Quizplus · Accepted Answer

Chemical digestion is the process by which enzymes break down large molecules into smaller molecules. This is necessary for nutrients to be absorbed and utilized by the body. Mechanical digestion refers to the physical breakdown of food, such as chewing and churning in the stomach. Absorption is the process by which nutrients are taken up by cells and transported into the bloodstream. Secretion refers to the release of substances by cells or glands, such as digestive enzymes or hormones.
