What is the Function of the Colon?

As the final link in the digestive chain, it is the colon’s job to 1) absorb any remaining water and electrolytes from the chyme, 2) to continue moving the waste material along its way, and 3) to store the waste material until it is time for it to be evacuated.

The colon moves material through by involuntary wavelike contractions, made possible by smooth muscles within the colon wall, a process which is referred to as peristalsis.
