The walls of all arteries are composed of three layers: the tunica intima, tunica media and tunica adventitia, which are arranged one on top of the other like the layers of an onion. ‘Tunica’ simply means ‘coat. ‘The 2 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 divides into branches:
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. This artery supplies blood to the outer side and back of the heart.
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. Together with the left anterior descending artery, the right coronary artery helps supply blood to the middle or septum of the heart.
The arteries are the highway system of the body. They provide an extensive network throughout the body to transport needed supplies to the cells and eliminate waste products. Arteries come in a variety of sizes that range from the large aorta in the chest to small capillaries found within the lungs.
Particles of cholesterol, fat, and other cells build up in arteries—thanks mostly to a Western diet loaded with meat, dairy products, and eggs—they create fatty streaks and eventually form plaques that obstruct blood flow.
In coronary artery disease—the most common type of cardiovascular disease and leading killer in the United States—these blockages affect the arteries leading to the heart, causing chest pain and often resulting in heart attack. But blockages do not only affect the arteries in the chest. Atherosclerosis, or the thickening of arteries, can strike any artery in the system, leading to different symptoms throughout the body that can serve as early warning signs for cardiovascular disease.
