*The colon is a site of microbial fermentation and absorption of the products of microbial fermentation, [[Volatile Fatty Acids - Anatomy & Physioogy|VFAs]].
*Transportation of chyme is also a function of the colon.
*Motility in most species is brought about by segmentation and peristalsis.

*Antiperistalsis also occurs and is particularly important in horses, ruminants and rodents.

**In the horse the antiperistaltic movements delay the movement of chyme from the ventral to the dorsal colon, which increases the time chyme is available for fermentation in the ventral colon.
