Term
|
Definition
LIVER: produces bile
GALLBLADDER: stores and secretes bile
bile is alkaline fluid that aids in digestion |
|
|
Term
|
Definition
-bile travels from the liver to the gallbladder and then to the small intestine, where it assists digestion.
-In the small intestine, most of the bile is reabsorbed and sent back to the liver for reuse.

Term
Digestion and Absorption in small intestine |
|
Definition
small intestine digests:carbs, fats, proteins
most absoprtion occurs here |
|
|
Term
Role of HCL and Pepsin (found in stomach) |
|
Definition
HCL: unfolds protein and stop salivaryamylase action, prepares protein for digestion
PEPSIN: begins protein digestion |
|
|
Term
Gastrin(in stomach)
&
Secretin |
|
Definition
GASTRIN:hormone
-stimulates gastric secretion and movement
-increases motility in the stomach and stimulates the release of HCl and pepsinogen which promotes protein digestion
SECRETIN: released in the duodenum in response to incoming chyme and reduces gastric secretion and motility, so it has an opposite effect to gastrin

|
Term
Cholecystokinin (CCK) (in GI tract) |
|
Definition
is released by cells in the small intestine and stimulates the pancreas to secrete digestive enzymes and the gallbladder to release bile and it slows down gastric emptying
|
|
|
Term
Gastric Inhibitory Peptide (GIP) (found in GI tract) |
|
Definition
is released by cells in the small intestine in response to fat and glucose and inhibits gastric secretion, motility, and emptying
stimulates the release of insulin
