Natriuresis is the process of excretion of sodium in the urine.

Atrial Natriuretic Peptide (ANP) is a hormone secreted by the atrial walls of the heart in response to an increase in blood volume and pressure. ANP acts on the kidneys to increase sodium excretion (natriuresis) and water excretion, which helps to lower blood pressure and blood volume.

Aldosterone and renin promote sodium reabsorption, thereby decreasing natriuresis, while ADH primarily promotes water reabsorption.

Answer: ANP
