What is the role of large intestine in human digestion process?

The material passing into the large intestine consists of water with undigested matter , largely cellulose and vegetable fibres ( roughage ) , mucus and dead cells from the lining of the alimentary canal .
- The large intestine secretes no enzymes but the bacteria in the colon digest part of the of the fibre to form fatty acids which the colon can absorb .
- Bile salts are also absorbed and returned to the liver by the blood circulation .
- The colon also absorbs much of the water from the undigested residues .
About 7 litres of digestive juices are poured into the alimentary canal each day . If the water from these was not absorbed by the ileum and colon , the body awould soon be dehydrated .
- The semi-solid waste , the faeces or 'stool' , is passed into the rectum by peristalsis and is expelled at intervals through the anus . The act of expelling the faeces is called Egestion or Defecation .
So simply , there is almost no digestion , mostly reabsorbtion of water and bile .

The large intestine is mechanical digestion; it absorbs water and is involved in peristalsis. It has nothing to do with enzymes, which is chemical digestion.
