Introduction:  The process of altering composition of food for the purpose of its absorption into the body is known as digestion.  Digestion depends on both the endocrine and exocrine secretion and the controlled movement of food through the tract for the purpose of absorption.  The purpose of the digestive system is to bring essential nutrients into the internal environment so that they are available to each cell of the body.  These functions include ingestion, digestion, motility, absorption, and eleimation.
