Atrial natriuretic peptide (ANP) is the hormone that promotes a decrease in blood pressure and a loss of sodium and water in urine. It is released by the atria of the heart in response to increased blood volume and pressure. ANP works by dilating blood vessels, promoting sodium and water excretion by the kidneys, and reducing renin and aldosterone release.
