What are the 6 veins that carry blood to the heart?
Aorta, Superior and Infurior Vena Cava, left and right pulmonary arteries/veins, coronary artery.
All veins do... But there are only 2 main ones..Superior and inferior vena cava. There is also coronary sinus that bring venous blood from the heart muscles back in the right atrium.
Actually all veins lead to the heart because they join at some point due to circulation. Some veins, however are superior to others but they all lead to the same vital organ... The heart.
