Smoker's lungs and emphysema. Coloured anterior 3D computed tomography (CT) scan of the lungs of a smoker who has developed emphysema, a form of chronic obstructive pulmonary disease (COPD). The emphysematous bullae (abnormal air pockets) are shown in blue. Cigarettes contain cancer-causing chemicals and the addictive drug nicotine. Tobacco smoke is the major cause of lung cancer and several other lung diseases such as emphysema, a disorder where the air sacs in the lungs become enlarged and damaged reducing the surface area for the exchange of oxygen and carbon dioxide. | |
