Coronary circulation is the circulation of blood in the blood vessels of the heart muscle. 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. Most tissue perfusion in the heart occurs when the coronary arteries open during diastole.
The function of arteries is to take blood from the heart to parts of the body. There are two sets of arteries (relating to each side of the heart):- those that take blood f â¦ rom the heart to the lungs to be re-oxygenated; known as the pulmonary arteries.These are the only arteries that transport de-oxygenated blood.he function of the coronary artery is to carry oxygen and nutrients to the myocardium (heart muscle), it does not actually take the carbon dioxide away, (that is the job of t â¦ he great and small cardiac veins). 46 people found this useful.
