Definition


Gastric acid is one of the components responsible for digestion in the stomach and one of the elements, with other enzymes, that make up gastric juice. This is a hydrochloric acid solution produced by the cells that make up the lining of the stomach. Gastric acid reduces the size of digested foods in the stomach, enabling them to take a digestible form for the organism. During digestion, gastric acid eliminates a large number of bacteria. A lack of gastric acid can expose the organism to infection. Gastric ulcers can be caused by an over-production of gastric acid.
