Question

Quizplus · Accepted Answer

ANP (atrial natriuretic peptide) and BNP (brain natriuretic peptide) are both secreted by the heart in response to distension of the heart walls, specifically the atria and ventricles. This can occur due to increased blood volume or pressure, and the release of these peptides helps to regulate fluid balance, blood pressure, and other cardiovascular functions. The other options listed (low blood pressure, tachycardia, and low blood volume) may also have some impact on ANP and BNP secretion, but distension of the heart walls is the primary trigger.
