“ANP increases glomerular filtration rate and glomerular permeability. ANP directly dilates the afferent arteriole and counteracts the norepinephrine induced vasoconstriction of the afferent arteriole. Some studies suggest that ANP also constricts the efferent arteriole, but this is not a unanimous finding. ANP inhibits the effect of Angiotensin II on the mesangial cells, thereby relaxing them. ANP increases the radius and number of glomerular pores, thereby increasing glomerular permeability."

“The medullary collecting duct is the main site of ANP regulation of sodium excretion. ANP effects sodium channels at both the apical and basolateral sides. ANP inhibits ENaC on the apical side and the Sodium Potassium ATPase pump on the basolateral side in a cGMP PKG dependent manner resulting in less sodium re-absorption and more sodium excretion."
