Gastrin action
increse Gastric H+ secretion,Stimulates growth of gastric mucosa
Gastrin origin
G cells of the stomach
Gastrin stimulus
Small peptides and amino acids, Distention of the stomach,
vagal stimulation
Cholecystokinin (CCK) action
increase Pancreatic enzyme secretion, increase Pancreatic HCO - secretion,Stimulates contraction of the gallbladder and relaxation of the sphincter of Oddi ,Inhibits gastric emptying
Cholecystokinin (CCK) ORIGIN
I cells of the duodenum and jejunum
Cholecystokinin (CCK)STIMULUS
Small peptides and amino acids,Fatty acids
Secretin action
decrease Gastric H+ secretion, Inhibits trophic effect of gastrin on gastric mucosa, increase Pancreatic HCO - secretion, increase Biliary HCO - secretion 3
Secretin ORIGIN
