Answer:
c. increase the release of digestive enzymes and bile
Explanation:
Secretin and cholecystokinin are hormones produced in the duodenal region of the small intestine. They are both involved in the release of digestive enzymes and bile.
Secretin is actively involved in controlling the pH of the chyme when it enters the duodenum from the stomach. It does so by inhibiting the release of gastric acid from the parietal cells in the stomach. Secretin induces the release of sodium bicarbonate ions from the pancreas which help to increase the pH of the chyme. This hormone also stimulates the secretion of bile.
Cholecystokinin (CCK) stimulates the contraction of the gallbladder and the release of bile into the duodenum. CCK also acts on the pancreas, stimulating it to produce pancreatic juices for digestion.
