When water is inadequate blood becomes concentrated, mouth becomes dry, hypothalamus initiates drinking behaviour. When water is excessive, stomach expands and stretch receptors send signals to stop drinking. Thrist, weakness, dry skin, rapid heartbeat, low bp. Lags behind body"s need; thirst comes after body already lost water.
