The document summarizes the anatomy and physiology of the digestive tract. It describes each part of the digestive tract from the mouth to the anus. Key points include that the mouth begins digestion through chewing and saliva. Food then moves to the stomach through the esophagus. The stomach contains acid and enzymes that break down food into a liquid. This liquid moves to the small intestine where nutrients are absorbed into the bloodstream and lymph vessels. The large intestine absorbs water before waste is eliminated through the anus.
