What:

"The human digestive system is like a flexible tube about 28 feet long that starts at the mouth and ends at the rectum. The major organs included in this critical body system are the mouth, pharynx, esophagus, stomach, small intestine, colon (large intestine) and rectum. All of the nourishment required by our body to sustain life and health pass through this sophisticated processing system"
