The Heart releases Natriuretic Peptides which act to lower blood pressure and thus work antagonistically to the Renin-Angiotensin-Aldosterone System.
Hormone | Secreted From | Action |
---|---|---|
Atrial Natriuretic Peptide | Atrial Myocytes | Released in response to triggers including atrial stretch, ANP increases sodium and thus water excretion at the kidneys, reducing blood volume and thus pressure. It also inhibits the Renin-Angiotensin Aldosterone System and relaxes arterioles. further reducing systemic blood pressure. |
B-Type Natriuretic Peptide | Ventricles of the Heart | Decreases vascular resistance, in the same ways as ANP but is 10x LESS potent. |
