Question

Quizplus · Accepted Answer

Antidiuretic hormone (ADH), also known as vasopressin, primarily functions to increase the permeability of the collecting ducts in the kidneys to water. This action allows more water to be reabsorbed back into the bloodstream, reducing urine volume and concentrating the urine. This mechanism is crucial for the body's water balance and regulation of blood pressure.
