Intro to the Digestive System


The digestive system, also known as the Gastrointestinal tract or the Alimentary tract, is a long tube that is located between the mouth and the rectum. The digestive system provides the body with fuel and performs many other chemical exchanges. It consists of a muscular tube, the digestive tract and various accessory organs. The food you eat goes through the digestive tract.

The digestive system is made up of several organs. Each organ is responsible for a specific task when digesting food. The organs that make up the digestive system are: the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. There are also other organs called the accessory organs. The accessory organs consist of the liver, gall bladder, and pancreas.

The digestive system mixes, mashes, and breaks down foods into nutrients that the body can use. The digestion process begins as you take your first bite of food and ends as your body disposes of unnecessary products called bile. The primary organs do most of the work when digesting food and the accessory organs process the nutrients, store the bile, and secrete and absorb digestive enzymes.
