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"

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?
@MrJarmach
@MrJarmach 9 лет назад
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.
@kylehallas2011
@kylehallas2011 9 лет назад
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

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

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?

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

@moosethephysio

+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.
@moosethephysio

MadGainsBro enteropeptidase breaks trypsinogen to trypsin in the duodenum, it's a duodenal enzyme
@aimanpourahmari113
@aimanpourahmari113 7 лет назад
