Question

Which of the following statements is correct with respect to kidney function?

• A. During summer when body loses a lot of water by evaporation, the release of ADH is suppressed
• B. Exposure to cold temperature stimulates ADH release
• C. An increase in glomerular blood flow stimulates formation of angiotensin II
• D. When someone drinks a lot of water, ADH release is suppressed

Answer 1

The correct option is D

When someone drinks a lot of water, ADH release is suppressed

Antidiuretic hormone (ADH) or vasopressin increases the reabsorption of water in the distal convoluted tubule, collecting tubules and collecting ducts of the nephrons in the kidneys. As a result, the reabsorption of water from the glomerular filtrate is increased. When someone drinks a lot of water, requirement of absorption of water decreases, so ADH release is suppressed.
