The digestive system is made up of the gastrointestinal tract - also called the GI tract. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Digestion is important because the body needs nutrients from food and drink to work properly and stay healthy. Each part of the digestive system helps to move food and liquid through the GI tract, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, the body can absorb and move the nutrients to where they are needed.
