Vasopressin does not increase the permeability of the proximal portion of the collecting tubule to urea. It primarily acts to increase the permeability of the distal and collecting tubules to water, thereby increasing water reabsorption and decreasing urine output. Its secretion is stimulated by a water deficit and it is secreted from the posterior pituitary gland.
