Question

How is the respiratory system affected by asthma?

Answer 1

Asthma:

1. It is a chronic disease that affects the lungs airways.
2. The muscular wall tightens and the lining of the airways swells and inflames during asthma.
3. These changes lead to a shrinking of the airways, which is made worse by an increase in mucus membrane secretions, which may actually block the narrowed airway.
4. Because inflamed airways are so sensitive, factors like smoke or dust can cause the muscles surrounding them to stiffen up.
5. This could make breathing hard and cause coughing, wheezing when you breathe, and breathlessness.
