I wish you had complete physiology and anatomy for first med students :( . you r just too good . very audible . very entertaining .
😢😅😅 ,
The lion had me dying😂
Saying that the peritoneum is a fancy word for the abdomen is an unjustified overgeneralization. The peritoneum is a membrane that lines the abdomen, however some organs like the duodenum and kidneys sit outside of this membrane, hence the term "retroperitoneal organ"
This is glorious and so interesting, THANK-YOU, please don't stop making videos!
GREAT VIDEO! Thank you!
Why are you guys so helpful😭😭😭
Everything is just so easy to understand.
I can't thank you enough 🙏
Thank you, thank you, thank you.💕 💕
Loved it thank you so much
It was very useful ,thank u ❤
thank you, thank you, and thank you
Thank you very much
you are soooo funny, especially the lion part, hahahhaaa
Lol tour de abdomen that cracked me up
Retroperitoneum: pancreas, abdominal aorta, inferior vena cava
2:12 unencapsulated… a slurry of cells … the lion of the abdomen
Exocrine pancreas:
A) receives chime which is in gastric acid ska hydrochloride acid
B) HCO3 Bicarbonate releases
C) amylase: starch -> smaller carbs
D) lipase: breaks down triglycerides into glycerol (no fatty acids)
-ogen indicates an enzyme that is inactive
proteolytic: trypsinogen, chymotrypsinogen
-enteropeptidose breaks down and thereby activates -ogens
Activated trypsin breaks down proteins that break down: membrane
releases salts and enzymes
Peritoneum is not a fancy word for abdomen.
Is now lol
Exactly. I was really disappointed when I heard this. Almost stopped the entire video.
@@danielspizzy15 what is it then?
@@rannaghoremoumita926 its a massive sheetlike membrane that forms the lining of the cavity and many of the organs including the intestines.
@@danielspizzy15 I literally stopped the video and had to rewind lol. Overall khan academy has very helpful videos though
could you please make a video about exocrine glands ?
I'm guessing no one else noticed that he shaded the pancreas into the form of a lion, cause I actually thought that was pretty entertaining...
Yanelis Vargas I only figured out midway through, before I thought it was something else anatomical...
+khanacademymedicine hi there. There seems to be an error at 7:55. The enzyme that breaks down trypsinogen is actually ENTEROKINASE not ENTEROPEPTIDASE. Enteropeptidase actually breaks down peptide bonds. Completely different role. Please address this at your earliest convenience. Thank you.
Makes sense. Thank you for your reply.
MadGainsBro enteropeptidase breaks trypsinogen to trypsin in the duodenum, it's a duodenal enzyme
sorry i meant the activation of trypsinogen is either by trypsin or enteropeptidase
That really cleared that up for me, thanks man
Pancreas is secondary retroperitoneal, because it is behind the peritoneum but it also touches it by its one side...
🦁
What prevents the trypsin and chymotrypsin from working on proteins in the wall of the small intestine?
Nicholas Zuraw They are actually stored as trypsinogen and chymotrypsinogen (both inactive), and are activated by enteropeptidase and trypsin (respectively) in the brush border/lumen of the duodenum.
Nicholas Zuraw You have trypsin inhibitor protein which inhibits trypsin, you also have prostaglandin which protects the small intestine from the effects of acid in chyme and proteases. Furthermore they will eventually be inactivated via changes in pH
Is he saying that getting hit by a car can break a bond?
Can anyone give me any 2 differences between pancreatic juice and digestive juice ? Please it's very important to know for me
I'm sorry but there's a mistake at 4:21. What I have learnt before: the HCO3- is secreated by the Brunner glands - which locate in the submucousa layer of the doudenum. Pls Correct me if Im wrong. Thanks. Your Videos help me so much
I think it is secreted by the pancreas duct cells www.vivo.colostate.edu/hbooks/pathphys/digestion/pancreas/exocrine.html
You're both right
peritoneum is a fancy word for abdomen? huh?
Sir you mentioned that in a car accident a massive energy provided will activate trypsinogen and chymotrypsinogen which will break membrane protein or any else protein it find...so why nt in normal conditions?
I'm taking the pancreas lion as my profile picture
Rizqi Rizaldo bwahhhhhahaha
bro go straight to the point. i didn’t come here for fucking anatomy
can you tell my pancreas that it is supposed to work like THAT !?!? .... -.- It doesnt, destroyed my duodenum and nearly killed me because of that. :( .....
***** hope your okay :) Just tune your pancreas to work like the one in the video...power of the mind and all that
it seems my pancreas is deaf ... -.-
I don't get that "lion" picture - just don't see it
that lion looks like a turd on a leaf
Butt
