What hormones signal the release of bile and why?

Fatty acids in the lumen of the duodenum stimulate endocrine cells to release the hormone cholecystokinin (CCK). CCK stimulates contractions in the smooth muscle of the gallbladder. read more

Bile is formed in the liver and stored in the gall bladder. It is released into the first portion of the small intestine (duodenum) via the common bile duct in response to the hormone cholecystokinin (CCK) which comes from the Greek chole, “bile”; cysto, “sac”; kinin, “move”.
