Solution

ANF is released when blood pressure rises.

A decrease in blood pressure/volume stimulates the release of renin, aldosterone and ADH, while an increase in blood pressure/volume stimulates the release of atrial natriuretic factor (ANF). ANF causes vasodilation and inhibits the RAAS (renin–angiotensin–aldosterone system), decreasing blood volume/pressure.
