Drinking alcoholic or caffeinated beverages increases urine output more than drinking an equivalent amount of water.
olga2289 [7]

Answer:

A) ADH secretion decreases. B) Urine osmolarity decreases.

Explanation:

Antidiuretic Hormone or ADH is responsible for the reabsorption of water through the kidneys.

A) Drinking alcoholic and/or caffeinated beverages decreases the release and effect of ADH so the water does not get absorbed as much as it should, which in turn results in more urination.

B) Osmolarity is a term used to express the concentration of a solution in terms of a certain particle. Since less ADH secretion results in more water being in the urine, this lowers the concentration of the urine. So urine osmolarity would be decreased.

I hope this answer helps.
