Final answer:
The aorta is on the left side of the heart and the superior vena cava and inferior vena cava are on the right side.
Step-by-step explanation:
The aorta is the major artery of the body, taking oxygenated blood to the organs and muscles of the body. It is located on the left side of the heart. On the other hand, the superior vena cava drains blood from the head and from the veins that come from the arms, while the inferior vena cava drains blood from the veins that come from the lower organs and the legs. These major veins are located on the right side of the heart.
