Anatomy of GI system

The gastrointestinal tract (digestive tract, digestional tract, GI tract, GIT, gut, or alimentary canal) is an organ system within other animals and humans which takes in food, ,extract and absorb energy and nutrients and expels or excretes the remaining waste as feces. The part of the gastrointestinal tract is the mouth, esophagus, stomach and intestines. A tract is a collection anatomic structures or a series of connected body organs. The tract is divided into upper and lower tracts, and the intestines small and large parts. The gastro-intestinal system is a long tube running right through the body, with specialized sections capable of digesting material and extracting any useful components from it, then excreting the waste products at the bottom end. Nutrients from the GI tract are taken to the liver to be broken down further, stored, or distributed.
