Because water can absorb and transfer heat well, the human body uses it to stabilize temperature. Water has a relatively high heat capacity, meaning it can absorb a lot of heat before its temperature rises. ... Water also helps expel excess heat from the body as water vapor from the lungs and sweat on the skin.
When the blood plasma becomes less concentrated and the level of ADH decreases, aquaporins are removed from collecting tubule cell membranes, and the passage of water out of urine and into the blood decreases.
