Asthma and Your Child
What is asthma?
Asthma is a disease of the bronchial tubes (branches of the windpipe). When an asthma attack occurs, muscles around the airway tighten and mucus builds up in the lining of the airway. The airway then becomes irritated and swollen, allowing less air into the breathing passages. Asthma is not contagious but tends to run in families.
