Vedclass · Answer

(B) An increase in blood flow to the atria of the heart causes the release of Atrial Natriuretic Factor $(ANF)$.$ANF$ causes vasodilation (dilation of blood vessels), which reduces blood pressure.This mechanism acts as a check on the Renin-Angiotensin mechanism, which is responsible for increasing blood pressure.Therefore, $A = ANF$, $B = 	ext{vasodilation}$, and $C = 	ext{renin-angiotensin mechanism}$.

An increase in blood flow to the atria of the heart can cause the release of $A$, which causes $B$ and thereby decreases the blood pressure. The $ANF$ mechanism therefore acts as a check on $C$. Here, $A-C$ refers to:
