stomach
stomach J-shaped organ, lying to the left and slightly below the
diaphragm in human beings; one of the organs of the
digestive system. At its upper end, it connects to the gullet (
oesophagus), and at the lower end to the
small intestine. The stomach itself is lined by three layers of muscle and a folded mucous layer that contains gastric glands. These
glands secrete hydrochloric acid that destroys some food bacteria and makes possible the action of pepsin, the
enzyme that digests
proteins. Gastric gland secretion is controlled by the sight, smell, and taste of food, and by hormonal stimuli, chiefly the
hormone gastrin. As the food digests, it is churned by muscular action into a thick liquid state called chyme, at which point it passes into the small intestine.
