Pepsinogen →Pepsin
|
chief cells in stomach - digests proteins
Gastrin and distention of stomach stimulates ANS to release |
Gastrin and distention of stomach stimulates ANS to release
|
|
|
HCl acid
|
parietal cells of the stomach fundus (t. mucosa) - activates pepsin, barrier against microorganism
Gastrin and distension of stomach stimulates ANS to release |
Gastrin and distension of stomach stimulates ANS to release
|
|
|
Gastrin
|
Gastric glands in the gastric pits of the t.mucosa - stimulates secretion of HCl and promotes releaste of release of gastric gland products
Distension of stomach, extension of rugae trigger gastrin release. and, contraction of smooth muscle in t.mucosa |
Distension of stomach, extension of rugae trigger gastrin release. and, contraction of smooth muscle in t.mucosa
|
|
|
Secretin
|
Crypt of Lieberkün - cause the release of sodium bicarbonate salts in the presence of acidic chyme. close the pyloric valve.
arrival of acidic chyme in duodenum |
arrival of acidic chyme in duodenum
|
|
|
sodium bicarbonate salts
|
exocrine portion of pancrease - neutralizes acid chyme
secretin |

CKP
|
Crypts of Lieberkün - stimulates pancrease to release enzymes for lipid and protein digestion. Stimulates gallbladder to contract to release bile for emulsifying fats
distention of sm. intestine and lipid- and protein- rich chyme in duodenum |
distention of sm. intestine and lipid- and protein- rich chyme in duodenum
|
|
|
bile
|
hepatocytes of liver - emulsifying agent necessary for breaking down lipids, bilirubin and fatty acids, aids in absorption of fat soluble vitamins
CKP cause gallbladder to contract and release bile. Continuously produced. Stored and concentrated (up to 15 times) in gallbladder). |

Sm. Intestine Enzymes
|
Crypt of Lieberkün - along w/ pancreatic enzymes and bile
distension of small intestine due to chyme active parasympathetic nervous system of autonomic nervous system to stimulate Crypt of Lieberkün |
