Function of the Digestive System. The primary function of the digestive system is to break down the food we eat into smaller parts so the body can use them to build and nourish cells and provide energy. The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
Your digestive system breaks nutrients into parts that are small enough for your body to absorb. How does my digestive system work? Each part of your digestive system helps to move food and liquid through your GI tract, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed.
