Aim: How does the respiratory system malfunction?

Diseases Asthma Bronchitis Emphysema Lung Cancer Pneumonia

Smoking Cigarette smoke contains nicotine, CO, and tar. Smoking paralyzes the cilia in the respiratory tract, preventing harmful particles and mucus from being swept out. Also causes swelling and inflammation of the respiratory surfaces.

4000 Chemicals found in cigarette smoke, 60 are known carcinogens Toluene (also found in paint thinner. Toluene (also found in paint thinner. Arsenic (deadly poison, used in pesticides) Arsenic (deadly poison, used in pesticides) Butane – (flammable, used in lighters, also in gas) Butane – (flammable, used in lighters, also in gas) Cadmium – causes damage to liver, kidney, and brain – stays in body for years. Cadmium – causes damage to liver, kidney, and brain – stays in body for years. Ammonia – helps you absorb nicotine Ammonia – helps you absorb nicotine Formaldehyde – causes cancer –used to preserve dead bodies Formaldehyde – causes cancer –used to preserve dead bodies Lead – stunts growth, makes you vomit, causes brain damage. Lead – stunts growth, makes you vomit, causes brain damage. Acetone – nail polisher remover ingredient Acetone – nail polisher remover ingredient

Asthma Allergic reaction Bronchial tubes become constricted because of swelling. Oxygen can’t get into the lungs. Worsened by smoke and pollution TREATEMENT: Inhaler

Bronchitis Inflammation of the bronchial tubes (swollen and clogged with mucus) Caused by viral or bacterial infection or from inhaling irritating fumes or dust. TREATMENT: Antibiotics if bacteria caused it.

Emphysema Lung disease, alveoli lose their elasticity. Can’t hold as much air. TREATMENT: No cure, damage can’t be undone.

Lung Cancer Uncontrolled cell growth leading to tumors in the lungs. Uncontrolled cell growth leading to tumors in the lungs. Smoking is a cause Smoking is a cause

Pneumonia Alveoli become filled with fluid and gas exchange is prevented. Caused by a viral or bacterial infection TREATEMENT: Antibiotics if bacterial
