This program examines the chemical structure of food and the human body's ability to convert food into fuel and raw materials. Major and minor nutrients are defined, catabolism and anabolism are contrasted, and the function of the digestive tract at the cellular level is scrutinized. The sequence of physical and chemical processes that facilitate digestion is also illustrated, spotlighting each constituent anatomical system: mouth/esophagus, stomach, small intestine, and large intestine. A segment on healthier eating concludes the program.
