Your lungs

An asthma attack occurs when the airways of the lung become narrowed causing an obstruction to the flow of air. Symptoms include coughing, wheezing, breathlessness and a tightness in the chest.

During an asthma attack the muscle wall contracts and the lining of the airways becomes swollen and inflamed, these changes cause the airways to narrow.
