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 the coronary arteries and veins is to supply the heart with vital oxygen for it to function. It may also carry trace minerals that help it conduct and contract â¦ .o transport oxygenated blood though the system and into the veins to be oxygenated. The arteries' main functions are to carry blood (mainly erythrocytes, leukocytes, thrombocytes, and plasma) throughout the body. The blood carries oxygen, fights pathogens, clots blood, and maintains body temperature.
