Question

Volume of urine is regulated by:

• A. Aldosterone
• B. Aldosterone and testosterone
• C. ADH
• D. Aldosterone and ADH

Answer 1

The correct option is D

Aldosterone and ADH

In mammals and birds, the amount of water excreted in the urine, and thus the concentration of the urine, varies according to the changing needs of the body. Volume of urine is regulated by ADH and aldosterone. The osmotic gradient is normally constant, but the permeability of the collecting duct to water is adjusted by a hormone, antidiuretic hormone, ADH. Aldosterone maintains salt balance in the body.
