The Digestive System
This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat. Digestion begins in the mouth, when you chew and swallow, and is completed in the small intestine.
Digestion involves mixing food with digestive juices, moving it through the digestive tract and breaking down large molecules of food into smaller molecules.
