stomach definition

An organ in the digestive system, on the left side of the body behind the lower rib cage, that receives chewed food from the esophagus. Tiny glands in the stomach’s lining secrete gastric juice, which contains acids, mucus, and enzymes. This fluid, along with the muscular churning actions of the stomach, helps transform food into a thick, semifluid mass that can be passed into the small intestine for digestion.
