BCS0026 - Anatomy and Physiology: The Digestive SystemEvery time we eat, our food begins a remarkable journey through a long tube called the alimentary canal. Along the way chemicals and fluids are added to break down and process the food into substances called nutrients. These nutrients pass into the bloodstream, where they are delivered to every cell in our body to provide the energy we need to move and grow. The process of changing food into usable substances is accomplished by various organs that work together to form the digestive system. |
