IGCSE Biology : U2 : Smoking
Cancers : Head, Neck, Lung, Leukaemia, Stomach, Kidney, Pancreas , Colon, Bladder and Cervix
Chronic Diseases : Stroke, Blindness, Gum Infection , Aortic Rupture, Heart disease, pneumonia, Hardening of the arteries, Chronic lung disease, asthma , reduced fertility, Hip fracture
Lung Conditions :
Lung Cancer
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
Tar irritates the lining producing overproduction of mucus which cant be cleared
A smoker develops a heavy cough to remove this called smokers cough and chronic bronchitis
