GENERAL HISTOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Most water absorption takes place in the distal third of the small intestine, but the bulk of intestinal water is absorbed by the large intestine. However, Na+ and water absorption in the small intestine is important in absorption of nutrients and other ions.

Detailed explanation-3: -Small intestine. The walls of the small intestine absorb water and the digested nutrients into your bloodstream.

Detailed explanation-4: -Most of the water in ingested food and beverages is absorbed by osmosis. Approximately 80% is absorbed by the small intestine, 10% by the large intestine and the remaining 10% excreted in the faeces.
