Extract of sample
Etiology Arteries are made up endothelium, which is the inner layer, elastic membrane layer, connective tissue layer and a smooth muscle layer. The elastic membrane is responsible for arteries expansion and contraction that allows blood to flow through them. Therefore, atherosclerosis is a disease that is occurs when the arteries are block by some deposits. These deposits may include fats, calcium, or cholesterol that gives room for blood clotting. These deposits stimulate the arterial cells to produce some harmful substances that are going to accumulate in the inner layers of the arteries. Connective tissues are formed on the cells due to the fat deposition. As the formation of these connective tissues increases, the arteries thicken and the internal channels are reduced in the size. This reduction in the internal diameter of the arteries makes the flow of oxygen delivery very low due to the slow flow of blood. This slow speed in oxygen delivery causes blood clotting. This blood clotting will cause endothelium damage. At this point, the victim is at very dangerous situation because it can result to heart attack, stroke or kidney failure (Fuster, Ross, & Topol, 2002). However, endothelium damage has been associated with very many causes. Some of the causes are referred to as non-modifiable while others are modifiable. Modifiable factors are those that can be changed by the human being (Miller & Lewis, 2003). ...
