Vedclass · Answer

(A) The Atrial Natriuretic Factor $(ANF)$ is a peptide hormone released by the atrial walls of the heart in response to an increase in blood flow or blood pressure.$ANF$ acts as a vasodilator and promotes the excretion of sodium and water,thereby reducing blood volume and pressure.It functions as a check on the Renin-Angiotensin-Aldosterone System $(RAAS)$ by inhibiting the release of renin from the Juxtaglomerular $(JG)$ apparatus.Therefore,both the Assertion and the Reason are correct,and the Reason is the correct explanation of the Assertion.

$A :$ Atrial Natriuretic Factor $(ANF)$ is released by the wall of the atria.
$R :$ It inhibits the release of renin from the Juxtaglomerular $(JG)$ apparatus.
