Question

Quizplus · Accepted Answer

Aldosterone directly stimulates Na⁺ reabsorption by the distal and collecting tubules.

Answer: D 
 Angiotensin II also indirectly stimulates Na⁺ reabsorption by promoting the secretion of aldosterone.

Answer: F 
 Atrial natriuretic peptide is a hormone released by the atria of the heart that opposes aldosterone and promotes sodium excretion. It does not stimulate Na⁺ reabsorption.

The remaining choices (A, B, and C) are involved in the renin-angiotensin-aldosterone system but do not directly stimulate Na⁺ reabsorption.
