Solution
The correct option is D Secretin
Secretin, gastrin and cholecystokinin are secreted by the endocrine cells of the gastrointestinal tract. Secretin acts on the exocrine (glands with ducts) part of the pancreas and stimulates the secretion of water and bicarbonate ions.
Gastrin stimulates the stomach to secrete gastric juice. Gastrin acts on gastric glands present in the stomach and stimulates the secretion of hydrochloric acid and pepsinogen.
Cholecystokinin stimulates the secretion of pancreatic enzymes and bile juice by gallbladder.
Enterogastrone is secreted by mucosa of duodenum of the small intestine. It inhibits gastric secretions and movements.
