The blood vessels in the heart.
Two main arteries, arising from the aorta, arching down over the top of the heart, and carrying blood to the heart muscle.
The two large arteries that supply blood to the heart muscle. Impairment or blockage of one or more of these arteries can lead to a heart attack.
The arteries supplying blood to the heart. The right and left coronary arteries arise from the aorta, just above the aortic valve, and form branches that encircle the heart.
The right coronary artery arises from the right aortic sinus and passes into the right atrio-ventricular groove to supply the right ventricle, part of the intraventricular septum and the inferior part of the left ventricle. The left coronary artery arises from the left sinus and divides into an anterior descending branch which supplies the septum and the anterior and apical parts of the heart, and the circumflex branch which passes into the left atrio-ventricular groove and supplies the lateral posterior surfaces of the heart. Small anastomosesexist between the coronary arteries and they have the potential of enlarging if the blood-flow through a neighbouring coronary artery is compromised. Coronary artery disease is damage to the heart caused by the narrowing or blockage of these arteries. It commonly presents as angina pectoris or acute myocardial infarction.
The arteries that carry blood to the heart muscle.
The two arteries that wrap around the upper portion of the heart in a crown-like manner.
