Last semester I took an anatomy class in which the main function of the colon was describes as absorbing water. It absorbs more water than the small intestine, its the last stage in making feces. They also say the colon absorbs the break down products of bacteria. The bacteria are mainly in the colon not the small intestine so if we get anything from the bacteria it would be from absorption by the colon. Frank.
