The program teaches young viewers that, for food to be of use to our body's cells, food needs to be broken down and absorbed into the bloodstream. It is the job of the digestive system, a complex series of tools designed to reduce nutrients to a form that can be delivered to cells. Kids will also learn that waste products and indigestible materials must be removed from the body. It is the role of the excretory system, which includes the liver, lungs, kidneys and the skin.
