Question

Quizplus · Accepted Answer

Natriuretic peptides, such as atrial natriuretic peptide (ANP), are released by cardiac muscle cells in response to increased atrial distension. ANP promotes diuresis and natriuresis, lowering blood volume and pressure. This hormone opposes the actions of aldosterone and ADH. Choice A (ADH) and B (aldosterone) are incorrect because these hormones promote water and sodium reabsorption, increasing blood volume and pressure. Choice C (PTH) and D (acetylcholine) are not involved in the regulation of cardiovascular physiology.
