Specifically, the superior and inferior vena cava carry deoxygenated blood back to the heart. The superior vena cava is bringing deoxygenated blood from the head and upper torso back to the heart's right atrium.
The right atrium is the upper chamber of the right side of the heart. The blood that is returned to the right atrium is deoxygenated (poor in oxygen) and passed into the right ventricle to be pumped through the pulmonary artery to the lungs for re-oxygenation and removal of carbon dioxide.he right atrium is the upper chamber of the right side of the heart.
