What is the role of adh (antidiuretic hormone) in regulating salt and water concentrations in the blood?
a. it detects a high concentration of salts in the blood and signals the pituitary glands to release more water into the blood.

b. it prompts the kidneys to reabsorb more water into the bloodstream to dilute the salts.

c.
it inhibits the skin to sweat. this retains more water into the bloodstream to dilute the salts.

Right when there is not that a lot of water within the body, pituitary organ releases additional vasoconstrictor to resorb more water in the circulatory framework therefore the pee are targeted..but once there is additional water in body, less ADH can be discharged to resorb less water within the blood therefore it leads to a weaken pee.

So the answer you are looking for is B. It prompts the kidneys to reabsorb more water into the bloodstream to dilute the salts.

I hope this helps!
