How Do ADH and RAAS Work Together in Maintaining Osmoregulatory

question 29

Multiple Choice

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.
