The document discusses the human digestive system. It begins with digestion occurring in the mouth through chewing and the use of saliva. Next, it describes the physical and chemical breakdown of food into simpler molecules through enzymes. It then explains absorption as the diffusion of simple substances into the blood and elimination as the removal of undigested waste. Diagrams of the anatomy of the digestive system and references are also included.
