Stomach, bowel and digestion

The digestive system is made of a chain of muscles beginning with the mouth and ending with the back passage. The stomach receives food from the esophagus, mixes it, breaks it down and passes it on to the small intestine. From there most of the nutrients in the food enter the bloodstream. The rest is passed to the large intestine, which pushes it towards the anus, where the bowel is emptied.
