==Function==

The colon is a site of microbial fermentation and absorption of the products of microbial fermentation, [[Volatile Fatty Acids|volatile fatty acids(VFAs)]]. Transportation is also important here. Motility in most species is brought about by segmentation and [http://en.wikipedia.org/wiki/Peristalsis| peristalsis]. '''Antiperistalsis''' also occurs and is particularly important in horses, ruminants and rodents. Chyme is transported towards the small intestine so as to fill the [[Caecum - Anatomy & Physiology|caecum]]. 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. ''Mass movements'' move the content of the large intestine into the [[Rectum - Anatomy & Physiology|rectum]].
