Why does position affect your blood pressure and heart rate? Please compare sitting, standing and lying down?

Its ALL ABOUT GRAVITY. The heart has to pump blood EVERYWHERE. UP to the TOP of your head...all the way DOWN to your TOES...and then have it COME BACK UP to the heart. That is a LOT of WORK. Sitting down...less so. Lying down...even LESS. The less oxygen your body needs...the slower your heart rate.
