Asthma- A condition in which a person's airways become inflamed, narrow and swell, and produce extra mucus, which makes it difficult to breathe.
Asthma attack- Called an asthma exacerbation, the airways become swollen and inflamed. The muscles around the airways contract and the airways produce extra mucus, causing the breathing (bronchial) tubes to narrow.
