Answer:
The correct answer will be- Atrial natriuretic factor (ANF).
Step-by-step explanation:
The atrium of the heart plays important role in regulating the blood volume and blood pressure. The mechanical stretching of the atria leads to the release of an important hormone called atrial natriuretic factor.
ANF acts by increasing the excretion of sodium and inhibition of renin in the kidney as well as antagonizing vasoconstriction and shifting the fluid from intravascular to the interstitial compartment in the cardiovascular system.
Thus, Atrial natriuretic factor is the correct answer.
