Hormones or paracrines that inhibit gastric secretion include ________.

const2013 [10]

The correct answer is: D) secretin

Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:

Cephalic-by the brain

Gastric-by the stomach itself

Intestinal- by the small intestine

All of three can work simultaneously.

Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.
