where is Gastrin secreted from
stomach
actions of Gastrin
- stimulates gastric secretion and motility
- stimulates ileal motility and relaxes ileocecal sphincter
- stimulates mass movement of colon
Stimuli for Gastrin secretion
- proteins and protein digestion products in stomach
- distension of stomach
- parasympathetic input to stomach
where is Cholecystokinin (CCK) secreted from
secreted from duodenum and jejunum
Actions of cholecystokinin (CCK)
inhibits gastric secretion and motility, potentiates actions of secretin on pancreatic bicarbonate secretion, stimulates pancreatic enzyme secretion, stimulates bile secretion by live, stimulate gallbladder contraction and relaxation of sphincter of Oddi
stimuli for Cholecystokinin (CCK) secretion
Fats or protein digestion products in duodenum
where is Secretin secreted from
secreted from duodenum and jejunum
actions of Secretin
inhibits gastric secretion and motility, stimulates pancreatic bicarbonate secretion, potentiate actions of CCK on pancreatic enzyme secretion, stimulates bile secretion by liver
stimuli for Secretin secretion
Acid in duodenum
where is Glucose-dependent insulinotropic peptid (GIP) from
secreted from duodenum and jejunum
actions of Glucose-dependent insulinotropic peptid (GIP)
- inhibits gastric secretion and motility
- stimulates insulin secretion by pancreas
stimuli for Glucose-dependent insulinotropic peptid (GIP) secretion
glucose, fats, or acid in duodenum; distension of stomach
