Hydrochloric acid (HCl) secretion assists protein digestion by activating pepsinogen to pepsin, renders the stomach sterile against orally-ingested pathogens, prevents bacterial or fungal overgrowth of the small intestine, encourages the flow of bile and pancreatic enzymes, and facilitates the absorption of a variety of nutrients, including folic acid, ascorbic acid, beta-carotene, non-heme iron, and some forms of
Then the antrum (lower stomach) contracts rhythmically, mixing the food with acid and enzymes (stomach juices) and grinding the food down into small pieces so that it is more easily digested. The cells lining the stomach secrete three important substances: mucus, hydrochloric acid, and the precursor of pepsin (an enzyme that breaks down proteins).
Symptoms of indigestion are often mistaken for excessive gastric acid.
