question 11

Multiple Choice

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+ and water 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, leading to an increase in both blood volume and pressure via receptors in the urinary bladder.
• E) They combine at the receptor sites of proximal tubule cells where reabsorption of essential nutrients takes place.
