The stomach is a distensible sac connected to the esophagus proximally and the duodenum distally. It serves two major functions in the digestive system. First, it is a temporary holding area for food, slowly portioning the mass of consumed food into the duodenum for further digestion and absorption. Second, food is mixed with gastric secretions and churned to be broken down into a semiliquid form, termed chyme. Both the gross anatomy and the microscopic anatomy of the stomach reflect these functions.
