True
False
The stimulus that causes the release of ADH hormone into the blood to maintain water balance is
increased osmolality of the blood
increase dilution of solutes in the blood
increase diffusion of the blood

liver
lungs
What is regulation?
Maintains a low pH in the body.
Blood vessels help to maintain a high blood pressure by controlling the blood flow to the surface of the skin, also helps to balance the body's pH.
Blood vessels help to maintain a stable blood pressure by controlling the blood flow to the surface of the skin, also helps to balance the body's pH.
