Atrial Natriuretic Peptide (ANP) is a peptide hormone released primarily by the atria of the heart in response to stretching caused by increased blood volume and pressure. Its primary role is to counter the effects of the Renin-Angiotensin-Aldosterone System (RAAS) and lower blood pressure and volume. ANP acts on the kidneys to promote the excretion of sodium (natriuresis) and water (diuresis), thereby reducing blood volume. It also causes vasodilation (relaxation of blood vessels), which lowers peripheral resistance. Furthermore, ANP inhibits the secretion of renin, aldosterone, and vasopressin (ADH), all of which would otherwise raise blood pressure. This makes ANP a crucial hormone in the body's short-term and long-term regulation of blood pressure, fluid, and electrolyte balance.
