Digestive System.
The gastrointestinal tract (GI tract), digestive tract, guts or gut is the system of organs within multicellular organisms that takes in food, digests it to extract energy and nutrients, and expels the remaining matter. The major functions of the gastrointestinal tract are ingestion, digestion, absorption, and defecation. The GI tract differs substantially from animal to animal. The simplest form of gut consists of a single chamber with a single opening. However, most animals have guts forming a tube with an entrance at a mouth and an exit at an anus, often with several specialized sections between – some have additional complex structures such as multi-chambered stomachs or side-chambers. In an adult male human, the GI tract is approximately 6.5 meters (20 ft) long 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.
It is most
important to keep the digestive system well functioning since all sorts of
problems like colon stones could develop with a malfunctioning digestive system.
