Your uptown line (upper body) veins, such as the veins in your higher back and chest, take deoxygenated blood onto your superior vena cava bus for return to your heart. Your coronary heart is the hub or destination the place all of the deoxygenated blood from the uptown and downtown bus traces (veins) goes.
