Role of Oxygen in human body and the basis for life – 5

Asthma - Asthma is a long-term, inflammatory lung disease that causes airways to tighten and narrow when a person with such inflammatory condition comes into contact with irritants such as dust, cigarette smoke, or chemicals.  Asthma can be life threatening too in some cases.

Bronchitis - Although bronchitis doesn't affect most teens, it can affect those who smoke continuously.  In bronchitis, normally the membranes lining the larger bronchial tubes become inflamed and an excessive amount of mucus is produced, so if an excess amount of mucus is produced, it is indicative but should be confirmed with a lab test.  The person with bronchitis develops a bad cough to get rid of the mucus but this is not in all the cases.

Cystic fibrosis (CF) - is an inherited disease affecting the lungs.  Cystic fibrosis causes the mucus in the body to be abnormally thick and sticky.  This mucus that is thick and sticky can clog the passage airways in the lungs and make the affected person more likely to get bacterial infections.

Pneumonia - Pneumonia is an inflammation of the lungs, which usually occurs because of infection by a bacteria or virus.  Pneumonia will cause fever, inflammation of lung tissue, and makes breathing difficult because the lungs have to work harder to transfer oxygen into the bloodstream and remove carbon dioxide from the blood, it will be strenuous task for your body to perform when you have pneumonia.  Common causes of pneumonia are influenza and infection with the bacterium Streptococcus Pneumoniae.

Although some of these respiratory diseases like asthma or cystic fibrosis can't be prevented, but you can prevent many of the chronic lung and respiratory illnesses by avoiding to smoke, staying away from pollutants and irritants, washing your hands often to avoid infection, and getting regular medical checkups.
