none.
Explanation:
The deoxygenated blood enters both vena cava's(superior and inferior) then into the right atrium, the right ventricle then up into the pulmonary artery which takes the blood to the lungs to be oxygenated. The oxygenated blood returns via the pulmonary veins, empties into the left atrium then the left ventricle and up into the aorta to be used by the body.
