ADH and RAAS work together in maintaining osmoregulatory homeostasis through which of the following ways?
A) ADH regulates the osmolarity of the blood by altering renal reabsorption of water, and RAAS maintains the osmolarity of the blood by stimulating Na+ and water reabsorption.
B) both stimulate the adrenal gland to secrete aldosterone, which increases both blood volume and pressure via receptors in the urinary bladder.
C) ADH and RAAS work antagonistically; ADH stimulates water reabsorption during dehydration and RAAS causes increased excretion of water when it is in excess in body fluids.
D) ADH regulates the osmolarity of the blood and RAAS regulates the volume of the blood.
E) by combining at the receptor sites of proximal tubule cells, where reabsorption of essential nutrients takes place.
