Why is air flow restricted djuring an asthmatic attack?

During an asthmatic attack, air flow is restricted primarily due to inflammation and swelling of the airways, which narrows the bronchial passages. Additionally, increased mucus production can further obstruct airflow, and the muscles surrounding the airways may constrict, compounding the difficulty in breathing. Together, these factors lead to the characteristic wheezing and shortness of breath experienced during an Asthma attack.
