Read the following statements regarding the regulation of kidney function: (a) An increase in body fluid volume can switch on the osmoreceptors and stimulate ADH release. (b) Angiotensin II increases the glomerular blood pressure and thereby GFR. (c) Aldosterone causes reabsorption of Na ⁺ and water from the proximal convoluted tubule. (d) The ANF mechanism acts as a check on the renin-angiotensin mechanism. How many

Step-by-step solution

Statement (a) is incorrect because an increase in body fluid volume switches off the osmoreceptors and suppresses ADH release to complete the feedback loop. Statement (b) is correct as Angiotensin II is a powerful vasoconstrictor that increases glomerular blood pressure and GFR. Statement (c) is incorrect because Aldosterone causes the reabsorption of Na ⁺ and water from the distal parts of the tubule, not the proximal convoluted tubule. Statement (d) is correct because ANF causes vasodilation and decreases blood p
