  • Chronic Bronchitis

  • Emphysema - When alveoli are not as elastic


Carcinogens - Things which cause cancer

Carcinogenic - Things which describe cancer


Emphysema : 

  • Damages alveoli walls, they burst and fuse together

  • Reduces the surface area of gaseous exchange 

  • Unable to carry out basic tasks like walking

  • There is no cure


Chronic Bronchitis : 


  • The tar in cigarettes damages and paralysis cilia cells 

  • Bacteria builds up and you can get chest infections
