Question

Which of the following statements are CORRECT regarding angiotensin II? (A) It increases the glomerular filtration rate by causing vasoconstriction of the efferent arterioles (B) It enhances reabsorption of Na⁺ and water in the proximal convoluted tubule (C) It stimulates the adrenal cortex to release aldosterone (D) Angiotensin converting enzyme (ACE) converts angiotensin I to angiotensin II Choose the correct answer from the options given below:

Options

Choose one · Correct answer highlighted

(B), (C) and (D) only Correct (A), (D) and (E) only (D) and (E) only (A), (B) and (D) only
