THE DIGESTIVE SYSTEM
The job of your digestive system is to break down the food that you eat into small molecules. These molecules give you energy,make you grow and make your body work well.
It starts in the Mouth,
the food goes down through the Esophagus,
to the stomach and then to
the small and large intestine where the food and water is absorbed; finally
it ends at the rectum or at the anus where the food waste goes out of the body.
