Question

Complete the analogy.

ANP : inhibition of JGA cells : : Angiotensin II : ______

Options

• dilates arterioles in kidney

• enhances reabsorption of Na⁺ by PCT

• inhibition of aldosterone secretion

• stimulates diuresis

Answer 1

ANP : inhibition of JGA cells : : Angiotensin II : enhances reabsorption of Na⁺ by PCT

Explanation:

The analogy is based on how blood pressure and kidney activity are regulated.

Renin release is decreased when JGA (Juxtaglomerular Apparatus) activity is reduced by ANP (Atrial Natriuretic Peptide).

Angiotensin II (from the RAAS system) has the opposite effect:

• It enhances sodium (Na+) reabsorption, particularly in the proximal convoluted tubule (PCT).
• This helps in raising blood pressure and volume.
