The digestive system breaks down food and fluids into much smaller nutrients. In this complex process, blood carries the nutrients throughout the body to nourish cells and provide energy. The GI tract is divided into two main sections: the upper GI tract and the lower GI tract.
* Upper GI tract — mouth, pharynx, esophagus and stomach. The stomach leads to the small intestine. * Lower GI tract — intestines (bowel) and the anus. The bowel is made up of two sections:
* Small intestine — the duodenum, jejunum and ileum * Large intestine — the cecum (where the appendix is attached), colon and rectumIn addition, the liver, pancreas and gallbladder produce digestive juices to aid the digestion of food.
