Christopher Nolop 1 st March 2008 Biology 14 Lab The Affects of High Density Lipids on Coronary Arteries Over 14 million Americans have coronary heart disease, the leading cause of death in the United States. Needless to say, heart disease, or specifically atherosclerosis, is a worldwide problem. To begin with, coronary atherosclerosis is the inflammatory response of the arteries to an excess of macrophage white blood cells, and cholesterol build-up along the walls of the arteries that bring blood away from the heart to the rest of the body. It begins with low-density lipoproteins (LDL’s) that carry cholesterol seeping through the arterial walls and oxidizing. The immediate inflammatory response of the body is to send hoards of white blood cells to the arterial wall in an attempt to destroy the oxidized LDL’s, but the white blood cells ultimately fail and simply amass more cholesterol and fat to the lining of the artery wall. The cholesterol forms a plaque, which induces the hardening and loss of elasticity of the arterial wall. Thus, the arteries at risk
