Answer:
CCK
Step-by-step explanation:
CCK is an acronym for Cholecystokinin hormone. This hormone is very important in the digestion process. Its importance is because after being secreted by small intestinal mucosal epithelial cells, cholecystokinin controls the release of bile from the gallbladder and stimulates the production of digestive enzymes.
In addition to being produced and distributed by small intestine epithelial cells, this hormone can also be produced and distributed in the brain.
