Cigarette smoking is associated with a wide variety of abnormalities throughout the body that cause not only illness, but also, all too often, death. Indeed, if all deaths from diseases related to smoking (lung disease, heart disease, and cancers of many different organs) were considered, a case could be made for cigarette smoking as the leading cause of death in industrialized countries. Ironically, it is also the most preventable cause of death in our society!

➡ ALVEOLI :- Alveoli are the tiny air sacs (only 1 cell thick) in the lungs at the end of the smallest airways, where the exchange of oxygen and carbon dioxide takes place. The average human has nearly 300 million alveoli to absorb oxygen from the air.

1. alveoli is present in lungs and exchanges gas.

2. it is related to respiration.

3. Without the alveoli, respiration would not be possible. 

4. When a person breathes, air enters their body through the trachea. 

5. The air is then separated by the bronchi, which leads the air into both lungs.

6. the bronchi tubes, the air travels through a network of tunnels inside the lungs. At the end of each air tunnel is an alveoli sacs.

7. When air enters into the alveoli sac, the blood vessels around the sac absorb the air immediately.

8. Whatever gas is breathed in goes through the sac and is absorbed into the blood. 

9. The blood immediately separates the oxygen from the other gases in the air, most notably carbon dioxide.

10. Simultaneously, the carbon dioxide is pushed back into the alveoli where, in the act of exhaling, the carbon dioxide is removed from the body.
