BASIC SUBSTANCE OF CIGARETTES AND THEIR HARMFUL EFFECTS

The lungs are made up of approximately 350 million tiny sacs called alveoli, where carbon dioxide from the body is exchanged for oxygen from the air. Various diseases that affect the lungs either destroy the alveoli directly, as does emphysema, or impair the alveoli’s ability to exchange gases. This picture shows the effects of emphysema (caused by smoking) on lung tissue.
