Question

which blood vessels supply blood only to heart

Answer 1

The aorta divides into two main blood vessels called arteries.The arteries branch off into smaller arteries, which supply oxygen-rich blood to the entire heart muscle. The right artery supplies blood mainly to the right side of the heart.

Answer 2

Coronary circulation is the circulation of blood in the blood vessels of the heart muscle (myocardium). The vessels that deliver oxygen-rich blood to the myocardium are known as coronary arteries. The vessels that remove the deoxygenated blood from the heart muscle are known as cardiac veins.
