BIO302: Human Anatomy

Unit 9: Digestive System   Digestion allows you to extract useful nutrients from your food.  The digestive process begins as soon as you put food into your mouth, when your teeth and saliva begin to break down food items into more manageable sizes, and continues into the stomach and intestines.  In this unit we will familiarize ourselves with the names and functions of each organ in the digestive system.  We will also learn about the structures of the unique tissues and glands that enable us to absorb nutrients from food.
