Digestive System
1011302 Digestive SystemObjective A To define digestion as a mechanical and chemical process. The food we eat is used at the cellular level in chemical reactions involving synthesis of proteins, carbohydrates, hormones, and enzymes; cellular division, growth, and repair; and production of heat. To become usable by the cells, most food must first be mechanically and chemically reduced to forms that can be absorbed through the intestinal wall and transported to the cells by the blood.
