The gastrointestinal tract is a tube like structure which extends from the mouth to the anus and supplies the various body systems, including itself, with nutrients, electrolytes and water through performing five functions. These functions include digestion, secretion, absorption, storage and excretion. To orchestrate these functions there are two control systems located inside and outside the gut wall. The intrinsic ones include the enteric nervous system and five hormones including secretion, gastrin, cholecystokinin, gastric inhibitory peptide and motilin and the extrinsic control system of the gut include the vagus and splanchnic nerves and the hormone aldosterone. This review describes the previous systems and their roles in the control of the various functions of the gut.
