The correct answer is: (B) Check on Renin-Angiotensin mechanism.
Atrial Natriuretic Factor (ANF) is a peptide hormone produced by the heart's atria. It plays a key role in regulating blood pressure and fluid balance within the body.
ANF primarily works to counteract the effects of the Renin-Angiotensin mechanism, which typically increases blood pressure through vasoconstriction and fluid retention. Specifically, ANF:
- Inhibits renin release: By reducing the release of renin, ANF decreases the production of angiotensin II, which is responsible for vasoconstriction and fluid retention.
- Promotes sodium excretion: ANF increases the excretion of sodium by the kidneys (natriuresis), which leads to a reduction in blood volume and helps lower blood pressure.
- Vasodilation: It also causes vasodilation, further contributing to the lowering of blood pressure.
Therefore, ANF acts as a check on the Renin-Angiotensin mechanism, helping to balance blood pressure and fluid levels in the body.
