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.
