With one exception, veins carry oxygen-poor blood back to the heart. The largest and last blood vessel they pass through is called the superior vena cava.
The exception is the Pulmonary Vein, which carries oxygen-rich blood from the lungs to the heart to be pumped to the rest of the body.
The coronary arteries are the blood vessels that bring oxygenated blood to the muscle of the heart.
The Vein does not bring blood to the Heart.

pulmonary artery
The pulmonary vein carries blood from the lungs to the left atrium of the heart. The coronary arteries supply blood to the heart muscles. The Inferior and Superior Vena Cava bring the used blood from the body to the heart.
Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.
Not all arteries carry oxygenated blood. The definition of an artery is a vessel that carries blood away from the heart. There are the pulmonary arteries that carry blood low in oxygen from the heart to the lungs. Pulmonary veins bring blood higher in oxygen back to the heart. Then that blood is sent out the rest of the body.
Pulmonary vein
coronary blood vessels.......
Arteries carry oxygen-poor blood from the heart; veins carry oxygen-poor blood back to the heart.
The inferior and superior vena cavas bring blood from the body to the right side of the heart. The pulmonary veins bring blopd from the lungs to the left side of the heart.
The pulmonary veins carry O2 rich blood to the heart.
