Question

Which of the following statements is incorrect with respect to ADH?

• A. It prevents excessive production of urine.
• B. It is also called vasopressin.
• C. It acts on the collecting duct.
• D. It decreases the glomerular filtration rate.

Answer 1

The correct option is D It decreases the glomerular filtration rate.

ADH (Anti Diuretic Hormone) is also known as vasopressin.
Diuresis means the loss of excessive water along with urine.
Thus, ADH prevents the excess loss of water.
It is secreted by the hypothalamus when the GFR reduces.
It prevents excess loss of water by acting on the later parts of the renal tubule and increasing the glomerular filtration rate.
