The correct answer is: An increase in blood flow to the atria of the heart can cause the release of atrial natriuretic factor (ANF) to decrease blood pressure.
The functioning of kidneys is effectively monitored and regulated by hypothalamus, juxta-glomerular apparatus, and to a certain extent, the heart.

An excessive loss of fluid from the body can activate the osmoreceptors of hypothalamus to release vasopressin or ADH from neurohypophysis. Angiotensin II is a powerful vasoconstrictor, which increases the glomerular blood pressure as well as GFR.
