The digestive system. Organ systems are groups of organs that carry out a particular function. The human body has several organ systems, including: 1  The nervous system. 2  The respiratory system. 3  The reproductive system. 4  The digestive system.
Figure 26-1 shows the major organs of the digestive system. Table 26-1 summarizes the structures making up the digestive system. The main function of the overall digestive system (Box 26-1) is to break down food into simpler forms that the circulatory vessels can carry and pass through the cell membranes to the cells. The cells then use these food molecules or nutrients for energy and to build, maintain, and repair body tissues.
