When you eat, your body turns the food into energy and extracts vitamins, minerals and other nutrients to help it work properly. This process is called digestion. The parts of the body that are involved in digestion are called the digestive system.
The central part of the digestive system is a winding muscular tube called the GI (gastrointestinal) tract. It includes the:
- small intestine
- large intestine
Other parts of your body, called accessory organs, help the GI tract to digest food. These include the:
- gall bladder.
