Coronary Arteries And Cardiac Veins Anatomy And Branches

Coronary circulation is the circulation of blood in the blood vessels that supply the heart muscle.

Heart anatomy coronary arteries. Directs oxygenated blood to the left anterior descending artery and the left circumflex. The largest artery is the aorta the main high pressure pipeline connected to the hearts left ventricle. The arteries are the blood vessels that deliver oxygen rich blood from the heart to the tissues of the body.

The coronary arteries originate as the right and left main coronary arteries which exit the ascending aorta just above the aortic valve coronary ostia. Some of the arteries that extend from the main coronary arteries include. The left circumflex artery runs along the coronary sulcus between the left atrium and ventricle to the posterior side of the heart where it usually ends in an anastomosis with the right coronary artery.

Left main coronary artery lmca. Coronary artery dominance is defined by the vessel. The left main coronary artery supplies blood to the left side of the heart muscle the left ventricle and left atrium.

Right coronary artery rca. This article describes the typical course pattern and distribution of the coronary arteries and some of their respective named branches. The right coronary artery supplies blood to the right ventricle the.

The coronary arteries provide oxygenated blood to the heart. These two branches subdivide and course over the surface of the heart epicardium as they traverse away from the aorta. The aortic sinuses are small openings found within the aorta behind the left and right flaps of the aortic valve.

This article describes the typical course pattern and distribution of the coronary arteries and some of their respective named branches. There are two main coronary arteries which branch to supply the entire heart. Therefore its circulation is of major importance not only to it.

Each artery is a muscular tube lined by smooth tissue and has three layers. Because the rest of the body and most especially the brain needs a steady supply of oxygenated blood that is free of all but the slightest interruptions the heart is required to function continuously. Coronary arteries supply oxygenated blood to the heart muscle and cardiac veins drain away the blood once it has been deoxygenated.

Coronary arteries anatomy left coronary artery. The left main coronary artery is the beginning of the left coronary artery. They are named the left and right coronary arteries and arise from the left and right aortic sinuses within the aorta.

Supplies oxygenated blood to the walls of the ventricles and the right atrium. Left main coronary artery. These arteries divide into progressively smaller branches.

When the heart is relaxed the back flow of blood fills these valve pockets therefore allowing blood to enter the coronary arteries. One or more left marginal arteries obtuse marginal arteries om or left marginal branches. It originates from the right posterior aortic sinus and runs through.
