How do ADH and RAAS work together in maintaining osmoregulatory homeostasis?
A)ADH monitors osmolarity of the blood and RAAS regulates blood volume.
B)ADH monitors appropriate osmolarity by reabsorption of water, and RAAS maintains osmolarity by stimulating Na+ reabsorption.
C)ADH an RAAS work antagonistically; ADH stimulates water reabsorption during dehydration and RAAS removal of water when it is in excess in body fluids.
D)Both stimulate the adrenal gland to secrete aldosterone which increases both blood volume and pressure.
E)Only when they are together in the receptor sites of proximal tubule cells, will reabsorption of essential nutrients back into the blood take place.

ADH (antidiuretic hormone) regulates the concentration of urine by stimulating water reabsorption in the kidney tubules. RAAS (renin-angiotensin-aldosterone system) regulates blood pressure by stimulating the reabsorption of sodium and water in the kidney tubules. Together, ADH and RAAS work to maintain osmoregulatory homeostasis by monitoring osmolarity and maintaining appropriate levels of water reabsorption, which in turn regulates blood volume and pressure. ADH ensures that the urine does not become too concentrated, while RAAS ensures that the body does not lose too much water.
