What is this article about?
In the event of an asthma attack, triggering stimuli cause the smooth muscles of the bronchi to contract and, consequently, the passage to narrow. The tissue lining of the airway swells as a result of inflammation and secretes mucus. A minor asthma attack can be treated at home with proper medications. A severe asthma attack requires medical intervention and has the potential to be a life-threatening emergency.
