Don't talk to me while I'm eating. I have decided I will no longer answer. And if you tell jokes while I'm eating, I'll swiftly slap you back into silence.
One time I swallowed a pill and it got stuck blocking my airway completely. I couldn’t drink anything to wash it down and my husband tried the Heimlich multiple times and even shoved his finger down my throat. Nothing worked. I fr almost died. After what was probably a min and a half, I accepted that I’m probably going to die. I stayed calm prayed in my head and sure enough a teeny tiny way for me to get some air happened. I just focused on slowly breathing through that until I was able to get enough oxygen to try the Heimlich again. I have extreme ptsd now because of this and can no longer swallow pills. Has to be crushed up from now on. I’ve never been scared to die but now I’m scared of how I’ll die and suffocating is not the way I want to go. That was absolutely horrific and traumatizing
I both have and have not experienced something like that and also have a fear of dying that way. Dear God. I didn't eat or swallow anything that got stuck, but I was like four or five at the doctor's office and the nurse had one of those sticks they put on your tongue to hold it down to look down your throat. Literally the only thing that stopped it from going down my throat WHEN SHE DROPPED IT was me feeling like something bad was going to happen and reaching up to grab it right as her hand pulled away from it. And in that brief second I forgot how to breathe because it was such a horrifying shock. And absolutely no one treated it like a big deal. Which was upsetting and still is. Like, mom and nurse, this almost got DROPPED DOWN MY THROAT. Needless to say I have a fear of getting choked and suffocating, and also of nurses. Amusingly, not doctors. SPECIFICALLY nurses.
Hugs to you! My dad saved my grandmother twice with the Heimlich maneuver(at the dinner table, we children witnessed it). She always cut her food into teeny tiny pieces( i think because of fear of choking) ever afterwards.
I started choking a few years ago when I was home alone. Idk how the food went down wrong but it did. I could not get any air in at all. I realized I might die like this and could only imagine my husband finding me dead on the floor when he got home. I somehow managed to cough with whatever air I had left in my lungs and it actually pushed the food out. To this day I am phobic of eating alone. I agree, suffocating is really a horrible way to go. Glad we're all still alive!!
For anyone wondering, this head belonged to an elderly man. You can tell by the worn skin, nose shape and thin hair on the back of the head. I’m sure he has a fulfilling life and I thank him for donating his head for us to learn :)
5:55 Most mammals are equipped with anatomy that lets you breathe *and* drink at the same time, but the human body was optimized for speech, so yeah...
Hmmm... Could you give some source that I could read about mammals being able to breathe and drink at the same time? I have hard time imagining that and the first thing that came up in a search actually states otherwise (as one might expect) I guess I should clarify what you mean by "at the same time", because I assumed you meant a continuous stream of liquid instead of swallowing and then breathing in, which... Isn't really simultaneous and is quite trivial for humans too
His enthusiasm is infectious and makes it even more fun to learn about this stuff that might otherwise make one squeamish. Love this! Makes you realize just how amazing our bodies are.
agree, but without forcing the learning how would you even get basic understanding of most topics, placing you education into the hands of the youtube recommendation algorithm?
@@tuyiren781 thats fine, but sometimes we get to learn about stuffs like "that guy's name in year 1500 invented this and that" its cool info but it won't really change our lives drastically, not 100% necessary.
@@tuyiren781 Good teachers who love the topic and teaching That's why I love and am proficient at English, physics and chemistry. The teachers I had as a kid were awesome and always made us laugh
This is an evolutionary trade-off which allows us to speak. If I recall correctly, we're the only species that can choke on food... Other great apes cannot because the "tubes" come together much higher in chimps and others. They literally can't get food into the throat unless their trachea is fully closed by the epiglotis. (Other primates can make noise and communicate, but the range of sounds isn't as broad.)
I heard that this is the reason why a lot of dementia patients finally die of pneumonia - as they lose the brain's ability to coordinate the muscles involved in chewing and swallowing, there is a higher risk of food entering the lungs. My father was a case in point, when he passed away in 2018.
I am recovering from laryngeal cancer and the treatments it took to get rid of it. My epiglottis doesn't close totally so I do a whole lot of choking. g. This is the most information I've gotten on what's going on down there from anyone in the 2 years that I've been dealing with this stuff. Thank you!
I am not a med student, but an engineer. But I immensely love your videos. Jonathan and Justin are just so amazing and make learning about anatomy so fun and interesting. even with the occasional jokes and funny moments, which i love. waiting eagerly for more videos in the future.
same. i went for Engineering bcs it was more affordable (and i did had fun, i love math and physics it's like solving games) but i would have loooove to go into meds (if i could afford to) just for the sake of studying endless things
Being an Adult now, I literally think everything I learned in School was a waste of time. The only Thing in this World that matters was never Taught to me, Money.
As someone who's deathly afraid of choking/getting food or water down the "wrong tube" (keep in mind, theres usually a lot of saliva in my mouth so I need to swallow every five seconds or so) this video helped me understand what's going on in my body more. Thanks man, I appreciate it :)

This is so interesting, this is why I am on a feeding tube. It goes down the wrong pipe! I have a brain lesion in the base of my brain and it affects all of my functions like walking, talking, swallowing properly etc . Thank you for lesson!
I'm glad you're on a feeding tube, so you don't have to worry about asperating! Are you able to walk and talk, or is it just harder for you? I hope you don't mind the questions. Take care.
Sometimes it helps to know what the mechanics are to your issue, God bless and I hope all goes well for you. My daughter has a feeding tube, born premature to a drug mother (not me we adopted her) at 23 weeks she kept aspirating and had to have the tube, she had 8 operations in total. So I know what a blessing they can be. I had the only baby on the block that you could feed while she was asleep.
@@brenda324 Prayers for your daughter. That's a lot of surgery for such a young baby--if it all happened early on. It's a lot regardless. I'm so glad you adopted her. I hope she's doing well. I have a friend on a feeding tube. She has a genetic condition that caused her stomach to not work properly. It's awful what can happen when things go wrong in our bodies. It does hehlp to understand the medical details behind it all. Helps make it not so scary, I'd think.
Wow! That was fascinating, and so well explained. Thank you for an excellent, informative presentation! I'm 73 and when I was 13 or 14, my mom had a series of serious operations where her esophagus was removed and her colon was pulled up and made into one, and her stomach was moved over and up. Amazing - especially for the times. Part of the original problem was that food kept going down the wrong pipe and she had bouts of strangling, nearly asphyxiating, etc. In the invoice details, the doctor said that, apart from the major work, a flap was also inserted to prevent regurgitation. We always wondered about that and where, exactly, it might have been placed. I guess it was similar to the epiglottis but I wonder how they made it allow food to pass down but not come back up. She lived another 45 or more years and never did regurgitate again but also didn't have any problems eating and/or breathing!
They making money off your organs instead of donating them for people in need they reserve them if you got funds unless you pick someone in specific to donate shit fucked up
I suffer from pretty extreme anxiety. So every time I eat I have to be totally concious when I swallow as I choke through most of my meals. It is extremely exhausting and needless to say eating is not enjoyable in any way. When I am not as anxious I am good to go. Thanks for this very interesting video and perhaps it will help me in the future to understand and relax.
@@SPONTANE66 as far as I know mine is from anxiety. There is throat issues that could rarely come up to cause trouble swallowing . See your doctor to,rule out the objective alternatives first.
I was eating as he was explaining that "if you breath in or laugh or hiccup as you swallow that's how it goes down the wrong tube" and I suddenly had an overwhelming urge to try and breath as I swallowed my bagel. Anyway, don't try it, it's not worth a trip to the emergency room over.
if you’re alone, I’m pretty sure you’re supposed to call 911 and leave them on the line while you do whatever you can to dislodge the food. if you were with someone that just couldn’t help you, I guess it makes a little sense to go to the ER. still sus tho
You can tell this is being presented by someone who cares a lot about the content. That comes across in body language and inflection, and it adds a LOT to the quality of this video and the ability to keep attention. This video is very well-done for the most part, and I really enjoyed it!
My thoughts exactly -- I occasionally experience random bursts of anxiety that makes it progressively more difficult, until literally impossible (temporarily), to swallow while eating a meal.
This has been happening several times a day now. I'm not sure why but it's been going on now for like three months. Two to four times a day this has been happening.
It’s possible you are eating too fast, It happens to me many times a day too. I’m almost certain it’s because I vacuum my food and drinks down my throat😂
I'd speak to your doctor about it as there are things can can make this more likely to happen. My Dad's Parkinson's causes him to do that. It's a big worry as this is what causes 80% of deaths in Parkinson's patients.
I always regret watching videos about how my body works, it makes me feel a lot more vulnerable knowing how complex we actually are. Now I'm never going to eat, drink or breath again without thinking about what this weird little flap on my neck is up to.
Or just hold your breath while eating. I always wonder why my mom always said don't talk while eating or chew your food properly, I guess this is why. Turns out old sayings sometimes have a logical explanation behind it.
same the feeling that everytime you swallow you have a chance to just die because that shitty ass epiglottis will just refuse to work if you breathe/laugh while eating and there is nothing else that can help you besides chocking is making me so scared that im never eating and drinking again fvck anatomy human body sucks
As a Speech-Language Pathologist who both diagnoses and treats dysphasia or difficulty swallowing, I greatly enjoyed the description of how respiration and swallowing are delicately coordinated with ensuring foods and liquids enter the esophagus rather than into the trachea. Please make note that while the epiglottis can play a large function in the mechanics of protecting the airway during swallowing, it is usually NOT the primary means! In fact, the vocal folds (I.e. the muscles that create sound for speech) lying just under the epiglottis are our main source of protection from food and liquid entering the airway. Typically as we swallow, the epiglottis folds down while the vocal folds shut tightly. You can view the vocal folds as the primary barrier to prevent food and liquid from entering the airway and the epiglottis as a secondary precautionary means to further assist with safety. As a take away, many can still swallow safely without the epiglottis protecting the airway but without the vocal folds we are at a much higher risk for aspiration!
@@amelieleclerc-poudrier7003 Interesting! Seems kind of strange they don't mention this. Is this very new information, or? I've had a rip in my vocal chords when I had whooping cough (?google translate much). Lost my voice for weeks. Actually saw them through a camera, was very interesting. Would this affect my protection? Cause I'm always a little scared about that area. Together with my chronic bronchites, making me cough a lot and this scar tissue on the vocal chords.. Doctor shrugged it off and just said I couldn't be a singer anymore. But IDK..
Years ago a speech pathologist mentioned that I should turn my head to the left or right, when I have trouble swallowing food. But I can't remember which way she said to turn and I've always wondered about the mechanics of turning and how that helped. Any thoughts on that?
Sometimes that little flap won’t work as well as it should but that’s okay. I’m a speech pathologist and I help a lot of patients with swallowing problems. In addition to the epiglottis, the closure of the false vocal folds and the true vocal folds create additional set of valves that close off the airway. So if the epiglottis doesn’t completely close off the airway, there are other mechanisms in place. I’ve worked with patients who still are able to swallow even without that epiglottis fully inverting.
Is the flap to blame if you get food up toward your nasal passages instead? I don’t know what I do wrong, but I struggle with swallowing small and somewhat sticky food like rice. I’d say it’s as often as every other meal I get rice up there, and it’s not stuck high enough to be blown out through my nose, neither low enough for my throat muscles to be able to push it in the same direction. On top of that, if I lay down and wait for it to slide down, it triggers my swallowing reflex before it has slid far enough, pushing it back up again….
@@CROWFACEDHey! Normally when we swallow the passageway to the nose is closed off completely by the soft palate to prevent food or liquid from going up the nasal cavity. Swallowing is a pretty complex movement pattern so I’d recommend you communicate your symptoms with your physician and maybe get a referral for an ENT physician or speech pathologist to further look into your swallowing issue.
@@rjkun16 Thank you for your reply, it's very appreciated! I have a genetic condition that have a tendency to lead to (usually) minor deformities along the axis of our bodies that is mirrored. I have a gap between my front teeth, I used to have a tied tongue, and I have a minor scoliosis. Since the soft palate is centered, it wouldn't surprise me if it has been affected by this gene too, even if just to a small degree. Would be interesting to check out!
That was very interesting to watch. I just had a friend of my moms just diagnosed with Lou Gehrig’s disease and she’s at later stages where she can’t talk and can’t swallow ,now I can see kind of what things are being affected in that part of the throat. So sad.
@@cool_bug_facts my guess is that you’ve probably got to be checked quite a bit beforehand, and maybe even given a licence to carry, for an event such as getting pulled over, like you mentioned.
Thank you for explaining this! My grandpa died two weeks ago from aspiration pneumonia, which resulted in an empyema and sepsis that eventually killed him. He had a disease that weakened the muscles that make the epiglottis contract, so eventually, everything he would eat or drink, even saliva started to be inhaled. Seeing and understanding this process anatomically really helped me to process his death, because it all happened so quickly. Thank you so much for educating us!
I threw up while under anesthesia , and had respiration pneumonia , your comment helps me understand why they didn’t think i would survive . Was in the icu for almost two weeks
From an engineer's perspective, how an elegant piece of machine our human body is. Every little thing serves its purpose in keeping this machine working 24X7.
That's the reason why speech-language pathologists always call it "the swallow mechanism." You are absolutely right, it is such a machine that requires specific timing, pressures, contractions, and precision!
The next version could definitely use some better machining. Dunno why the engineers thought a tail bone was necessary. Having the nasal and oral cavity connected is also a serious flaw. Designers also for some reason based the spine on quadrapeds? The software also has some serious problems, been some recent viruses I think, depression, anxiety, and others I can't name rn.
This has got to be the best channels everrrrrrrr..... Highly recommended for high school students or even middle school students passionate about medical science.

Probably the worst "wrong tube" moment I've had was with habanero hot sauce. Probably the second most painful thing I've had happen besides catching a brutal shot to the nuts.
When I was a kid, I'd try to see how far I could get tiny drops of soda down the back of my mouth before my body would be forced to gulp; trying to basically breath and drink soda at the same time... *I was a dumb kid.*
When I have a sore throat, I try to get the saltwater as far back as I can without swallowing it. It is a strange feeling for sure, but sometimes a little goes down the very beginning of the trachea but I can feel that it doesn't go all the way down. Also I don't think it would be as much of an issue because the water would evaporate and the salt would(I think) just absorb.
@@N20Joe It would, but that's still very dangerous. We don't know what happens if too much salt builds up in our lungs, but I wouldn't want to find out. You're better off buying coughing syrup.
Very informative video, I especially liked seeing the dissection, though it was not like when they show them in a movie, the tissue color made it hard to tell where the tongue was. I liked the explanation of the types of cartilage in nose and ear and the cartilage rings in the throat. Nifty stuff. Its amazing how complicated our bodily functions are and how much of our body works "automatically", like the coughing reflex.
How many people come in the freaking realize that’s actually someone’s head that used to be alive you’re literally holding a dead head they used to breathe and talk……..it’s an feeling you can’t describe honestly
My sons grandfather has a condition where that flap spasms, or doesn’t close all the way from being intubated. Any time he eats it’s always an issue and it has caused him to choke a few times because of it.
I think that’s a fairly common problem in older people. My grandmother had the same issue. She also had to have her esophagus stretched because she’d often get choked on the food she was eating because it wouldn’t go all the way down.
@@soyburglar77 I am 59 and for quite a few years I've been choking quite regularly especially on bitty foods like nuts, biscuits, coconut etc. It horrible and frightening.
@chloe Jones I totally understand. I’m 44 and for quite a few years I’ve been having the issue of food getting stuck in my esophagus. I have to be really careful when eating things like chicken and rice, which always seems to give me issues. I say we’re just poorly designed, lol. Why would you put the food tube right next door to the breathing tube?! Something is bound to go wrong!
Sometimes all it needs is a drop of water to hit the wrong the wrong tube/area and, I think it’s that little flap that closes and you cannot breathe in. It’s really really scary but it passes within a minute or two.
Experienced that One time when i used a tonguescrape while taking a shower. Suddenly from No where i couldnt breath at all for almost 15 seconds and i totally paniced wich only made the situation worse. Never used a tonguescrape or a toothbrush in shower since then.
When you are about to cough , but you can't because there is not air in your lungs , so you try to inhale , but you can't because that flap is closed because of the cough reflex , so your diaphragm spasms and you are just left there trying to inhale and exhale at the same time
@@Fastwalker27 Reading this comment triggered my anxiety for some reason even though it's never happened to me and I suddenly felt like it was difficult to breathe.
Thank you Justin. Your presentation is most informative and although I was not completely ignorant of the processes you describe, you make it very interesting to "refresh" our knowledge.
@@RonJohn63 i don't know about your elders .....but my grandparents often insist not to speak while eating or else we would choke..know i found the reason .. that's it. More over they won't be disgusted to see my mouth full of food and mangled words...everyone are not same ..right???
If there are chances that I have to speak but got a food on my mouth. I will cover my mouth with my hand so they will not see the inside of my mouth as I speak.
This is insane to hear. It gives me so much insight on what happened to me as a kid! When I was 4 years old, I aspirated a piece of steak fat into my lung and developed a serious infection. 104 degree fevers and all of that fun stuff. I wound up in a Childrens hospital for a month. I was born with a deformed lung and it happened to lodge itself right in that spot in my lung and made it look normal, so it took quite a while for them to find it in any scans. I saw 14 specialists a day and once it was found, they had to regrow it in their lab and develop their own medicine for me to fight off that infection 🥴 TLDR: I wound up in the hospital for a month at the age of 4 due to aspiration.
this is why accidentally inhaling food into my lungs is one of my persistent phobias. i still remember how messed up my nephew was when he inhaled a piece of banana. oof.
I just discovered your channel and it must be one of the best ones I found. I am a nurse assistant so I used to take care of elderly and I remember how badly we were taught to be careful of patients position when feeding to avoid aspiration. When I asked what it was the nurses just told me "the wrong tube" so even if Im not new to this concept I have never seen it so clearly. Thank you for your videos and to take the time to teach
To add: Not just while you’re feeding them, but 30 mins after the last bite of food or swallow of drink, they need to remain upright. That is, if they have Dysphagia like my dad did. I found some CNAs were laying him down after feeding and he was then vomiting. He had Dementia with the Dysphagia, so could never advocate for himself. 😔 I miss him so much.
I have been told that subvocalization can also cause one to aspirate material. Subvocalization occurs when one is listening to a conversation and although you may have no intention of personally speaking, if you think of something to say, all of the muscles involved in speaking can move, as if you are actually speaking, and cause the epiglottis to open.

As a survivor of radiation treatment to this area for throat cancer this presentation is especially interesting. The radiation damages and changes the elasticity and function of some of these tissues, making me VERY aware of this process that occurs without thought for most people. One positive side benefit (other than being alive) is that due to the tightening of these tissues, I no longer have any trace of sleep apnea... 👍 Thanks for this presentation!

Watching a video like this just makes me realize the importance of having cadavers available to teachers/students; all in an effort to improve the lives of future generations. Yes, everything in the video can be taught with animation, but doctors need cadavers to develop the needed skills.

This is very interesting I’ve just had really bad pneumonia while I was recovering from a operation, it’s fascinating to se exactly how it happened. Thanks for making these videos.
Aspiration pneumonia is not solely from aspiration of food and liquid. In actuality, the term is a blanket term to cover types of pneumonia that are not from a viral source. Think of the aspiration of food and liquid as the powder keg (consumable proteins and sugars) and aspiration of bacteria from the environment as the match. The bacteria thrive with the fertilizer in the warm, moist environment of the lungs. But, this is only component of pneumonia. Not all people who have pneumonia aspirate, and not all people who aspirate get pneumonia. I've done countless of swallow x-rays on people with clear lungs. Your cardiopulmonary status, level of mobility, comorbidities, and overall physical health also play just as large of factors when it comes to getting pneumonia. I've had lots of patients with normal swallows who develop pneumonia after falling at home or after a major operation because they're not up and physically mobile like usual.
My 58 year old brother swallowed a bit of ice cold water that went straight to the lungs and he went into cardiac arrest and 25 minutes of cpr could not bring him back. Last October. Rip Bro

Then you better make plans now to do so because after you’re dead, it’s not up to you anymore, unless you have specific plans that you paid for and had filed with authorities.
Considering my father died because of something going down the "wrong tube" I'd say that yes, it is pretty darn bad.... Three hospitals refused to even let us in because they thought he drank poison. And the doctors of the fourth one tried to do CPR(if you can call punching his chest repeatedly, no mouth to mouth CPR) but by then it was already to late.
I am sorry for your loss. That is a horrible way to go. Also, chest punching was a cpr technique used in old wartime, we don't do it now because, we don't need to.
@@jaztin7197 Unfortunately they aren't. Hospitals have the right to refuse patients for any reason. Most of the time it's one of two reasons - they're full and your condition is either not as serious as other patients or your condition is so serious that you are less likely to live than other patients, so they take them instead. And the other reason they refuse you is if ou require a risky surgery and the hospital doesn't want to be liable if a nurse screws up or you die anyway. This is the example where greed kills.

I would do the same, once in school I laughed at a joke while drinking oj, started choking and I couldn’t breathe for a long time
oh,I would kill anyone who tells me a joke while I'm eating
good. its impolite anyway
One time I swallowed a pill and it got stuck blocking my airway completely. I couldn’t drink anything to wash it down and my husband tried the Heimlich multiple times and even shoved his finger down my throat. Nothing worked. I fr almost died. After what was probably a min and a half, I accepted that I’m probably going to die. I stayed calm prayed in my head and sure enough a teeny tiny way for me to get some air happened. I just focused on slowly breathing through that until I was able to get enough oxygen to try the Heimlich again. I have extreme ptsd now because of this and can no longer swallow pills. Has to be crushed up from now on. I’ve never been scared to die but now I’m scared of how I’ll die and suffocating is not the way I want to go. That was absolutely horrific and traumatizing
I both have and have not experienced something like that and also have a fear of dying that way. Dear God. I didn't eat or swallow anything that got stuck, but I was like four or five at the doctor's office and the nurse had one of those sticks they put on your tongue to hold it down to look down your throat. Literally the only thing that stopped it from going down my throat WHEN SHE DROPPED IT was me feeling like something bad was going to happen and reaching up to grab it right as her hand pulled away from it. And in that brief second I forgot how to breathe because it was such a horrifying shock.
And absolutely no one treated it like a big deal. Which was upsetting and still is. Like, mom and nurse, this almost got DROPPED DOWN MY THROAT. Needless to say I have a fear of getting choked and suffocating, and also of nurses. Amusingly, not doctors. SPECIFICALLY nurses.
I laughed one time and milk came out of my nose. Worst thing I’ve ever experienced.
Hugs to you! My dad saved my grandmother twice with the Heimlich maneuver(at the dinner table, we children witnessed it). She always cut her food into teeny tiny pieces( i think because of fear of choking) ever afterwards.
I started choking a few years ago when I was home alone. Idk how the food went down wrong but it did. I could not get any air in at all. I realized I might die like this and could only imagine my husband finding me dead on the floor when he got home. I somehow managed to cough with whatever air I had left in my lungs and it actually pushed the food out. To this day I am phobic of eating alone. I agree, suffocating is really a horrible way to go. Glad we're all still alive!!
Omg I just put like 15 pills I talked every morning all at once . You have unlocked another fear in me 😢😢ty❤

This is an evolutionary trade-off which allows us to speak. If I recall correctly, we're the only species that can choke on food... Other great apes cannot because the "tubes" come together much higher in chimps and others. They literally can't get food into the throat unless their trachea is fully closed by the epiglotis. (Other primates can make noise and communicate, but the range of sounds isn't as broad.)

Sometimes it helps to know what the mechanics are to your issue, God bless and I hope all goes well for you. My daughter has a feeding tube, born premature to a drug mother (not me we adopted her) at 23 weeks she kept aspirating and had to have the tube, she had 8 operations in total. So I know what a blessing they can be. I had the only baby on the block that you could feed while she was asleep.
@@brenda324 Prayers for your daughter. That's a lot of surgery for such a young baby--if it all happened early on. It's a lot regardless.

I have a friend on a feeding tube. She has a genetic condition that caused her stomach to not work properly.
It's awful what can happen when things go wrong in our bodies. It does hehlp to understand the medical details behind it all. Helps make it not so scary, I'd think.
Wow! That was fascinating, and so well explained. Thank you for an excellent, informative presentation! I'm 73 and when I was 13 or 14, my mom had a series of serious operations where her esophagus was removed and her colon was pulled up and made into one, and her stomach was moved over and up. Amazing - especially for the times. Part of the original problem was that food kept going down the wrong pipe and she had bouts of strangling, nearly asphyxiating, etc. In the invoice details, the doctor said that, apart from the major work, a flap was also inserted to prevent regurgitation. We always wondered about that and where, exactly, it might have been placed. I guess it was similar to the epiglottis but I wonder how they made it allow food to pass down but not come back up. She lived another 45 or more years and never did regurgitate again but also didn't have any problems eating and/or breathing!
These guy's are great teachers! Interesting and humorous.

It is extremely exhausting and needless to say eating is not enjoyable in any way. When I am not as anxious I am good to go. Thanks for this very interesting video and perhaps it will help me in the future to understand and relax.
Me too mate. Massive anxiety when it comes to swallowing. Very little anxiety in other areas of life.
I have this too, it's really awful. It feels like such an abnormal and hyper specific problem
I wanted to ask you, is this just cause by anxiety. This to also happens to me.
@@SPONTANE66 as far as I know mine is from anxiety. There is throat issues that could rarely come up to cause trouble swallowing . See your doctor to,rule out the objective alternatives first.
I was eating as he was explaining that "if you breath in or laugh or hiccup as you swallow that's how it goes down the wrong tube" and I suddenly had an overwhelming urge to try and breath as I swallowed my bagel.
Anyway, don't try it, it's not worth a trip to the emergency room over.
ER? If it's stuck inside throat, you can't wait
if you’re alone, I’m pretty sure you’re supposed to call 911 and leave them on the line while you do whatever you can to dislodge the food. if you were with someone that just couldn’t help you, I guess it makes a little sense to go to the ER. still sus tho
im quite sure you will die in like 2 minutes if you get asphyxiated, there wont be any need for ER
you either cough it out or you die on spot
You wont even make it to the emergency room LOOOOL!!!

This has been happening several times a day now. I'm not sure why but it's been going on now for like three months. Two to four times a day this has been happening.
It’s possible you are eating too fast, It happens to me many times a day too. I’m almost certain it’s because I vacuum my food and drinks down my throat😂
I'd speak to your doctor about it as there are things can can make this more likely to happen. My Dad's Parkinson's causes him to do that. It's a big worry as this is what causes 80% of deaths in Parkinson's patients.
Please tell your Doctor.

the feeling that everytime you swallow you have a chance to just die because that shitty ass epiglottis will just refuse to work if you breathe/laugh while eating and there is nothing else that can help you besides chocking is making me so scared that im never eating and drinking again
fvck anatomy human body sucks
Right. My anxiety 😰 I can’t watch
As a Speech-Language Pathologist who both diagnoses and treats dysphasia or difficulty swallowing, I greatly enjoyed the description of how respiration and swallowing are delicately coordinated with ensuring foods and liquids enter the esophagus rather than into the trachea. Please make note that while the epiglottis can play a large function in the mechanics of protecting the airway during swallowing, it is usually NOT the primary means! In fact, the vocal folds (I.e. the muscles that create sound for speech) lying just under the epiglottis are our main source of protection from food and liquid entering the airway. Typically as we swallow, the epiglottis folds down while the vocal folds shut tightly. You can view the vocal folds as the primary barrier to prevent food and liquid from entering the airway and the epiglottis as a secondary precautionary means to further assist with safety. As a take away, many can still swallow safely without the epiglottis protecting the airway but without the vocal folds we are at a much higher risk for aspiration!
As a SLP too, I came here to write the same thing, and was glad someone did it before!
@@amelieleclerc-poudrier7003 Interesting! Seems kind of strange they don't mention this. Is this very new information, or?

Would this affect my protection? Cause I'm always a little scared about that area. Together with my chronic bronchites, making me cough a lot and this scar tissue on the vocal chords..
Doctor shrugged it off and just said I couldn't be a singer anymore. But IDK..
Thanks for that Doc
Thank You! I was about to comment the same.
Years ago a speech pathologist mentioned that I should turn my head to the left or right, when I have trouble swallowing food. But I can't remember which way she said to turn and I've always wondered about the mechanics of turning and how that helped. Any thoughts on that?
Sometimes that little flap won’t work as well as it should but that’s okay.
I’m a speech pathologist and I help a lot of patients with swallowing problems. In addition to the epiglottis, the closure of the false vocal folds and the true vocal folds create additional set of valves that close off the airway. So if the epiglottis doesn’t completely close off the airway, there are other mechanisms in place.
I’ve worked with patients who still are able to swallow even without that epiglottis fully inverting.
Is the flap to blame if you get food up toward your nasal passages instead? I don’t know what I do wrong, but I struggle with swallowing small and somewhat sticky food like rice. I’d say it’s as often as every other meal I get rice up there, and it’s not stuck high enough to be blown out through my nose, neither low enough for my throat muscles to be able to push it in the same direction. On top of that, if I lay down and wait for it to slide down, it triggers my swallowing reflex before it has slid far enough, pushing it back up again….
@@CROWFACEDHey! Normally when we swallow the passageway to the nose is closed off completely by the soft palate to prevent food or liquid from going up the nasal cavity.
Swallowing is a pretty complex movement pattern so I’d recommend you communicate your symptoms with your physician and maybe get a referral for an ENT physician or speech pathologist to further look into your swallowing issue.
@@rjkun16 Thank you for your reply, it's very appreciated! I have a genetic condition that have a tendency to lead to (usually) minor deformities along the axis of our bodies that is mirrored. I have a gap between my front teeth, I used to have a tied tongue, and I have a minor scoliosis.

Thank you for explaining this! My grandpa died two weeks ago from aspiration pneumonia, which resulted in an empyema and sepsis that eventually killed him.

It’s cool when it works but this video was made because it’s so common for it to fail. Not a very well engineered design
The next version could definitely use some better machining. Dunno why the engineers thought a tail bone was necessary. Having the nasal and oral cavity connected is also a serious flaw.

When I was a kid, I'd try to see how far I could get tiny drops of soda down the back of my mouth before my body would be forced to gulp; trying to basically breath and drink soda at the same time...
*I was a dumb kid.*
When I have a sore throat, I try to get the saltwater as far back as I can without swallowing it. It is a strange feeling for sure, but sometimes a little goes down the very beginning of the trachea but I can feel that it doesn't go all the way down. Also I don't think it would be as much of an issue because the water would evaporate and the salt would(I think) just absorb.
@@N20Joe It would, but that's still very dangerous. We don't know what happens if too much salt builds up in our lungs, but I wouldn't want to find out. You're better off buying coughing syrup.
i always do this- 😐
I had a friend who could swallow a noodle and make it come out of his nose, he was dumb kid.
Feels nice knowing I'm not the only person that did that
Very informative video, I especially liked seeing the dissection, though it was not like when they show them in a movie, the tissue color made it hard to tell where the tongue was. I liked the explanation of the types of cartilage in nose and ear and the cartilage rings in the throat.
Nifty stuff.
Its amazing how complicated our bodily functions are and how much of our body works "automatically", like the coughing reflex.
How many people come in the freaking realize that’s actually someone’s head that used to be alive you’re literally holding a dead head they used to breathe and talk……..it’s an feeling you can’t describe honestly
Yeah truly unsettling
Thanks to those who donated their body to science and research
And it's literally cut in half... Actually insane
Think about all the memory's and life experiences, just in that head alone
Yucka! But also very interesting...I may donate my body to science, I won't need it after I konk off.
My sons grandfather has a condition where that flap spasms, or doesn’t close all the way from being intubated. Any time he eats it’s always an issue and it has caused him to choke a few times because of it.
Damn it must suck to eat and drink, basically all day long it sucks i can’t imagine.
I think that’s a fairly common problem in older people. My grandmother had the same issue. She also had to have her esophagus stretched because she’d often get choked on the food she was eating because it wouldn’t go all the way down.
@@soyburglar77 I am 59 and for quite a few years I've been choking quite regularly especially on bitty foods like nuts, biscuits, coconut etc. It horrible and frightening.
@chloe Jones
I totally understand. I’m 44 and for quite a few years I’ve been having the issue of food getting stuck in my esophagus. I have to be really careful when eating things like chicken and rice, which always seems to give me issues. I say we’re just poorly designed, lol. Why would you put the food tube right next door to the breathing tube?! Something is bound to go wrong!
It happens to me quite often, I am 61. Sometimes I even choke of water.
Sometimes all it needs is a drop of water to hit the wrong the wrong tube/area and, I think it’s that little flap that closes and you cannot breathe in. It’s really really scary but it passes within a minute or two.
Experienced that One time when i used a tonguescrape while taking a shower.
Suddenly from No where i couldnt breath at all for almost 15 seconds and i totally paniced wich only made the situation worse.
Never used a tonguescrape or a toothbrush in shower since then.
What I didn't know this was a thing
When you are about to cough , but you can't because there is not air in your lungs , so you try to inhale , but you can't because that flap is closed because of the cough reflex , so your diaphragm spasms and you are just left there trying to inhale and exhale at the same time
Yes! And have you ever inhaled quickly while eating and inhaled a pea or something??? Something that tiny can really wreck your day, lol.
@@Fastwalker27 Reading this comment triggered my anxiety for some reason even though it's never happened to me and I suddenly felt like it was difficult to breathe.
Thank you Justin. Your presentation is most informative and although I was not completely ignorant of the processes you describe, you make it very interesting to "refresh" our knowledge.
Brilliant, now let's do "How BAD Is It When Something Goes In the "Wrong Hole"????
"Let's find out!"
*several men walk in*
**bonk**
down bad
both holes are good
@Kudanira come on
Now i understand why elders advice not to speak while eating 🙁
The real reason is that we don't want to see the food in your mouth, or hear the words mangled.
@@RonJohn63 we know.
@@thefailure7789 apparently OP didn't know.
@@RonJohn63 i don't know about your elders .....but my grandparents often insist not to speak while eating or else we would choke..know i found the reason .. that's it.
More over they won't be disgusted to see my mouth full of food and mangled words...everyone are not same ..right???
If there are chances that I have to speak but got a food on my mouth.
I will cover my mouth with my hand so they will not see the inside of my mouth as I speak.
This proves that the human body is both a blessing and a curse.
you didnt know that already?
Very interesting, great way to teach a complicated subject.

-You wanna see something cool then?"
This is insane to hear. It gives me so much insight on what happened to me as a kid! When I was 4 years old, I aspirated a piece of steak fat into my lung and developed a serious infection. 104 degree fevers and all of that fun stuff. I wound up in a Childrens hospital for a month. I was born with a deformed lung and it happened to lodge itself right in that spot in my lung and made it look normal, so it took quite a while for them to find it in any scans. I saw 14 specialists a day and once it was found, they had to regrow it in their lab and develop their own medicine for me to fight off that infection 🥴
TLDR: I wound up in the hospital for a month at the age of 4 due to aspiration.
Wait, what did they regrow in a lab? Your lung?
@@stephd479 probably the bacteria
@@stephd479 free lungs
i did the same thing with a cashew when i was 5 or 6, my parents quickly noticed i was wheezing and we had it removed
this is why accidentally inhaling food into my lungs is one of my persistent phobias. i still remember how messed up my nephew was when he inhaled a piece of banana. oof.
I just discovered your channel and it must be one of the best ones I found. I am a nurse assistant so I used to take care of elderly and I remember how badly we were taught to be careful of patients position when feeding to avoid aspiration. When I asked what it was the nurses just told me "the wrong tube" so even if Im not new to this concept I have never seen it so clearly. Thank you for your videos and to take the time to teach
To add: Not just while you’re feeding them, but 30 mins after the last bite of food or swallow of drink, they need to remain upright. That is, if they have Dysphagia like my dad did.
I found some CNAs were laying him down after feeding and he was then vomiting. He had Dementia with the Dysphagia, so could never advocate for himself. 😔
I miss him so much.
So amazed. It's easier to learn when you have someone teaching like this .
I love these videos, my memory doesn’t retain much, but every little bit helps..
Your passion for these things is visible and appreciated! Makes for a more engaging learning experience
The fact that I'm staring at a piece of what was once a talking, functioning human being is kinda surreal.
Takes the "Hay Kids, wanna see a dead body?" to a whole new level
You get used to it eventually
Well every human dies soo......
The fact that someone that knows human body says something like "flappy thing" made my day 😂
I have been told that subvocalization can also cause one to aspirate material. Subvocalization occurs when one is listening to a conversation and although you may have no intention of personally speaking, if you think of something to say, all of the muscles involved in speaking can move, as if you are actually speaking, and cause the epiglottis to open.
This is one of the shittiest and flimsiest mechanisms that literally keeps us alive.
So it's basically a GM Transmission?
@@robl884 hahaha
@@picax8398 swear I've replaced more 4L60E transmissions in GM trucks over the years than I care to admit lmao. They're great transmissions...until about 120,000-145,000 miles and they start to literally fall apart

I'm a registered donor, I can only hope that my meat bag will be this useful to humanity.
@@operator8014 that's awesome of you! I'm a med student and I'll admit, after cutting these bodies up myself I'm hesitant to donate... Obviously I wouldn't feel it because I'd be dead... But I think it's just the surrealism inherent in putting myself in the cadaver's position as I cut him/her up.
And yes, I am eating dinner while you explain using a cadaver, after working 13 hrs. My problem has always if been I have to smell it…
As a survivor of radiation treatment to this area for throat cancer this presentation is especially interesting. The radiation damages and changes the elasticity and function of some of these tissues, making me VERY aware of this process that occurs without thought for most people. One positive side benefit (other than being alive) is that due to the tightening of these tissues, I no longer have any trace of sleep apnea... 👍 Thanks for this presentation!
I didnt know how badass the
epiglottis was until today, i will tattoo "EPICglottis" on my arm in show of respect and praise towards the best tissue of my body.
Don't. That sounds stupid
please do this, it sounds amazing
👏👏👏👏
Thank you! As someone dealing w swallowing/breathing problems due to after effects of radiation for throat cancer, this visualization was extremely helpful!
This is really ‘cool’ and done very well. Thanks for the presentation with actual human body rather than pictures and diagrams.
Watching a video like this just makes me realize the importance of having cadavers available to teachers/students; all in an effort to improve the lives of future generations. Yes, everything in the video can be taught with animation, but doctors need cadavers to develop the needed skills. I bet my body would do a lot more good at some school than rotting in the ground or burned away.
I understand that but I also don't trust strangers to be respectful to my body. My family and I would rather my human suit rot in the ground as nature intended.
@@Friggsdottir that would imply you have no coffin
@@Friggsdottir the natural way would actually be your carcass being eaten by animals, insects and fungus....I dont think nature intended for us to forever rent out a plot of land so our body can rot inside a wooden box.

everyone's wondering why and how he has the head, but that part is obvious. I'm just curious at how it was cut in half so perfectly and cleanly. I'm curious how these body parts get dissected and preserved now
frozen and cut I think, if those plastination videos mean anything
Band saw
They take it to a construction site and use their skill saw
Hand saw
They have tons of expensive tools, I’m sure they use hand saws or something similar.
I just love this channel! Justin and Jonathan, you guys are brilliant. My 8 year old daughter even watches with intrigue and just finds the human body fascinating. Keep up the great work
This is very interesting I’ve just had really bad pneumonia while I was recovering from a operation, it’s fascinating to se exactly how it happened. Thanks for making these videos.
Aspiration pneumonia is not solely from aspiration of food and liquid. In actuality, the term is a blanket term to cover types of pneumonia that are not from a viral source. Think of the aspiration of food and liquid as the powder keg (consumable proteins and sugars) and aspiration of bacteria from the environment as the match. The bacteria thrive with the fertilizer in the warm, moist environment of the lungs.
But, this is only component of pneumonia. Not all people who have pneumonia aspirate, and not all people who aspirate get pneumonia. I've done countless of swallow x-rays on people with clear lungs. Your cardiopulmonary status, level of mobility, comorbidities, and overall physical health also play just as large of factors when it comes to getting pneumonia. I've had lots of patients with normal swallows who develop pneumonia after falling at home or after a major operation because they're not up and physically mobile like usual.
Hope you are better
@@kateclark7250 I am, Thankyou

Then you better make plans now to do so because after you’re dead, it’s not up to you anymore, unless you have specific plans that you paid for and had filed with authorities.
Make the arrangements TODAY, then. Tomorrow is not guaranteed to any of us.
It totally amazes me how the human body knows what it needs to function. I'm so amazed by this channel.❤
Considering my father died because of something going down the "wrong tube" I'd say that yes, it is pretty darn bad.... Three hospitals refused to even let us in because they thought he drank poison. And the doctors of the fourth one tried to do CPR(if you can call punching his chest repeatedly, no mouth to mouth CPR) but by then it was already to late.
Soooo they let him die and effectively killed him?
I am sorry for your loss. That is a horrible way to go. Also, chest punching was a cpr technique used in old wartime, we don't do it now because, we don't need to.
Sorry for your loss bro. I wish you the best. Rip to your father 🙏🏽
Im sorry for your loss, but aren't the hospitals that refused to take care of him liable for manslaughter or negligence?
@@jaztin7197 Unfortunately they aren't. Hospitals have the right to refuse patients for any reason. Most of the time it's one of two reasons - they're full and your condition is either not as serious as other patients or your condition is so serious that you are less likely to live than other patients, so they take them instead. And the other reason they refuse you is if ou require a risky surgery and the hospital doesn't want to be liable if a nurse screws up or you die anyway. This is the example where greed kills. Shocker.
