Atherosclerosis is a slow, progressive disease that may start as early as childhood. In blood vessels snaking throughout the body — circulating blood to organs and extremities — the endothelial lining acts as a filter and a wall. Endothelium is a single layer of squamous endothelial cells that line the interior surface of blood vessels, and lymphatic vessels. Epithelium is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. The blood vessels make up the body’s internal ‘road’ network linking the heart to all the organs and tissues of the body that the blood needs to reach.
