Answer #1

False. ADH level determine the osmolarity and blood pressure by vasoconstructor effect. ADH is released in large quantities immediately after the hemorrage or hypotension. It is probably due to increased osmolarity of body fluid by aldosterone induced sodium retension. And it promote water retension.

ADH plays a role in lowering osmolarity or reducing sodium concentration by increasing water reabsorption in the kidneys, thus helping to dilute the fluids in the body. To prevent osmolarity become below normal, the kidneys also have a regulated mechanism for reabsorbing sodium in the distal nephron. The ADH hormone mainly act in the distal convoluted tubule (DCT) and collecting ducts.
