EAP 1540 Cause and effect Essay

The chemicals in tobacco damage your blood cells. Also, they damage the function of heart. This one increases the risk of atherosclerosis that is a disease in which a substance called plaque builds up in heart arteries.

Lungs are the most directly affected by smoking. They are designed to provide air that contains oxygen and pass it to the blood stream. The action of smoke causes irritation of the cells lining the air tubes within the lungs. By this reason, they produce mucus that reduces the diameter of the air tubes making it more difficult to breathe. Then, this is when the smoker coughs up the mucus.
