Question

Which secretion are secreted by intestinal wall?explain their role in digestion of food

Answer 1

Explanation:

Endocrine cells secrete cholecystokinin and secretin. The most important factor for regulating secretions in the small intestine is the presence of chyme. This is largely a local reflex action in response to chemical and mechanical irritation from the chyme and in response to distention of the intestinal wall.
