Quizplus · Accepted Answer

Vasopressin is produced in the hypothalamus and secreted by the posterior pituitary gland. It increases the permeability of the distal and collecting tubules to water, promoting water reabsorption. Its secretion is stimulated by a water deficit in the body, which triggers a feedback mechanism to increase water reabsorption and decrease urine output. Therefore, all of the given choices are correct.
