What blood vessels bring blood back to the right side of the heart from the upper body?

The blood vessels that bring blood back to the right side of the heart from the upper body are the superior vena cava and the inferior vena cava. The superior vena cava collects deoxygenated blood from the head, neck, arms, and upper torso, while the inferior vena cava returns blood from the lower body. Both vessels empty their contents into the right atrium of the heart.
