An increase in blood flow to the atria of heart can cause release of ...A... causes ...B... and thereby decreases the blood pressure. ANF mechanism therefore acts as a check on ...C... .

(A)A-ANF, B-vaso constrictor, C-renin-angiotensin mechanism
(B)A-ANF, B-vasodilator, C-renin-angiotensin mechanismCorrect
(C)A-vasopressin, B-vasodilator, C-renin-angiotensin mechanism
(D)A-vasopressin, B-vaso constrictor, C-renin-angiotensin mechanism

Answer: (B)

Solution

Increased atrial blood flow triggers the release of ANF, which causes vasodilation (not vasoconstriction) and thereby lowers blood pressure, acting as a
