Atrial natriuretic peptide - Wikipedia

WebNatriuretic hormones are peptides that stimulate the kidneys to excrete sodium—an effect opposite that of aldosterone. Natriuretic hormones act by inhibiting aldosterone release and therefore inhibiting Na + recovery in the collecting ducts. If Na + remains in the forming urine, its osmotic force will cause a concurrent loss of water. WebThe atrial natriuretic peptide (ANP) lowers blood pressure by acting as a vasodilator. It is released by cells in the atrium of the heart in response to high blood pressure and in patients with sleep apnea. ANP affects salt release, and because water passively follows salt to maintain osmotic balance, it also has a diuretic effect. WebNov 19, 2024 · HOW DO NATRIURETIC PEPTIDES WORK?
