Question

Quizplus · Accepted Answer

Atrial natriuretic peptide (ANP) is a hormone secreted by the atria of the heart in response to increased blood volume and pressure. It acts to promote the excretion of sodium and water in the urine, which decreases blood volume and pressure. Therefore, the effect of ANP is to decrease blood pressure. It does not increase the secretion of aldosterone or antidiuretic hormone, and while it does decrease urine output, this is a consequence of its effect on sodium and water excretion.
