Which structures bring oxygen-rich blood to the heart?

Explanation:
Oxygen-rich blood reaches the heart through two routes. The coronary arteries supply the heart muscle itself with oxygenated blood, keeping the myocardium nourished. The lungs’ oxygenated blood returns to the heart via the pulmonary veins, delivering it into the left atrium. In contrast, the superior and inferior vena cavae bring deoxygenated blood into the right atrium, and the aorta carries oxygenated blood away from the heart to the body. So the structures bringing oxygen-rich blood to the heart are the coronary arteries and the pulmonary veins.
