I love your work....it helps me a lot...but I have a suggestion....it would be really nice if u could talk a little slower... thanks for these nice videos....😊
Do I get participatory points for being home sick with a stomach bug when I watched this video? All your assumptions about whether the viewers had just regurgitated were unfortunately wrong in my case.
So gunwounds can lead to medical breakthroughs? Please don't tell those organisations in the US opposed to gun control. They're being annoying enough as it is, even to someone who isn't from the US...
oh yeah sure, let the massacres happen, someday we'll discover how poop is created, especially since we still have the same knowledge and skills in medecine as they had centuries ago. Sorry to point out how stupid your comment is
I could learn to be a rocket scientist with this guy as my teacher. You have the best method of teaching I have experienced thus far. Please never stop making more science videos.
It’s 2019(I’m aware this was posted a while ago), and I’m using this to help me with my science project and I just want to thank you for making these high quality videos that help educate people.
Great video! Just a single correction I would do: Gastrin (6:55) is excrated in the blood, not in the stomach itself (gastrin is a hormon after all, not an enzyme)
Um... yeah. If someone was that desperate to find me they could without the comment. It’s not like I said what floor I work on and the hours I’m there. It’s a BIG hospital with lots of security. Plus there are 3 Beaumont’s in Troy so come find me 😂😂
In my language (which is Dutch) we also use the word "bolus", but here it means turd... So the same word, but for the thing that comes out of your digestive system, and not for what goes in it. At least I hope... o.O
My digestive system is interesting. I've had chronic constipation since the age of three, and recently my number twos got drastically softer than usual, and my blood tests showed as if there was something wrong with my liver. I found out from a nurse (my mom) and a doctor we know, that it might be vitamin d deficiency. I got wonderfully skinny (waist circumference 81 cm) and started taking vitamin d regularly. it was really funny! I thought I was dying of liver cirrhosis and had to stop my favorite pastime (student parties) and it was just me forgetting to eat my vitamin d pills. Once I took my vitamins, my poop became harder and brown again. I actually found out what this whole poop shenanigan was, thanks to Hank and SciShow!
Im wondering why vomiting can be caused by a miscommunication in the brain, like how car sickness is caused by your body saying "I'm sitting still" and your visual cortex saying "were on the move" I'm guessing it's an adaptation to poisons? Poisons can cause miscommunication therefor the body will try remove them from the body. I'm just speculating if anyone has a definitive answer please let me know
Its not necessarily a miscommunication, its more just your body is getting ready for the fight/flight and so what happens is you don't want stuff in your stomach being digested and potentially using up energy that could be used in your fight/flight
dude I study medicine and when I first clicked on this video I thought "Oh well it's just a cartoon thing - it can't be that detailed" and I was amazed by all the things he said: It's all correct and so detailed and just on a really high niveau of education while explainig it very simple :D
8:33 - "If you are super anxious, [...] you're sympathetic nervous system will also inhibit gastric secretion [...]" "You're" instead of "your" in scishow? Woah.
+Kehla Martri It wasn't clear, because my resolutions not very good today, but I think it also had effect (noun) where it should have been affect (verb).
Very nice explanation of digestion . Thank you so much CRASH COURSE . You teach very well Hank . In a 10 minute video , all main concepts are explained .
Was anyone else eating and watching this and then became extremely aware of what your tongue and mouth were doing?...ya I don't know how to eat anymore :P
Bryan Cotto But Hank... oh my God, he just rambles on before the intro even plays, EVERY TIME. Every time while everyone else (That I watch on CC) just says a short thing, like a pun or short bit of info for 10-20 seconds and then let the intro play, then get to the point. Hank, though... HE JUST GIVES AN ENTIRE SUMMARY AND SPEECH BEFORE IT STARTS! XD
Thanks a lot! Sir your videos make it so much easier to learn such complex topics. I'm in class 8 now but I still can understand it quite well. Kudos to you and your team!!!
I know that we french-canadians have tough stomachs...after all we gave the World poutine...and poutine with fried chicken...and poutine with bacon...and poutine pizza, but COME ON!
+Cynthia Sonier well the chinese would like to have a word with french-canadians.. after all, they eat alot of questionable things like fried rotten tofu..
+Cynthia Sonier I am sorry, but I just cannot resist challenging the poutine with something requiring an even stronger stomach. I think any Southeast Asian who eats balut (I suggest looking up the term before finding the image.) might have tougher stomachs than French-Canadians. Feel free to disagree!
I have to admit that more than once I have laughed whilst swallowing and had food move up into my nasal cavity instead of down my gullet. Resultantly, I had a large lump of in digested bread come out of my nose a few hours later. Sorry to gross you out, but just saying that it can happen. The pallet isn't always working as it should :/ for me, anyways ;3;
8:35 is why IBS can be so problematic for some people. Stress makes me feel like I'm being stabbed in the gut, I have to spend hours on the toilet and eat only bland things. It's not fun, I'm glad I'm now taking anxiety medicine.
Crash course is going so well I have watched crash course biology 😍😍😍😍 it helped me a lot to clear my tests n now A &P is equally fantastic Hank Green is just awesome. ....God bless that guy
I just started watching this channel today to learn more about the digestive system, due to some recent medical issues I've had. This guy is so funny. I'm gonna keep going. Thank you!
Oh my bloody god @ the 08:32 your vs you're. I thought this was my favorite EDUCATIONAL channel, not one where the one single most appalling error feels at home.
If your nervous your sympathetic nervous system will inhibit gastric secretion was the biggest take away for me. I remember when I was younger id get nervous/anxious in certain situations and loose all my appetite and suddenly my bowels/bladder felt like they had to get rid of everything in my body. Was really SHIT.
6:11 lol. I love how they animated a chicken leg inside his coffee cup. This video reminds me of fistulated cows that are used to study their digestion.
I'm loving this subsection of a&p. My physiology class didn't go into much detail, and I love the digestive system. I do wish the lack of knowledge about vomit was acknowledged.
Crash course, I was wondering if you had like a basic summary of the whole digestive system or any other systems, because I am taking down notes. Thank you

nice
What's the point in paying for college when you can learn more in 20 minutes than you learned in an entire semester.
I watched this WHILE eating dinner...
I REGRET NOTHING!!!
These videos are half the reason I have an A in Anatomy 2! Thanks Hank!
I watched crash course for my degree 💀
Oh, man. You guys should totally try to do a chemistry segment where you explain plastination preservation. That would be pretty cool!
Great video. Pop ups don't stay long enough to read though in case they are imparting information that is relevant.
All of your videos are a great help!!!!!! love the animation you have!
And St. Martin and Beaumont lived on Mackinac Island! I went to the Beaumont museum in 5th grade. Pretty much everyone else found it disgusting.
THESE ARE THE BEST VIDEOS EVER I LOVE YOU CRASHCOURSE
i would alos like to say thank you for all the work you put into making the video and flashcards
Yay, French-Canada (otherwise known as Quebec). I'm watching from over there.
I love your work....it helps me a lot...but I have a suggestion....it would be really nice if u could talk a little slower... thanks for these nice videos....😊
Diya Saji on UA-cam they have a setting that you can change so he can talk slower.
crash course is AWESOME
This is it, Chief Cells
G-cells? like DG-cells?... as in Dark Gundam cells!?
THIS EPISODE OF CRASH COURSE WAS MADE WITH THE HELP OF KYOJI!!!!!!!!!!!!!
Thank you so much! This got me an A on my bio report:))) so helpful
Thank you. You guys rock
Cookies are coming maybe u want to prepare yourself !!😂😂😂
all this digestive talk is making me hungry *drools*
lymphatic system next please :(
At 1:26 does anyone else notice cloggsworth
Bowman same guy whose name is in nephron right? (Bowman's capsule)
i thought the entroendocrine cells were in the small intestines? entro is greek for intestinal... but why is it mentioned in the stomach instead???
will there be new history vids?
how did he sleep at night? on his back, presumably
question why do some people make a sound when they eat or drink
I threw up in the second grade in school. Throwing up isn't fun ;-;
Does anyone have a good diagram of the mouth?
Do I get participatory points for being home sick with a stomach bug when I watched this video? All your assumptions about whether the viewers had just regurgitated were unfortunately wrong in my case.
you gotta be kidney me, he got a shot! after that he had a hole (y) stomach which led to many discovarteries.
7:33 Brain monocle
MMM nachos and spit. lol
The intros are getting pretty long. And Hank was right, it did trigger my gag reflex.
PETITION TO MAKE HIM STOP SAYING CREAMY PASTE
Why do all of so very well began CRash Course stories end up with somebody being killed or threatend %)
So gunwounds can lead to medical breakthroughs? Please don't tell those organisations in the US opposed to gun control. They're being annoying enough as it is, even to someone who isn't from the US...
oh yeah sure, let the massacres happen, someday we'll discover how poop is created, especially since we still have the same knowledge and skills in medecine as they had centuries ago. Sorry to point out how stupid your comment is
+Robert Faber I'm sure that St. Martin really disagrees that a gun can cause more good than harm. The dude had a hole in his stomach.
ChBro20 You do realise that what you're saying is exactly my point, right, except with less cynicism?
+ChBro20 yooo you a peaaaak geeza
+Robert Faber oh my bad then, still need to master the skill of reading UA-cam comments.
I have a feeling Beaumont WAS the hunter!!
Very plausible....
loool XDD
what a plot twist
I could learn to be a rocket scientist with this guy as my teacher.
You have the best method of teaching I have experienced thus far.
Please never stop making more science videos.
I watch crash course for my exams
me too
Me too
i watch for homework
me rn lol
I'm writing physiology of the digestive system in two days and this is all I'm going to study. Wish me luck
This dude is legit. even 8 years later in 2024.
St. Martin had a holy (hole-y) stomach. He's now the patron saint of the digestive system, the internet and all other tubes everywhere.
+TheFireflyGrave Holey Coral. Holey.
+TheFireflyGrave You've done good work here.
-Nicole
CrashCourse NOTICE ME NICOLE SENPAI! NOTICE ME!
TheFireflyGrave lol.love it
This video is more than I can stomach.
+Nathan Fales This stomach is more than I can bacon.
Wait that doesn't make sense.
Wait actually it kind of does.
+Nathan Fales - You gotta be kidney me. These puns are hard to swallow.
+Nathan Fales MY QUEST IS AT AN END. Looking for the pun comment in this video.
Ben Aaron 😂😂GOOD ONE
this comment section is more than i can digest
My mouth dropped after googling and finding out that the story between Sir Martin and Beaumont actually happened 😦
I watched this while eating, it was a very weird experience.
I'm a medical student and after every lecture I always come here to understand better. You're the best!! Literally wouldn't pass my tests without you!
It’s 2019(I’m aware this was posted a while ago), and I’m using this to help me with my science project and I just want to thank you for making these high quality videos that help educate people.
Part 1: mouth
Part 2: stomach
I do not like where this is going
the anas
Anus is the best part.
( ͡° ͜ʖ ͡°)
Is it wrong for me to salivste as I watch this video?
So how does St.Martin take a shower
Now we're asking the real questions.
Right?? That's hard enough to do with a plaster cast on your arm, let alone a gaping hole in your... well, in _you_!
Isn't that hard; you literally have a doctor as your servant.
How did he do a lot of things??? Like sleep on his back or torso without stomach acid getting all over the sheets.
Brendan Phares he sounds like a legend to me!
Great video! Just a single correction I would do: Gastrin (6:55) is excrated in the blood, not in the stomach itself (gastrin is a hormon after all, not an enzyme)
Is a "hormon" like a hormonal Mormon?
YOU DARE CORRECT CRASH COURSE
First year at uni this is my only revision tool
Sending you blessings from second year at uni
1st year.
Am i too late?
3rd year of high school here. How's uni going?
@@Aphelia. y u even need this info in highschool
@@animeandstuff5377 what do you think we learn at high school????
My parents met while working at, and I and my brother were both born at, William Beaumont Hospital in Royal Oak, Michigan.
I went to a school named after St Martin... it was a different St Martin, but still...
I work at Beaumont in Troy!!
Um... yeah. If someone was that desperate to find me they could without the comment. It’s not like I said what floor I work on and the hours I’m there. It’s a BIG hospital with lots of security. Plus there are 3 Beaumont’s in Troy so come find me 😂😂
In my language (which is Dutch) we also use the word "bolus", but here it means turd... So the same word, but for the thing that comes out of your digestive system, and not for what goes in it. At least I hope... o.O
+Sjoerd Wennekes the mor eu know
If anyone wants more about St Martin and Beaumont, there is a Sawbones episode about it labeled The Gut Hole Romance. It's incredibly interesting.
My digestive system is interesting. I've had chronic constipation since the age of three, and recently my number twos got drastically softer than usual, and my blood tests showed as if there was something wrong with my liver. I found out from a nurse (my mom) and a doctor we know, that it might be vitamin d deficiency.

Its not necessarily a miscommunication, its more just your body is getting ready for the fight/flight and so what happens is you don't want stuff in your stomach being digested and potentially using up energy that could be used in your fight/flight
You've pretty much hit it spot on. Your body hasn't caught up to modern times so it still assumes all miscommunication is from poison
dude I study medicine and when I first clicked on this video I thought "Oh well it's just a cartoon thing - it can't be that detailed" and I was amazed by all the things he said: It's all correct and so detailed and just on a really high niveau of education while explainig it very simple :D
Unless Hank presents it, I don't watch because it is not so interesting. It's like watching Big Bang Theory without Sheldon.😁😁😁
8:33 - "If you are super anxious, [...] you're sympathetic nervous system will also inhibit gastric secretion [...]"
"You're" instead of "your" in scishow? Woah.
+Kehla Martri It wasn't clear, because my resolutions not very good today, but I think it also had effect (noun) where it should have been affect (verb).
Woo! Somebody beat somebody to something!
+Roberta Tallienne Better than beating something to somebody if you catch my drift ;)
I actually don't. Is it something sexual?
Roberta Tallienne y-yes... nevermind
This video is more than I can stomach.
Very nice explanation of digestion . Thank you so much CRASH COURSE . You teach very well Hank . In a 10 minute video , all main concepts are explained .
How can you keep a hole open? Shouldn't the acid spill out
I imagine that they plugged it up somehow
no
It did at times. If I remember correctly, he couldn't sleep laying flat.
Was anyone else eating and watching this and then became extremely aware of what your tongue and mouth were doing?...ya I don't know how to eat anymore :P
Againnnnn, the intro played a quarter way into the video. GOD DAMN IT, HANK!
+Mac Was Pfff... Watch CC Psychology. A few episodes have intros that are almost HALF the episode.
That happens to me in other videos but didn't happen in this one, I think that is UA-cam's fault. But who is Hank?
Bryan Cotto But Hank... oh my God, he just rambles on before the intro even plays, EVERY TIME. Every time while everyone else (That I watch on CC) just says a short thing, like a pun or short bit of info for 10-20 seconds and then let the intro play, then get to the point. Hank, though... HE JUST GIVES AN ENTIRE SUMMARY AND SPEECH BEFORE IT STARTS! XD
Osiris 12
It's the dude talking in this video... O_O
I see what you mean... I didn't mind it
Thanks a lot! Sir your videos make it so much easier to learn such complex topics. I'm in class 8 now but I still can understand it quite well. Kudos to you and your team!!!
holy shit how can you keep a hole open on your body?? doesn't the blood keep spilling?? just imagining it creeps me out and makes me wanna puke
I would assume that the muscles and blood vessels healed after a short time.
Fun fact, Pepsi is named after pepsin, because the idea was it would help with digestion.
I know that we french-canadians have tough stomachs...after all we gave the World poutine...and poutine with fried chicken...and poutine with bacon...and poutine pizza, but COME ON!
+Cynthia Sonier well the chinese would like to have a word with french-canadians.. after all, they eat alot of questionable things like fried rotten tofu..
FUCK THAT SHIT us qubecers DO NOT HAVE FAST IMMUNE SYSTEMS !!
+Cynthia Sonier How about the eskimos and the swedes with their surstromming?
+Cynthia Sonier I am sorry, but I just cannot resist challenging the poutine with something requiring an even stronger stomach. I think any Southeast Asian who eats balut (I suggest looking up the term before finding the image.) might have tougher stomachs than French-Canadians. Feel free to disagree!
+Asummersdaydreamer14 It is likely that the definition of "strong stomach" is different between you and Cynthia!!
I cracked up laughing at 9:48 lol!
I have to admit that more than once I have laughed whilst swallowing and had food move up into my nasal cavity instead of down my gullet. Resultantly, I had a large lump of in digested bread come out of my nose a few hours later. Sorry to gross you out, but just saying that it can happen.

it helped me a lot to clear my tests n now A &P is equally fantastic
Hank Green is just awesome. ....God bless that guy
God Bless you guys ( especially Hank ! ) - I adore these Biology Videos :)!
I just started watching this channel today to learn more about the digestive system, due to some recent medical issues I've had. This guy is so funny. I'm gonna keep going. Thank you!
Thank you for the laughs. You make education 'simple' and fun.
Dude i know its too late, but you just saved me. OMG 10x better than my lecturers!
Oh my bloody god @ the 08:32 your vs you're. I thought this was my favorite EDUCATIONAL channel, not one where the one single most appalling error feels at home.
You were really trying to make us sick with this one, weren't you? XD
The soda cans full of saliva are what got to me... **gurggle**
how he could stay alive while his stomach was opened?:"
Because stomach is not vital organ and besides the bacterias are killed by hcl entering the stomach
Whoop whoop. Who is here for bio finalssss
That story just killed me
I’m eating chips right now...
If your nervous your sympathetic nervous system will inhibit gastric secretion was the biggest take away for me. I remember when I was younger id get nervous/anxious in certain situations and loose all my appetite and suddenly my bowels/bladder felt like they had to get rid of everything in my body. Was really SHIT.
Alexander Sandalis Same here😁😂
I will tell my biology teacher about this wonderful channel. Maybe we can learn together with this.
No one cares
Why does my mouth water when I see a girl I like? She isn't food
(this is just a joke not be taken seriously. Don't assume gender)
she's a snack
hey - can u make one about periods/ovulation? i need to know what is happening in my body atm and you are my fav source of body information
John and Hank Green are my favorite Greens
Jimmy D Nah nothing compares to rachel green
I work at Beaumont Hospital.... hmmm is this where the name came from???
Beaumont shot that dude.
6:11 lol. I love how they animated a chicken leg inside his coffee cup.
This video reminds me of fistulated cows that are used to study their digestion.
GREAT WORK👍🏻💪🏻😱
I'm loving this subsection of a&p. My physiology class didn't go into much detail, and I love the digestive system. I do wish the lack of knowledge about vomit was acknowledged.
That is A LOT of nachos...
Mixed with spit.
~Hank Green 2015
I like how st Martin never wore a shirt post gunshot wound
Thanks for the video it was informative
Do not mind but healthy saliva is slightly alkaline not acidic
Crash course, I was wondering if you had like a basic summary of the whole digestive system or any other systems, because I am taking down notes. Thank you
The story was so gross and awesome 😂
Lol, I'm watching this to catch up in health class while I'm sick and feeling nauseous. But don't worry, I didn't barf.
You are amazing. the way you explain is seriously super cool.
