This digestive system mind map depicts the digestive system's process. Your digestive system is uniquely designed to convert your food into the nutrients and energy required to survive. After that, it neatly packages your solid waste, or stool, for disposal when you have a bowel movement. Digestion is vital because your body needs nutrients from the food and liquids you consume to stay healthy and function properly. As shown in this mind map, the main organs that comprise the digestive system (in order of operation) are the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus.
