Coronary Vessels Anatomy

The right coronary artery courses in. Anastamoses can potentially occur between the arteries within the atrioventricular groove the interventricular and conus branches.

Most of the blood of the coronary veins returns through the coronary sinus.

Coronary vessels anatomy. The left main coronary artery supplies blood to the left side of the heart muscle the left ventricle and left atrium. The great cardiac vein the middle cardiac vein the small cardiac vein. The typical configuration consists of two coronary arteries a left coronary artery lmca and a right coronary artery rca arising from the left and right aortic or coronary sinuses respectively in the proximal ascending aorta.

The coronary arteries originate as the right and left main coronary arteries which exit the ascending aorta just above the aortic valve coronary ostia. These are the only two branches of the ascending aorta. Learn now at kenhub the causes and risks of the coronary artery disease as well as other common disorders of the coronary vessels.

The right coronary artery arises from the anterior sinus of valsalva and courses through the right atrioventricular av groove between the right artium and right ventricle to the inferior part of the septum. The left main coronary divides into branches. The major vessels of the coronary circulation are the left main coronary that divides into left anterior descending and circumflex branches and the right main coronary artery.

The coronary system is comprised of arteries arterioles capillaries venules and veins. The left main coronary artery has a short common trajectory branching into the left anterior descending artery and the circumflex artery. The anatomy of the veins of the heart is very variable but generally it is formed by the following veins.

There are two coronary arteries the right coronary artery and the left coronary artery which emerge from the ascending aort from the right and left aortic sinuses respectively. The left anterior descending artery branches off the left coronary artery and supplies blood to the front of the left side of the heart. The circumflex artery branches off the left coronary artery and encircles the heart muscle.

Heart veins that go into the coronary sinus. The coronary arteries are essentially functional end arteries though some anastomoses exist at the arteriolar level. Diagrams quizzes and worksheets of the heart learn all about the structure of the heart with our downloadable labelled and unlabelled worksheets.

The left and right coronary arteries originate at the base of the aorta from openings called the coronary ostia located behind the aortic valve leaflets.
