Approximately what percentage of water absorption takes place in the small intestine vs. the colon (and a followup question)?

1 Answer

Answer :

The gi tract requires chyme to be pretty liquid in order to be able to move it around through peristalsis. So even though the small bowel does absorb a lot of water from the chyme it is not until the colon that it starts to become solid. In fact the rectum and left colon are much more muscular than the right colon just to deal with the more solid stool.
