Final answer:
Atrial natriuretic peptide (ANP) is the beta natriuretic peptide that rules out CHF by lowering blood volume, pressure, and sodium concentration in the body.
Step-by-step explanation:
The beta natriuretic peptide that rules out CHF is called atrial natriuretic peptide (ANP). ANP is released by cells in the atria of the heart in response to high blood pressure and heart failure. It works to lower blood volume, pressure, and sodium concentration by promoting loss of sodium and water from the kidneys, suppressing hormone production and release that promote fluid retention, and vasodilating the blood vessels.
