high school trying to write its chemistry final! :)
That could work! :)
thanks hank and the gang!
i have to take my hesi next week and the heart (and the endocrine system) is super complicated to understand from my textbook alone.
Anybody else started to sing "Under Pressure" when they saw this video uploaded?
I DID
HALOUNSC2552 This is the natural thing to do.
HALOUNSC2552 No, but now I am! XD
HALOUNSC2552 We totally sang it on set shortly before the wrap up. (Unfortunately, not while cameras were rolling, so that one won't make the outtakes. MISSED OPPORTUNITY, I KNOW.)
-Nicole
HALOUNSC2552 YES
You helped me get an A in A&P in nursing school last year thank you !!,
I'm pretty sure Hank could write a song on that! xD
Jeseka C Christieson Probably true.

+CrashCourse I highly disagree with you regarding "the heart is just a pump". Science is still not sure if the heart feels or not. But recently many researchers cannot explain why heart receivers feel and change their beliefs just like their heart donors.
However, I believe that heart actually controls our brains through neurons connection and I can't wait to prove this via lab experiments.
+Jeseka C Christieson If you is interested in human anatomy the greatest success that I have had was by following the Anatomy Blueprint Pro (just google it) without a doubt the most incredible info i've tried.
+Nada Alsuhebany heart donors? Then how do the donors live? Is it even possible hahah
Yes, it is possible. And no, they don't live because they're already dead. Heart donors are people who have recently passed away and gave their consent before they died.
Thank you, thank you, thank you. Crash course is the best. I've learnt so much from these lessons.
You saved my ass big time
+Bjørn Gryttingsodegaard or Blood Pressure
+Bjørn Gryttingsodegaard saved me on my last A&p 2 exam lol
+Alix Graham Same here!
same
Bjørn Gryttingsodegaard saaaaame!
My goodness! Where have you been? Thank you so much. I was recently diagnosed with a heart issue and this video helped me understand so much I'm almost crying. Again, thanks!
Love these videos, my A/P professor moves so fast through concepts and these videos break everything down so easy! Thanks for making them for the greater good!
You are the reason why I pass A&P, thank you!
Who's also last minute studying before an exam?
HANK YOU ARE THE MAN!!! Thank You from the base of my heart!!!!!
kendrick lamar reference
the heart is pumping the blood in our body
Cash Course is a good understanding of the information and explains the heart.
heart works about 80 years ( if youre lucky 100 years ) aaaaaaaaaaaaaaaand then it says " fu*k this im too old for this sh*t "
yeyyyyy very funnnnyyyy
Day 16 of quarantine, it is currently 3 am. I now have to learn off of these videos and I’m half asleep trying to get all my work done and now I actually miss public school.
Tunnel Vision here from my teacher Mrs.Brown
My favorite crash course video hands down.
whew this guy makes me nervous, but the info is spot on!
Just had my Aorta repaired in April, take care of your hearts guys, it's not fun to get cut opened
John Hassel thanks man! I was out of the game for a month
Kevin...could you send me an invoice again?
I've learned more from these videos than I have from my professors and textbooks, for some reason my brain can just never understand the way they explain things but this... THIS and the animations are a godsend!
Okay so I missed a couple of science lessons, mainly where my class learned about all this stuff. And you're telling me that it took them a couple lessons to get through everything. And I learned it all in a 10 minute video.
Katrina Wall FORREAL!!

I know how you feel.
When exams role around, my classmates desperately scramble to begin their scatterbrained frenzies in an effort to regurgitate facts and figures about the inner workings of the human body.
Meanwhile, I say it's time for a Crash Course marathon.
If people's hearts actually broke when their date dumped them, we wouldn't have to deal with an overpopulation problem.
Joe Seph People really need to start to grasp the fact that overpopulation is coming from 3rd world countries. Western countries actually need a higher fertility rate to just continue existing.

agentrikamcgee It's not growing. If anything, it's aging.
agentrikamcgee it does have one of the largest populations, but the population growth rate has been steadily declining for decades.
If that was the case love would merely be an existing emotion (starting from the early humans) according to Darwin with survival of the fittest. It wouldn't be passed down.. So it would be no love in the first place
thank you so much crash course team !! ❤❤❤
I LOVE this channel! I’m so glad I came across this. So knowledgeable and easy to absorb. THANK YOU!
Currently studying for the MCAT that I take this Friday. Very helpful video!
7:43 skrillex! you guys are at a whole new level of awesome :)
Saved my life once again !!!! THANK YOU! You explain 1 hour lectures in like 10-15 mins!
How does he know everything about everything?
Jorge Cisneros crashcourse is a sponsored channel and they have a team of researchers which are medical professionals that contributes to the videos hank hosts.
Haha yeah Hank is a smart guy, but he doesn't just come up with this stuff off the top of his head.
wishsnfishs however it looks a lot like that...
He's a wizard.
It's this new and exciting thing scientists have recently discovered: *RESEARCH*
No joke this has helped me more than actually going to class. I go to my tutorials and the tutors expect us to know everything already AND to make class "interesting" instead of making small relevant jokes, they literally just tell stories. Best part, I can literally just watch this at home and not have to attend since attendance isn't required for the theory classes.
I'm not religious but. You guys do the lords work! I learn more from you than half of my professors
I watched a ton of CrashCourse during a semester when I had a couple psychology courses (I passed both with one B and one A!) So I came back again now that I have A&P. CrashCourse is definitely a lifesaver. It keeps my attention focused, instead of my eyes glazing over and my brain wandering off like it does during alot of other videos with a very monotone, boring narrator. Thank you CrashCourse ❤️
all about the LAB RAT, Left Atrium bicuspid, Right Atrium tricuspid
this guy deserves more than half of my degree when i graduate... ALWAYS digging me out of a hole!!!! THANK YOU!!!!
i love his accent, it makes it easier and nicer to listen to biology facts 😂😂😂
This channel is my last chance to pass my test tomorrow. pls pray for me
Anatomy test in 30 mins, having this play as i get ready to leave
The heart has always fascinated me. It's insane to me that so many grown ups don't understand what the numbers in the pressure stand for. I had, however, forgotten how all the arteries and veins were positioned, so thanks for reminding me :D
Who else spent countless amounts of money on tuition and text books just to learn the most from a free youtube video ?
This year I've seen Hank and fellow crew from Crash Course more than I've seen my own family.
Good luck for those who will have their A-level exams
(including me)
