Which organs main function is water and mineral absorption?
The large intestine. The only organ in the body that absorbs most of the water you take in is the large intestine, and if you’re asking about ONE organ that does BOTH water and mineral absorption, then it’s most likely the large intestine. “Its function is to absorb the remaining water from indigestible food matter, as well as store the useless nutrients and wastes and flush them from the body.” http://en.wikipedia.org/wiki/Large_intes… Otherwise, the small intestines absorb the most minerals from the foods that you eat. The kidney does absorb water but for the main reason of disposing of excess water and also using it as a medium to excrete the body’s wastes. The kidney collects the wastes formed by the body’s metabolism, the main waste being urea. It is also responsible for balancing salt/water concentrations of the body.
