Large Intestine: Water Reabsorption
Captions available
The idea
The large intestine reabsorbs water from undigested material, hosts microbial flora that aid digestion, and compacts the remainder into feces stored in the rectum.
In practice
Too much water reabsorption produces constipation; too little produces diarrhea.
Where people slip
The large intestine does little chemical digestion of its own — it mainly reabsorbs water and hosts microbial flora, not breaks down macromolecules.
