Explanation:
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.
Detailed explanation-2: -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.
Detailed explanation-3: -Absorption of ingested water and most solutes occurs in the proximal small intestine, therefore the rate at which beverages are emptied from the stomach is an important factor in determining the rate of water absorption.
