BLOOD CIRCULATION [pic] CORONARY ARTERY The heart muscle receives blood to meet its metabolic needs through the coronary arterial system. The coronary arteries originate from an area on the aorta just beyond the aortic valve. Coronary arteries are blood vessels that provide oxygen-rich blood and other nutrients to the heart muscle. The coronary arteries attach to and wrap around the heart’s surface. The main coronary arteries are the left coronary artery and the right coronary artery. The

the Location of Acute Myocardial Infarctions” by Rahel Alemu‚ Eileen Fuller‚ John Harper and Mark Feldman it has become ostensible that smoking cigarettes increases the risk for acute myocardial infarctions. While smoking is a major risk factor in coronary heart disease as well as one of the major predictors of leading to myocardial infarctions. However there was not an awareness that smoking lead to different types of myocardial infarctions as in the difference between an anterior or an inferior myocardial

lungs for new oxygen; the left side of the heart receives blood rich in oxygen from the lungs and pumps it through the arteries to the various parts of the body. Circulation begins early in fetal life. It is estimated that a given portion of the blood completes its course of circulation in approximately 30 seconds. Pulmonary circulation is where the blood from the entire body is transported to the right auricle through two large veins. The superior vena cava and the inferior vena cava. When the
