- Water and some salts are absorbed from the undigested food in the large intestine. The undigested residues are expelled out of the body as faeces through the anus. The grazing animals like cows, buffaloes and deer are known as ruminants. They quickly ingest, swallow their leafy food and store it in the rumen.
