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.
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 😂😂
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)
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!
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 .
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 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!
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'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.
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).
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.
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
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
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
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
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.
As a former bulimic, I can confirm that the stomach can hold a gallon of food or more. In fact, I think it can hold 2-3 gallons of food, because I remember filling a five gallon bucket with vomit in two consecutive binges-purge session.
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.
Is it strange that I found this more fascinating than the Nebulae video on CrashCourse Astronomy? Actually this is one of the most fascinating videos I've ever seen from CrashCourse.
Hey Guys. Can you look into Gastroparesis? Not many doctors know about it, and no one really knows what causes it and it is very hard to treat. If anything it would help bring awareness to this sad and crazy disease. Thank you!

nice

Please never stop making more science videos.
I have a feeling Beaumont WAS the hunter!!
Very plausible....
loool XDD
what a plot twist
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
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!
What's the point in paying for college when you can learn more in 20 minutes than you learned in an entire semester.
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
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.
My mouth dropped after googling and finding out that the story between Sir Martin and Beaumont actually happened 😦
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 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.
I watched this while eating, it was a very weird experience.
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 😂😂
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

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 .
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.
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!
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 watched crash course for my degree 💀
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.

Hank Green is just awesome. ....God bless that guy

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
Dude i know its too late, but you just saved me. OMG 10x better than my lecturers!
John and Hank Green are my favorite Greens
Jimmy D Nah nothing compares to rachel green
Thank you for the laughs. You make education 'simple' and fun.
my human anatomy exam is in less than 4 hours and this has helped immensely
Part 1: mouth
Part 2: stomach
I do not like where this is going
the anas
Anus is the best part.
( ͡° ͜ʖ ͡°)
Great video. Pop ups don't stay long enough to read though in case they are imparting information that is relevant.
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 will tell my biology teacher about this wonderful channel. Maybe we can learn together with this.
No one cares
Oh, man. You guys should totally try to do a chemistry segment where you explain plastination preservation. That would be pretty cool!
These videos are so perfect! Please come be my teacher - watching these videos I learn so much more than going to class!
God Bless you guys ( especially Hank ! ) - I adore these Biology Videos :)!
I cracked up laughing at 9:48 lol!
You and Bozeman Science are my saving grace.
All of your videos are a great help!!!!!! love the animation you have!
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
I love these because they help with my tests
Brilliant!
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
That story just killed me
Is it wrong for me to salivste as I watch this video?
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 CZcams'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
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
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
GREAT WORK👍🏻💪🏻😱
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
Thanks for the video it was informative
the esophagus - 'is really just a glorified laundry chute lined with smooth muscle' 😂😂
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 LOVE these videos, PLEASE make more! These videos help me so much with AP Bio!
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**
Probably one of the most interesting videos out there ❤️❤️
i pity martin, but thanks to him for helping the science ♥️
thank the gods for crash course...lol
As a former bulimic, I can confirm that the stomach can hold a gallon of food or more. In fact, I think it can hold 2-3 gallons of food, because I remember filling a five gallon bucket with vomit in two consecutive binges-purge session.
7:50 Squid eyeballs? I would not be polite about that. "Get those eyeballs away from me!"
You are amazing. the way you explain is seriously super cool.
Thanks to the guy who shot St. Martin, im suffering in reviewing this gastic juices and other stuff
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.
Thank you for the Video! I'm learning a lot from your videos, great Job!
actually watched this while eating lunch. Great help!
Is it strange that I found this more fascinating than the Nebulae video on CrashCourse Astronomy? Actually this is one of the most fascinating videos I've ever seen from CrashCourse.
you make learning sooooo fun! Thank you!!
Thank you so much! I have a test on cells and the digestive system tomorrow. This has really helped me understand.
Much more helpful than my bio professor, thank you for getting me through nursing school
This is so good. So blown away by you guys! 😊😁
THESE ARE THE BEST VIDEOS EVER I LOVE YOU CRASHCOURSE
The story was so gross and awesome 😂
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.
man... I love crash course so much!
1/2 way thru this I wanted to rewatch Osmosis Jones. Thanks I think.
I love his sense of humor.
I'm eating a meal as I watch this 😂😂
Salivary amylase + starch = maltose
not glucose.
Technically it becomes glucose later when broken down by maltase.
Yea boi
U know about galactose
The beginning was awesome and interesting.
Thank you this really helps me crash course
Love the extra information about michigan too! im from michigan!

These videos are saving my life right now. Thank you
I was eating a grilled cheese sandwich while watching this, and had to pause when Hank mentioned it XD
I freaking LOVE this guy
Past scientist just always rock my socks off.. Yes sir..
cool stuff. these vids r helping me with my gcse even though I am in year 10
thankyou so much 💓
Haaha i loved the wayhe explained the story about st martin .. 83 years old and still alive :D
i would alos like to say thank you for all the work you put into making the video and flashcards
Hey Guys. Can you look into Gastroparesis? Not many doctors know about it, and no one really knows what causes it and it is very hard to treat. If anything it would help bring awareness to this sad and crazy disease. Thank you!
Could you make an episode about heart burns? It would be very fitting.
TFW this is actually really helpful in helping me study for GI block lol
This video is more than I can digest
I found a typo! It says you're gastric secretions at 8:35 :) I've been watching crash course forever and this is the first time I've noticed one!
Hi Hank, I was born at William Beaumont Hospital in Royal Oak Michigan just outside Detroit. I never heard this story about him. Thanks for the Info.
Beaumont hospitals are popular in michigan and theres even a medical school named after him!
