Question

Quizplus · Accepted Answer

ADH (Antidiuretic Hormone), also known as vasopressin, is released by the posterior pituitary gland, not the adrenal gland, in response to high solute concentrations in the blood or low blood volume. Its primary function is to increase water reabsorption in the kidneys, thereby reducing urine volume and increasing blood volume. On hot days when you sweat, your body loses water, and ADH is released in greater quantities to conserve water by increasing the permeability of the collecting ducts to water, leading to more water being reabsorbed back into the bloodstream.
