Asthma is a very common disease. It is characterized by widespread narrowing of the bronchioles and formation of mucus plugs, producing symptoms of wheezing, shortness of breath, and coughing, and is caused by the release of factors during an allergic response. Explain why the narrowing of bronchioles, rather than that of the larger bronchi, is the source of the airflow restriction, and why inhaling dilating agents can bring relief during an asthma attack.
