Three Reactions When An Asthma Sufferer Meets Up With a Trigger?

The first reaction:
This occurs when the muscles encircling the bronchial air passages squeeze the passages, thus reducing the flow of air. It is known as bronchospasms or bronchial spasms.

The second reaction:
The cells along the bronchial airway walls produce a large amount of thick,gummy mucus. The mucus collects along the bronchial walls,thus narrowing the airways. In more severe asthma attacks,the mucus may form sticky plugs that clog the air passages.

The third reaction:
The linings of the bronchial tubes-the mucosa-became inflamed,which makes the airways puffy and swollen .The swelling narrows the airways ,restricting the amount of air that can pass through.

In short,an asthma attack is a period of breathing difficuly exhibiting three factors-bronchospasms,mucus production and inflammation.Asthma attacks may last several minutes or go on for hours or even days. The longer an attack persists, the more dangerous it becomes.
