The function of the cecum is to help digest plants through the body.
The cecum stores food temporarily while helpful bacteria digest the cellulose found in the plant cells
In herbivores, the caecum plays an important role in digestion. For example, in horses, the caecum is the main site for the symbiotic bacteria which break down food (eg. cellulose) for the horse.

The caecum absorbs water and salts from undigested foods before they continue on to the large intestine.
The caecum of a squid has a digestive function. It absorbs fluid and salt after food has been digested inside of the squid.
