Detailed explanation-1: -The role of the ascending colon is to absorb the remaining water and other key nutrients from the indigestible material, solidifying it to form stool. The descending colon stores feces that will eventually be emptied into the rectum.
Detailed explanation-2: -The colon helps to absorb a small volume of water from the lumen (400ml/day).
Detailed explanation-3: -The large intestine (colon) also absorbs some water. Nearly all the water is absorbed into the bloodstream from the small intestine. The excess fluid absorbed in the blood is filtered by the kidneys, which produce the urine that is transported to the bladder.
Detailed explanation-4: -By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished. The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.
