Asthma affects a person bronchial (pronounced: brahn-kee-ul) tubes, also known as the respiratory tract. When a person breathes normally, air is taken through the nose or mouth and then enters the trachea (windpipe), through the airways in the lungs, and finally back. But people with asthma have airways that are inflamed. This means that they swell and produce large quantities of thick mucus. They are also too sensitive, or hyperreactive, to certain things, like exercise, dust or smoke cigarettes. This hyperreactivity causes the smooth muscle surrounding the airways to tighten. The combination of airway inflammation and muscle tightening of the airways narrow and it is difficult for air to move. In most people with asthma, difficulty breathing happens periodically. When this happens, what is called an asthma attack asthma is also known as an asthma attack, flare, episode, or the aggravation.
