The vena cava allows blood to enter the right atrium. Unlike the rest of the heart, there are no valves separated the vena cava and right atrium. However blood backflow is not an issue because the pressure difference between the right atrium and the vena cava is not great, and when the heart pumps it partially compresses the vena cava.
