I want to know the answer to the following question:
What part of the airway does asthma affect?
All the background I'm provided with is that "Unlike these diseases, the airway obstruction in asthma is usually reversible; however, if left untreated, the chronic inflammation from asthma can lead the lungs to become irreversibly obstructed due to airway remodeling.". Is that enough to answer the question?
Answer: no
