Detailed explanation-1: -Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. Acidic gastric juice is found in all vertebrates, and its main function is to inactivate microorganisms.
Detailed explanation-2: -The antrum of the stomach contains pyloric glands, and their main feature is the presence of gastrin-secreting G cells. Somatostatin-secreting D cells are present in the pyloric and oxyntic glands and modulate gastrin release and gastric acid secretion [1].
Detailed explanation-3: -The stomach secretes gastric juice, which contains hydrochloric acid.
Detailed explanation-4: -Acid is secreted by parietal cells in the proximal two thirds (body) of the stomach. Gastric acid aids digestion by creating the optimal pH for pepsin and gastric lipase and by stimulating pancreatic bicarbonate secretion.
