Atrial Natriuretic Peptide (ANP) is a hormone secreted by the atrial myocytes (muscle cells) of the heart in response to excessive stretching of the atrial walls, which occurs when blood volume and pressure are high. ANP acts to lower blood pressure and volume by promoting vasodilation and increasing the excretion of sodium (natriuresis) and water by the kidneys. It also inhibits the renin-angiotensin-aldosterone system (RAAS) and the release of ADH.
