Coronary circulation Coronary vessel branches that remain on the surface of the artery and follow the sulci of the heart are called epicardial coronary arteries. 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.

Heart Anatomy Coronary veins drain the heart and generally parallel the large surface arteries (see [link]). The great cardiac vein can be seen initially on the surface of the heart following the interventricular sulcus, but it eventually flows along the coronary sulcus into the coronary sinus on the posterior surface.

Right coronary artery Right coronary artery. In the coronary circulation, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the heart. It travels down the right coronary sulcus, towards the crux of the heart. It branches into the posterior descending artery and the right marginal artery. Although rare, several anomalous courses of the right coronary artery have been described including origin from the left aortic sinus. At the origin of the RCA is the conus ...

- The two main coronary arteries are the left main and right coronary arteries. Left main coronary artery (LMCA). 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.

Human Physiology/Print Version Coronary arteries supply blood to the myocardium and other components of the heart. Two coronary arteries originate from the left side of the heart at the beginning (root) of the aorta, just after the aorta exits the left ventricle.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.

Anatomy and Function of the Coronary Arteries 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. Together with the left anterior descending artery, the right coronary artery helps supply blood to the middle or septum of the heart.

Left main coronary artery originating from the right sinus of valsalva and coursing between the aorta and pulmonary trunk Discussion Classification of the anomaly. Anomalous origin of the left main coronary artery from the right sinus of Valsalva can be classified into four major groups according to the course taken by the left main artery in relation to the aorta and pulmonary trunk en route to the left side of the heart.

Meet the Host, Neil Shubin Yes. When I was writing Your Inner Fish, I realized there was this whole other story, about our connection to the physical world — plate tectonics, the planets, the universe. These are also passions of mine and other chapters in the same story.he most remarkable is the hand. It's a physical manifestation of our ability to go to the bottom of the ocean and into outer space. If you trace fossils and genes in different species, you see how our arms, legs, hands and feet are just repurposed fish fins.

Heart Anatomy The aorta is the major blood vessel that arises from the left ventricle and is separated from it by the aortic valve. The left main coronary artery arises from above the left portion of the aortic valve and then usually divides into two branches, known as the left anterior descending (LAD) and the circumflex (Circ) coronary arteries. In some patients, a third branch arises in between the LAD and the Circ. This is known as the ramus (pronounced ray-muss), intermediate , or optional diagonal coronary artery. The LAD travels in the groove (known as the inter-ventricular groove) that runs in the anterior or front portion the heart.

great cardiac vein great cardiac vein, one of the five tributaries of the coronary sinus, beginning at the apex of the heart and ascending along the anterior interventricular sulcus to the base of the ventricles. It then curves left in the coronary sulcus, reaches the back of the heart, and opens into the left part of the coronary sinus.

- Go to the U of M home page. Location: The left coronary artery (left main coronary artery) emerges from the aorta through the ostia of the left aortic cusp, within the sinus of Valsalva. The plane of the semilunar valve is tilted so that the ostium of the left coronary artery is superior and posterior to the right coronary ostium. The left coronary artery travels from the aorta, and passes between the pulmonary trunk and the left atrial appendage.

Circumflex artery Circumflex artery. The circumflex artery, fully titled as the circumflex branch of the left coronary artery, is an artery that branches off from the left coronary artery to supply portions of the heart with oxygenated blood. The circumflex artery itself divides into smaller arterial systems.
