That would be true it one byte of data was stored using an electron, but in reality, I do believe it uses many.
Perhaps a little biology fact:
Blood from the lungs travel from through the pulmonary vein after being oxygenated. It then enters the heart through the left atrium, and then runs into the left ventrical before being pumped out the aorta at an incredible pressure, so much so, that if you were to rupture your aorta, then you would bleed out in seconds and also drown as your body cavity would fill with blood. :)
