In this disease the parts of the tiny airway become swell.  This disease which affects tiny tubules like structure that is the passage of oxygen and carbon dioxide.

This phenomenon is called bronchiolitis. This disease also spread to the lungs. In this disease, the oxygen and carbon dioxide track become closer when it fills up with mucus. This process creates difficulty in gaining oxygen. Generally, top time for bronchiolitis can occur during the months of winters.
