Question

The hormone, secreted by the intestinal mucosa of the duodenum, that stimulates the GALLBLADDER to release bile is:

1) Insulin
2) Glucagon
3) Cholecystokinin
4) Gastrin

Answer 1

Cholecystokinin (CCK) is the hormone secreted by the intestinal mucosa of the duodenum that stimulates the gallbladder to release bile.

Step-by-step explanation:

The hormone secreted by the intestinal mucosa of the duodenum that stimulates the gallbladder to release bile is cholecystokinin (CCK).

Cholecystokinin (CCK) is released in response to the presence of proteins and fats in the duodenum. It stimulates the gallbladder to contract and release bile into the duodenum, which aids in the digestion and absorption of fats.
