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 release is also stimulated by the stretching of the stomach walls during a meal, the presence of certain foods (particularly proteins) within the stomach cavity and an increase in the pH levels of the stomach (i.e. the stomach becoming less acidic).

Detailed explanation-3: -During the cephalic and gastric phases of a meal, gastric acid secretion is stimulated through the release of gastrin.
