Gastrointestinal system

The digestive or gastrointestinal tract (GIT) extends from the mouth to the anus and is responsible for receiving food, breaking it down into nutrients (digestion), absorbing these nutrients into the bloodstream and, finally, eliminating all the undigestable parts of the food from the body. The gastrointestinal tract consists of the following :

  • Mouth
  • Throat
  • Esophagus
  • Stomach
  • Duodenum
  • Small bowel
  • Colon
  • Rectum
  • Anus
The Digestive/Gastrointestinal system is also comprised of certain organs that lie outside the GIT, such as :
  • Liver (hepatobiliary system)
  • Spleen
  • Pancreas
