Question

Quizplus · Accepted Answer

Antidiuretic hormone (ADH) increases the permeability of the collecting ducts to water, allowing the kidneys to reabsorb more water and produce a more concentrated urine. ADH is released by the posterior pituitary gland in response to increased blood osmolarity or decreased blood volume.
