I think the water is absorbed by the intestinal walls in the ascending and transverse colon, and to some extent by the descending colon. It should be to its final consistency when it reaches the rectum. The rectum just serves as a storage chamber to hold it so we can have one bm instead of 10 little ones. Unless we have proctitis, of course, in which case the irritated rectum won't hold anything, so we go all day.
