Let's review. Your veins drain deoxygenated blood from your body tissues and return it to the heart. Small veins converge to form larger and larger veins, which eventually drain into the venae cavae. The venae cavae empties the deoxygenated blood into the right atrium of the heart. The venae cavae has two divisions.The superior vena cava resembles a drain that leads down into the heart.mall veins converge to form larger and larger veins, which eventually drain into the venae cavae.
