GENERAL HISTOLOGY

Detailed explanation-1: -Cholecystokinin is a hormone produced in your small intestine. It plays a fundamental role in the digestive process. When fats and proteins enter your small intestine, cholecystokinin triggers your gallbladder and pancreas to contract.

Detailed explanation-2: -Cholecystokinin (CCK) is the major hormone responsible for gallbladder contraction and pancreatic enzyme secretion. CCK, like other gastrointestinal hormones, is produced in discrete endocrine cells that line the mucosa of the small intestine [1].

Detailed explanation-3: -When stimulated by the hormone cholecystokinin (CCK), the gallbladder contracts, pushing bile through the cystic duct and into the common bile duct.

Detailed explanation-4: -The major nutrients that stimulate CCK release are fats and ingested proteins. Of these, the specific meal components that cause CCK release include fatty acids and amino acids. In some species, proteins appear to stimulate CCK secretion by virtue of their ability to inhibit intralumenal trypsin activity (20, 31).

Detailed explanation-5: -The most recognised functions of this hormone are in digestion and appetite. It improves digestion by slowing down the emptying of food from the stomach and stimulating the production of bile in the liver as well as its release from the gall bladder.
