Detailed explanation-1: -Gastrin is a peptide hormone primarily responsible for enhancing gastric mucosal growth, gastric motility, and secretion of hydrochloric acid (HCl) into the stomach. It is present in G cells of the gastric antrum and duodenum.
Detailed explanation-2: -Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas.
Detailed explanation-3: -The surface mucous cells secrete a layer of mucus that protects the stomach lining. Parietal cells secrete hydrochloric acid that helps break down food and intrinsic factor that aids in the absorption of vitamin B12. Chief cells secrete enzymes that support digestion.
