Asthma: Lungs
built 658 days ago
Asthma is a chronic lung disease characterized by recurrent episodes of wheezing, breathlessness, chest tightness and coughing. Pulmonary inflammation contributes to the bronchoconstriction that can precipitate an asthma attack, and to the progression of this chronic disease.

Asthma affects the airways of the lungs (the bronchi) which causes the airways to become inflamed and swollen. The bronchi are small tubes that carry air in and out of your lungs. If you have asthma, the bronchi are more sensitive than normal and certain substances, or triggers, can irritate them.
