LEARNING OBJECTIVES
1. The body is a system of interacting subsystems composed of groups of cells.
2. Digestion is the process of breaking down food in the alimentary canal into substances that can be used by the body.
3. Food is rearranged through chemical reactions forming new molecules that support growth and/or release energy as this matter moves through an organism.
4. Malnutrition is the result of inadequate and/or unbalanced intake of nutrients, with the latter beginning to overtake the former in terms of global health impacts

Chemical digestion
Digestion is the process of breaking down food in the alimentary canal into substances that can be used by the body.
Thousands of enzymes are found in living cells where they act as catalysts for the thousands of chemical reactions which occur. In addition to making life possible, many enzymes have numerous applications that affect our daily lives in other ways such as food processing, clinical diagnoses, sewage treatment, and the textile industry. (Miller, S. B)
