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.

The correct answer for the above question is B, It prompts the kidneys to reabsorb more water into the blood stream to dilute the salts. When there is less water in the body, the pituitary gland releases more ADH to reabsorb more water in the bloodstream so the urine will be concentrated. On the other hand, when there is more water in the body, less ADH will be released to reabsorb less water in the blood, thus resulting to dilute urine. 

The answer is option a
