WebANP stimulates vasodilation of the afferent arteriole of glomerulus: this results in increased renal blood flow and an increase in glomerular filtration rate. Increased glomerular filtration, coupled with inhibition of reabsorption, results in increases in excretion of water and urine volume - diuresis! WebHow does ANP help to counter the RAAS? Answers: By stopping the secretion of renin and aldosterone, increasing sodium reabsorption, and decreasing the glomerular filtration rate.

WebAtrial Natriuretic Peptide (ANP) is a peptide hormone released by cardiomyocytes primarily in the right and left atria of the heart. Release of ANP is stimulated by over-stretching of the atria and thus occurs in contexts of cardiac over-filling.
