Answer:
The combined effect of water retention (thanks to ADH) and increased water consumption leads to an increase in blood volume and subsequent restoration of fluid balance in the body. By increasing blood volume, ADH also plays a role in reducing plasma osmolality and therefore sodium concentration.
Step-by-step explanation:
Anti-diuretic hormone(ADH) helps to control blood pressure by acting on the kidneys and the blood vessels.
Its most important role is to conserve the fluid volume of your body by reducing the amount of water passed out in the urine.
