B- Pressure difference between the vena cava and the atriumReason- Blood passes from the superior and inferior vena-cava into the right atrium- During this phase start of diastole- the pressure-drops in the right atrium- Thereby forcing the blood from vena cava to enter-the right atrium- During diastole as the atrium relaxes and enlarges in size-and then the pressure falls-
