The Digestive System
The digestive system is a system of organs that take in food, digest it to extract energy and nutrients, and expel the remaining waste. It incorporates the excretory and urinary systems, responsible for discharging waste from the body. The Digestive System Web Guide provides the “ins and outs” of the digestive, urinary and excretory systems.
