The gastrointestinal tract or digestive tract, also referred to as the GI tract or the alimentary canal or the gut, is the system of organs within multicellular animals which takes in food, digests it to extract energy and nutrients, and expels the remaining waste.
The GI tract differs substantially from animal to animal.
For instance, some animals have multi-chambered stomachs.
