Read the following statements carefully: (A) A fall in GFR can activate the JG cells to release renin. (B) Angiotensin II is a powerful vasodilator that increases the glomerular blood pressure. (C) An increase in body fluid volume switches on the osmoreceptors and stimulates ADH release. (D) Aldosterone causes reabsorption of Na ⁺ and water from the proximal convoluted tubule. How many of the above statements are cor

Step-by-step solution

Statement (A) is correct. A fall in glomerular blood flow/glomerular blood pressure/GFR can activate the JG cells to release renin. Statement (B) is incorrect. Angiotensin II is a powerful vasoconstrictor, not a vasodilator. Statement (C) is incorrect. An increase in body fluid volume switches off the osmoreceptors and suppresses the ADH release to complete the feedback. Statement (D) is incorrect. Aldosterone causes reabsorption of Na ⁺ and water from the conditional/distal parts of the tubule, not the proximal co
