ADH and RAAS work together in maintaining osmoregulatory homeostasis through which of the following ways?
A)ADH regulates the osmolarity of the blood and RAAS regulates the volume of the blood.
B)ADH regulates the osmolarity of the blood by altering renal reabsorption of water, and RAAS maintains the osmolarity of the blood by stimulating Na⁺ reabsorption.
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)Both stimulate the adrenal gland to secrete aldosterone, which increases both blood volume and pressure via its receptors in the urinary bladder.
E)ADH and RAAS combine at the receptor sites of proximal tubule cells, where reabsorption of essential nutrients takes place.

ADH (antidiuretic hormone) helps maintain osmoregulatory homeostasis in the body by regulating water reabsorption in the kidneys. RAAS (renin-angiotensin-aldosterone system) helps maintain osmoregulatory homeostasis in the body by regulating salt and water balance. ADH and RAAS work together to regulate blood osmolarity and volume by altering renal reabsorption of water and stimulating Na+ reabsorption, respectively. Therefore, choice B is the correct answer.

ADH and RAAS Work Together in Maintaining Osmoregulatory Homeostasis Through
