Read the following statements regarding the regulation of kidney function: (A) Angiotensin II is a powerful vasoconstrictor that increases the glomerular blood pressure. (B) Aldosterone causes reabsorption of Na ^+ and water from the proximal convoluted tubule. (C) An increase in body fluid volume stimulates the osmoreceptors to release antidiuretic hormone (ADH). (D) The Atrial Natriuretic Factor (ANF) mechanism act

Step-by-step solution

Let us evaluate each statement based on NCERT: Statement (A) is correct. Angiotensin II is a powerful vasoconstrictor that increases glomerular blood pressure and thereby GFR. Statement (B) is incorrect. Aldosterone causes reabsorption of Na ^+ and water from the distal parts of the tubule, not the proximal convoluted tubule (PCT). Statement (C) is incorrect. An increase in body fluid volume switches off the osmoreceptors and suppresses the ADH release to complete the feedback, whereas a decrease in fluid volume st
