Which of the following best describes the coronary circuit?

The coronary circuit supplies the heart muscle: blood leaves the aorta through the coronary arteries, flows through vessels in the heart wall, and returns through the coronary veins. The veins drain toward the right side of the heart, after which blood can travel to the lungs. So “aorta, coronary arteries, heart walls, coronary veins, lungs” is the best match, even though the lungs are not directly connected to the coronary veins.
