Q. Which one of the following statements is correct with respect to kidney function regulation?
A) During summer when body loses lot of water by evaporation, the release of ADH is suppressed
B) When someone drinks lot of water, ADH release is suppressed
C) Exposure to cold temperature stimulates ADH release
D) An increase in glomerular blood flow stimulates formation of Angiotensin II
Explanation
[Solution from source] Drinking a lot of water dilutes the body fluids, so the hypothalamic osmoreceptors suppress ADH release and dilute urine is passed. Water loss in summer would stimulate ADH, and it is a fall in glomerular blood flow that triggers renin and angiotensin II formation. Answer (2).
