The Digestive System
 * 1) food first enters the mouth salivary glands under the tongue secrete digestive juices.
 * 2) food leaves the mouth and enters the pharynx, an opening between the mouth and nasal cavities.
 * 3) food is squeezed down by muscles through the esophagus a tube that runs from the pharynx to the stomach.
 * 4) food then enters an elastic muscular bag called the stomach.This bag churns and squeezes the food while mixing it with digestive juices.
 * 5) after food leaves the stomach it enters a 20-foot-long, thin tube called the small intestine where the food's nutrients are eventually absorbed into the bloodstream.
 * 6) food that has not been used in the small intestine moves on to a 5-foot-long, thick tube called the large intestine.this tube converts the food into feces.
 * 7) ﻿feces, food converted to semi-solid waste, leaves the large intestine and is held in a short tube called the rectum until it is expelled from the body.
