Functions of Digestive System

The functions of the digestive system is food is processed in your body in four stages; ingestion,digestion, absortion,and elmination. Digestion breaks down the food so that nutrients can be absorbed and move into the blood. The beging of the diegstion is in the mouth. When you are chewing your food, the slava starts to breaking it down smaller peaces to swallo so you don't choke. Then it goes through your esopagus, your muscels help pull it down so it does dont get stuck. When your food goes in your stomach acids come in and starts breaking down the food into smaller pieces.
