It is connected to the small intestine, the anus, and the appendix.
It has several parts: Cecum (Small intestine and Appendix connect here), Ascending (Right side), Transverse, Descending (Left side), Sigmoid, and Rectum (connects to anus).
There is a right colic flexure (hepatic) and a left colic flexure (splenic).
It is different from the small intestine in that: it does not have absorptive villi, it is larger in diameter, the outer longitudinal muscle is bundled into three taenia coli, the walls are organized into sack-like structures called haustra, it functions mostly to absorb water and to store/pass feces to the anus, and has lots of mucous producing goblet cells. Any digestion of residual foodstuff that happens here is generally done by bacteria. There is a significant amount of immunologic tissue/cells in the walls of the colon that keep the peace with these bacteria.
