Gastrointestinal Tract – Diagram, Anatomy, & Disorders
The gastrointestinal (GI) tract is a long, twisting tube made up of hollow organs that starts at the mouth and ends at the anus. It comprises organs such as the mouth, esophagus, stomach, small intestine, and large intestine. Food taken in through the mouth undergoes the process of digestion in the stomach, absorption of nutrients and energy in the small intestine, and the waste stored in the large intestine is expelled at the anus as feces.
In this article, we will study in detail the definition of the gastrointestinal tract, its anatomy, digestive mechanism, functions of the GI tract, infection, and disorders that occur in the GI tract.
