Stimulates hcl secretion by parietal cells
WebThe three stimulants of gastric acid secretion likely to have physiological roles in regulation of secretion are acetylcholine, gastrin, and histamine. Acetylcholine is released by vagal and intramucosal reflex stimulation, acting directly on the parietal cell. Gastrin is released by peptides and fr … Regulation of gastric acid secretion WebA) Stimulates parietal cells to secrete HCl B) Stimulates chief cells to secrete pepsinogen C) Stimulates secretion of pancreatic juice enzymes D) Maintains structure of gastric …
