DVD Description
Our Digestion DVD first examines the mechanical and chemical breakdown of food that occurs in the mouth and stomach before looking at digestion and absorption in the small intestine and the enzymes and other chemicals secreted by the liver, gall bladder, and pancreas that aid in the process. The program then looks at the synthesis of vitamins by bacteria in the large intestine and then goes on to explore the complex structures in the kidney that allow them to filter wastes out of the blood while returning water and nutrients.
