This live-action program teaches students that, for food to be of use to our body’s cells, it needs to be broken down and absorbed into the blood stream. This is the job of the digestive system, a complex series of tools that includes teeth, saliva, bile, acids and enzymes designed to reduce nutrients to a form that can be delivered to cells. Students will come to understand that waste products and indigestible materials must be removed from the body. Viewers will learn that this is the role of the excretory system, which includes the liver, lungs, kidneys and the skin. Animation, graphics and live action video are used to demonstrate how the digestive system gets nutrients and energy from the foods you eat and how the excretory system removes excess or unnecessary materials from your body to keep it healthy.
