Summary: The digestive system is a group of organs that work together to break down food. The nutrients in most of the food you eat are large molecules, like lipids and proteins. During digestion, these large molecules are broken down into small nutrient molecules. These nutrients can then pass into the blood where they are used by the body. Figure 1 shows this process.
