The human gastrointestinal tract refers to the stomach and intestine , and sometimes to all the structures from the mouth to the anus . (The digestive system is a broader term that includes other structures, including the accessory organs of digestion ). In an adult male human , the gastrointestinal (GI) tract is 5m long in a live subject, or up to 9m without the effect of muscle tone , and consists of the upper and lower GI tracts. The tract may also be divided into foregut , midgut , and hindgut , reflecting the embryological origin of each segment of the tract. The GI tract always releases hormones to help regulate the digestion process. These hormones, including gastrin , secretin , cholecystokinin , and grehlin , are mediated through either intracrine or autocrine mechanisms, indicating that the cells releasing these hormones are conserved structures throughout evolution .
