Question

Quizplus · Accepted Answer

The first blood vessels to branch from the aorta as it leaves the heart are the right and left coronary arteries, which supply blood to the heart itself. Pulmonary arteries and veins are involved in the circulation between the heart and lungs, and they branch off from the right side of the heart. Coronary veins are responsible for draining blood from the heart muscle back into the circulation system but they do not branch out from the aorta.
