cholecystokinin
Bilirubin is used by the liver, to make bile
This is a digestive hormone released with secretin when food from the stomach reaches the first part of the small intestine. It is made by some of the cells lining the first part of the small intestine.
Cholecystokinin is the hormone that causes the gall bladder to release stored bile. It is made in the small intestine and secreted when fatty food goes from the stomach into the small intestine.
The sphincter of Oddi regulates the passage of pancreatic juices and bile into the duodenum of the small intestine.
Cholecystokinin
progesterone.
The small intestine is where most chemical digestion takes place. Most of the digestive enzymes that act in the small intestine are secreted by the pancreas and enter the small intestine via the pancreatic duct. The enzymes enter the small intestine in response to the hormone cholecystokinin, which is produced in the small intestine in response to the presence of nutrients. The hormone secretin also causes bicarbonate to be released into the small intestine from the pancreas in order to neutralize the potentially harmful acid coming from the stomach.
It is a hormone produced by stomach.Itg stimulates secretion of gastric juice.
because of it low pH(making it acidic), the duodenum (the first section of the small intestine) secretes cholecystokinin (CCK), which causes the gallbladder to secrete bile.
Sometimes, the pituitary gland keeps on secreting the triggering hormone. this causes post puberty hyper secretion.
Renin which causes the production of Angiotensin which ultimately is converted into Angiotensin II.
