Coronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function, and oxygen-depleted blood must be carried away.The coronary arteries consist of two main arteries: the right and left coronary arteries.The left coronary artery system branches into the circumflex artery and the left anterior descending artery.oronary arteries supply blood to the heart muscle. Like all other tissues in the body, the heart muscle needs oxygen-rich blood to function, and oxygen-depleted blood must be carried away.
The right coronary artery and the left coronary artery branch off the aorta (just after it leaves the heart) to deliver oxygen-rich blood to the heart muscle. These two arteries branch into other arteries, including the circumflex artery, that also supply blood to the heart.The cardiac veins collect blood from the heart muscle and empty it into a large vein on the back surface of the heart called the coronary sinus, which returns the blood to the right atrium.lood Supply of the Heart. Like all organs, the heart needs a constant supply of oxygen-rich blood. A system of arteries and veins, called the coronary circulation, supplies the heart muscle (myocardium) with oxygen-rich blood and then returns oxygen-depleted blood to the right atrium.
