When you happen to be not getting asthma indicators, your airways are apparent. Air can conveniently circulation in and out of your lungs.
When an asthma attack begins, the easy muscle groups about the outside of the tubes might tighten. The airways, or bronchial tubes, in the lungs turn out to be infected and swollen.
This helps make it tough for air to go as a result of the opening. The mucous membrane lining in the tubes begins to develop thick mucus, which builds up and even more blocks the airways.
This tightened airway might outcome in a wheezing seem and shortness of breath — indications and indicators of an asthma attack.
