ANATOMY

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: -Your small intestine moves water from your bloodstream into your GI tract to help break down food. Your small intestine also absorbs water with other nutrients.

Detailed explanation-3: -Water is absorbed by the large intestine by osmosis, with diffusion occurring in accordance with the osmotic gradient. Sodium is absorbed by the sodium/potassium pump in the colon, which diffuses potassium and sodium in opposite directions due to the formation of concentration gradients.
