The gastrointestinal tract, also called gastrointestinal tract, or food channel, is the organ system in multicellular animals that consume food, digested to extract energy and nutrients and expel waste remaining. The main functions of the gastrointestinal tract are ingestion, digestion, absorption and excretion.
The gastrointestinal tract differs substantially from one animal to another. For example, some animals have a stomach with several cameras, while some animals have stomachs that contain a single chamber. In a normal adult male, the gastrointestinal tract is approximately 6.5 m long and consists of the upper gastrointestinal tract and the lower intestinal tract. The intestinal tract can also be divided into pre intestine, bowel and intestine posterior half, reflecting the embryological origin of each segment of the intestinal tract..
