Each of our hearts have two coronary arteries: right coronary artery and the left coronary artery, the coronary arteries from the aortic root through the intermediary of the Valsalva sinus and running on the surface of the heart. Left coronary artery runs a short (1 - 3 cm) and then divided into two major branches arteries and ventricular septal artery before hat, short is called coronary artery general body. Thus, coronary artery system has three major branches task is nurturing heart: ventricular septal artery before, arteries and coronary arteries hat. From the three major branches for a lot of the smaller arteries branching tributaries walls, diagonal branch, branch shore ... will have carries oxygen-rich blood from the aorta to go nurturing all structures of the heart. When coronary artery disease, coronary blood flow to the heart muscle decreased, whereas the heart muscle does not receive enough oxygen and the onset of symptoms of angina pectoris.
