This edition: The Digestive and Renal Systems
The human body needs to take in food and water found in the environment, and through an almost miraculous sequence of mechanical and chemical processes, it converts that food into nutrients that sustain all the body's activities. The digestive tract alone has nine major organs devoted to this process and the renal tract three. Join world-renowned surgeon Dr. Mark Reisman as he provides you with a unique look at the anatomy and physiology of the many organs and structures of digestion. Lastly, discover the properties of metabolism and nutrition.
