When you are not having asthma signs, your airways are apparent. Air can conveniently move in and out of your lungs.
When an asthma attack begins, the smooth muscle groups all over the exterior of the tubes may perhaps tighten. The airways, or bronchial tubes, in the lungs turn into infected and swollen.
This makes it tough for air to go by way 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 may perhaps outcome in a wheezing seem and shortness of breath — indicators and signs of an asthma attack.
