  1. A decrease in blood pressure/ volume will not cause the release of:
    1. Atrial natriuretic factor
    2. Aldosterone
    3. ADH
    4. Renin
Correct Option: A

A decrease in blood pressure/ volume stimulates the release of renin, aldosterone, and ADH while increase in blood pressure
/ volume stimulates the release of Atrial Natriuretic Factor (ANF) secreted by atria of heart, which causes vasodilation and also inhibits RAAS (Renin Angiotensin Aldosterone System) mechanism that decreases the blood volume/pressure.
