What Does ANF Stand For?

ANF stands for Atrial Natriuretic Factor

Atrial Natriuretic Factor (ANF) is a peptide hormone produced by the cardiac atria in response to increased blood volume and pressure. It plays a crucial role in cardiovascular homeostasis by promoting natriuresis, the excretion of sodium through urine, and reducing blood pressure. ANF acts primarily by inhibiting renin release, decreasing aldosterone secretion, and promoting vasodilation, thereby contributing to fluid balance and blood pressure regulation.
