Diseases

Associated with Air Pollution

chronic bronchitis
Chronic Bronchitis

Occurs when cilia that lines the bronchial tubes are damaged

Normally sweep mucus with trapped particles and germs out of the bronchial tubes

Cells produce more and sometimes thicker mucus than normal

Mucus interferes with the exchange of air

bronchial asthma
Bronchial Asthma

Allergic reaction of the membranes lining the bronchial tubes

Membrane wells causing passage to narrow

Smooth muscles in the walls of the bronchial tubes sometimes spasm

The spasms close the tube, causing an asthma attack

emphysema
Emphysema
  • Results after years of irritation
  • Air sacs of the lungs lose their elasticity
  • No longer have the ability to push air out of the lungs
  • Oxygen and carbon dioxide cannot diffuse across the damaged membranes as easily
pneumonia
Pneumonia

Infections occur more often when pollutants kill the bacteria-destroying cells, which normally line the respiratory tract

More mucus is produced in response to the pollutant

Excess mucus limits the exchange of air and prevents the cilia from sweeping bacteria and other particles out of the lungs

lung cancer
Lung Cancer

Cell division goes haywire

Inhaled smoke and other pollutants cause normal cells to develop into cancerous cells

Cells grow and divide in an unusually fast rate

Air cannot easily diffuse across the cancer cells
