A person who is unable to synthesize vasopressin

Question

Quizplus · Accepted Answer

Vasopressin, also known as antidiuretic hormone (ADH), is responsible for regulating water reabsorption in the kidneys. Without vasopressin, the kidneys cannot reabsorb as much water, resulting in increased urine output and a hypotonic urine (urine with a low concentration of solutes). Option A is incorrect because without vasopressin, the kidneys are unable to reabsorb water in the distal tubules and collecting ducts, not the proximal tubules. Option B is incorrect because glucose is normally reabsorbed in the proximal tubule, and vasopressin does not affect glucose reabsorption. Option D is also incorrect because the maximum urine output is around 20-30 L per day, even without vasopressin.
