There are three varieties of blood vessels: arteries, veins, and capillaries. During blood circulation, the arteries carry blood away from the heart. The capillaries connect the arteries to veins. Finally, the veins carry the blood back to the heart.
The superior and inferior venae cavae are the veins that return de-oxygenated blood from the body into the heart. They both empty into the right atrium.
The inferior vena cava (or posterior vena cava) travels up alongside the abdominal aorta with blood from the lower part of the body.
The superior vena cava (or anterior) is above the heart, and forms from a convergence of the left and right brachiocephalic veins that contain blood from the head and the arms. The vena cavae carry deoxygenated blood from the body to the right atrium of the heart.
The venae cavae is the largest blood vessel in the heart.

Veins carry blood back to the heart whereas arteries carry blood away (to the rest of the body, after being oxygenated). The aorta is a great vessel that is an artery (so it doesn't bring blood to the heart.... it takes it away). The pulmonary arteries carry blood from the heart to the lungs and the pulmonary veins carry blood from the lungs to the heart. This is the only time that arteries don't carry oxygenated blood (pulm. arteries). Otherwise that is another usual feature of arteries.
Major veins: superior and inferior vena cava- both innervate the right atrium of the heart, pulmonary veins- innervate the left atrium

It's the superior and inferior vena cavae. I guess you could kind of include the coronary sinus too if you want to be clever =P
These are the specific vessels that carry blood into the heart. The more general term for a vessel carrying blood towards the heart would be vein.
Edit: Yes pulmonary veins carry blood directly into the heart too. Can't believe I forgot those.

In simpler terms,venous blood vessels carries blood to the heart. That would include venules,veins and vena cavae (the superior and inferior vena cavae which are the largest veins carrying unoxygenated blood to the heart).The pulmonary veins carry oxygen-rich blood from the lungs to the left atrium of the heart.

Both, the superior and inferior venae cavae carry blood to the right atrium in the heart. The 4 pulmonary veins carry blood to the left atrium in the heart. It depends on which part of the heart you are refering to.

Pulmonary arteries carry blood away from the heart to the lungs Aorta carries blood away from the heart to the rest of the body

the vena cava (includes superior and inferior) carries deoxygenated blood from the body to the heart. the heart also receives freshly oxygenated blood from the pulmonary artery.

Veins, the last being vena cava. Go in peace.

The correct answer is the vena cava. The vena cava has several parts, so the previous answer about the "superior" vena cava is wrong. It's not just that part. Good luck!!
