The document describes the basic human digestive system process. Food is chewed in the mouth with teeth and mixed with saliva before passing through the esophagus into the stomach. In the stomach, gastric juices further break down the food into a thick liquid. This liquid then enters the small intestine where nutrients are absorbed with help from liver and pancreatic juices. Remaining waste moves to the large intestine and is eventually expelled through the anus as feces.
