the blood vessels that supply oxygen and nutrients to the tissues of the heart.

controls the movement of blood within the heart chambers, to the heart tissues.

Circulation of blood to the heart muscle associated with the blood carrying capacity of a specific vessel or development of collateral vessels (extra blood vessels).

is the circulatory system that supplies the heart with blood.

The coronary circulation consists of the blood vessels that supply blood to, and remove blood from, the heart muscle itself. Although blood fills the chambers of the heart, the muscle tissue of the heart, or myocardium, is so thick that it requires coronary blood vessels to deliver blood deep into the myocardium. The vessels that supply blood high in oxygen to the myocardium are known as coronary arteries.
