Which vein returns blood from the upper body to the right atrium?

Blood from the upper body returns to the heart through the superior vena cava. This large vein collects deoxygenated blood from the head, neck, and upper limbs (and upper chest) and channels it into the right atrium. The inferior vena cava handles the lower body, the coronary sinus collects venous blood from the heart muscle itself, and renal veins drain the kidneys into the systemic circulation via the inferior vena cava. So for returning blood from the upper body to the right atrium, the vessel is the superior vena cava.
