Blood is carried by a (n) ___toward the heart

Answer

Blood is carried by a Superior and Inferior Vena Cava toward the heart

Explanation

Most veins transport deoxygenated blood through the tissues returning to the heart except pulmonary and umbilical vein that transfers oxygenated blood to the heart whereas arteries carry blood away from the blood. The main blood vessels aorta, superior vena cava, and inferior vena cava carry deoxygenated away from the heart to lungs while pulmonary veins carry the oxygenated that is oxygen-rich blood from lungs to the heart.
