Coronary Arteries and Heart Function - Topic Overview Circumflex artery, which passes behind the heart between the left atrium and left ventricle and supplies blood to the side (lateral wall) of the left ventricle. In a small number of people, the circumflex artery supplies the lower and back portions of the left ventricle. The right coronary artery supplies blood to the right ventricle and then supplies the underside (inferior wall) and backside (posterior wall) of the left ventricle. What are collateral coronary arteries?

- Main navigation | Main content. Go to the U of M home page. Location: The circumflex artery branches off of the left coronary artery and supplies most of the left atrium: the posterior and lateral free walls of the left ventricle, and part of the anterior papillary muscle.ore likely, the circumflex artery may continue through the AV sulcus to supply the posterior wall of the left ventricle and (with the right coronary artery) the posterior papillary muscle of the bicuspid valve. The left circumflex branches decrease in diameter along their lengths.

Blood supply of the Heart Anatomy. The first branches that radiate from the ascending aorta, as it emerges from the left ventricle, are the left and right coronary arteries, which directly provide an arterial blood supply to the cardiac muscle. They arise from the bilateral aortic sinuses which are situated just distal to the aortic valve.

The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary divides into branches:The left anterior descending artery, which branches off the left coronary artery and supplies blood to the front of the left side of the heart.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 coronary arteries run along the outside of the heart and have small branches that dive into the heart muscle to bring it blood.

Anatomy and Function of the Coronary Arteries Right coronary artery (RCA). The right coronary artery supplies blood to the right ventricle, the right atrium, and the SA (sinoatrial) and AV (atrioventricular) nodes, which regulate the heart rhythm. The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery.

- The Coronary Arteries are the blood vessels that supply blood to your heart. They branch off of the aorta at its base. The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.

What does the right coronary artery do? A , Cardiology (Cardiovascular Disease), answered. The coronary arteries supply blood to the heart muscle itself. The right coronary artery is the major artery that supplies blood to the upper and lower chambers on the right side of the heart. There is also a left coronary artery. Watch this animation to learn more about these arteries.

Coronary Arteries and Heart Function - Topic Overview Your left ventricle pumps blood into the main artery of your body, called the aorta. See a picture of the heart and coronary arteries. Close to the heart, the two main coronary arteries branch off of your aorta. The left main coronary artery is a short vessel that branches into the: Left anterior descending artery, which supplies blood to the front (anterior wall) and part of the side (anterolateral wall) of the left ventricle, to the top of the left ventricle, and to most of the wall between the ventricles (interventricular septum).

The Cardiovascular System (Structure and Function) (Nursing) Part 2 Coronary Arteries. Heart muscle requires its own blood supply because heart tissue does not absorb blood from its chambers. Therefore, two coronary arteries (right and left) branch off the ascending aorta to provide blood to heart muscle (Fig. 22-5). Their openings (orifices) lie behind two cusps of the aortic valve. They receive their blood supply during ventricular relaxation, when the valves are closed.

Anatomy and Function of the Coronary Arteries The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium). The left main coronary artery divides into branches: The left anterior descending artery, which branches off the left coronary artery and supplies blood to the front of the left side of the heart.The circumflex artery, which branches off the left coronary artery and encircles the heart muscle. This artery supplies blood to the lateral side and back of the heart.ince coronary arteries deliver blood to the heart muscle, any coronary artery disorder or disease can have serious implications by reducing the flow of oxygen and nutrients to the heart, which may lead to a heart attack and possibly death.

Coronary Arteries and Heart Disease Function of the Coronary Arteries. The coronary arteries supply oxygenated and nutrient filled blood to the heart muscle. There are two main coronary arteries: right coronary artery and left coronary artery. Other arteries diverge from these two main arteries and extend to the bottom portion of the heart.

Heart Anatomy Coronary Arteries. Coronary arteries supply blood to the myocardium and other components of the heart. The first portion of the aorta after it arises from the left ventricle gives rise to the coronary arteries. There are three dilations in the wall of the aorta just superior to the aortic semilunar valve.

Coronary circulation The left coronary artery distributes blood to the left side of the heart, the left atrium and ventricle, and the interventricular septum. The circumflex artery arises from the left coronary artery and follows the coronary sulcus to the left. Eventually, it will fuse with the small branches of the right coronary artery.s the left and right coronary arteries run on the surface of the heart, they can be called epicardial coronary arteries. These arteries, when healthy, are capable of autoregulation to maintain coronary blood flow at levels appropriate to the needs of the heart muscle.
