Oesophagus, Large Intestine, Rectum

In large intestine, undigested food enters where water is absorbed from it. No digestion takes place in the large intestine.
In rectum, semi-solid residue is stored and is finally thrown out of the body through the anus in the form of faeces. No digestion takes place in the rectum.
