How do the human digestive system works?
The digestive system consists of the mouth, salivary glands, food pipe, stomach, small intestine, large intestine, pancreas and liver. The food first enters the mouth. Then saliva from the salivary gland changes starch into sugar. Them we chew it and send it down the food pipe. the stomach sends digestive juices which make the food into as soup. Then the food passes into the small intestine then into large intestine and then the waste material is removed from the body through the anus.
