This document discusses the human digestive and nutrient systems. It explains that the body transforms food into nutrients that cells use for energy. The respiratory system provides oxygen for this process while the circulatory system transports nutrients and waste. The digestive system breaks food down into nutrients and passes them to the bloodstream, while the excretory system eliminates waste substances. Digestion involves changes to food as it travels the digestive tract, with nutrients being absorbed into the blood and waste eliminated.
