THORAX ABDOMEN AND PELVIS

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: -CCK mediates digestion in the small intestine by inhibiting gastric emptying. It stimulates the acinar cells of the pancreas to release a juice rich in pancreatic digestive enzymes (hence an alternate name, pancreozymin) that catalyze the digestion of fat, protein, and carbohydrates.

Detailed explanation-3: -CCK stimulates pancreatic secretion through hormonal and neuronal pathways. CCK is released from I cells of the small intestine and diffuses into the blood stream where it is carried to the pancreas. CCK binds to receptors on acinar cells to stimulate pancreatic enzyme secretion.
