Digestive System
The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract).

Study Tips
When studying the digestive system, it is important to understand the functions of each organ and the process of digestion. Use diagrams and flow charts to visualize the pathway of food through the digestive system. Practice labeling the organs and their functions to reinforce your understanding.
