colon(ko'lon) [L. colon, fr Gr. kolon, large intestine]
Mechanical: The colon mixes the intestinal contents. Chemical: The colon does not secrete digestive enzymes. The products of bacterial action that are absorbed into the bloodstream are carried by the portal circulation to the liver before they enter the general circulation. More water is absorbed in the colon than in the small intestine. In this way, body fluids are conserved, and despite the large volumes of secretions added to the food during its progress through the alimentary canal, the contents of the colon are gradually dehydrated until they assume the consistency of normal feces or even become quite hard. See: absorption, colon; defecation
Bacteria of the colon
The normal microbial flora in the colon, some of which may produce vitamins, esp. vitamin K; metabolize proteins and sugars; produce organic acids and ammonia; and deconjugate bile acids. Several conditions, such as use of antibiotics, corticosteroids, or dieting, may alter the normal flora. Although Escherichia coli is the most widely known bacterium that inhabits the colon, it is not the most common, being outnumbered by anaerobic Bacteroides species by a very wide margin.

Patient discussion about colon
Q. How is colon cancer diagnosed?
Q. how successful is the treatment of removing the colon? Are there any people who have had their colons removed successfullly? What other treatment options are there and how successful are they?
it's "success" as a treatment depends on the cause. i can tell you that this is the area that absorbs B12 and bile and most of the water, so expect a shortage of that three. in the water and bile case- expect watery stool...
sorry all that doesn't seem such a nice state but when Dr. come to the point they have to do it- there must be a good enough reason.
