The main and most important function of the small intestine is * absorption.

While digestion of food practically starts in the mouth (mechanical digestion, enzymatic digestion), and continues in the stomach (digestion of proteins), the small intestine finished the digestion (others then protein), and absorb everything the body needs. Leaving the large intestine to deal with the absorption of water, and as a place for some bacterial activity (certain vitamins). The small intestine also * transport

received the chime from the stomach, its peristaltic movement further it (what's left of it) down to the large intestine. It secrets * enzymes, digestive juices

necessary for the digestion/absorption/pH regulation. * It receives other necessary enzymes, chemicals from other organs (bile ect.) which it utilises in the above process.
