Absorption In The Large Intestine - Regulation - TeachMePhysiology

The large intestine (or colon) plays several key roles in maintaining fluid balance, supporting immunity, and processing waste.

It acts on material received from the small intestine – known as chyme – a semi-solid mixture of partially digested food and digestive secretions. By the time chyme enters the colon, most of its water content has already been absorbed, leaving a concentrated residue.

In this article, we will review the major functions of the large intestine and how these are achieved at a physiological level.
