Asthma

A common disorder in which chronic inflammation of the bronchial tubes (bronchi) makes them swell, narrowing the airways. Asthma involves only the bronchial tubes and does not affect the air sacs (alveoli) or the lung tissue (the parenchyma of the lung) itself.

Airway narrowing in asthma is due to three major processes acting on the bronchi: inflammation (see above), spasm (bronchospasm), and hyperreactivity (over-reaction of the bronchi to factors that can precipitate asthma).
