The primary source of acid in the stomach is parietal cells, which secrete hydrochloric acid (HCl). This acid plays a crucial role in the digestive process by breaking down food, activating digestive enzymes, and providing an acidic environment that helps kill harmful bacteria. The production of stomach acid is primarily regulated by the hormone gastrin, which is released in response to food intake, along with neural signals and other factors like histamine.
