Final answer:
During an asthma attack, the airways narrow, hampering the flow of air and making breathing difficult. This is caused by a combination of factors, including bronchospasms, inflammation, and increased mucus production.
Step-by-step explanation:
Asthma is a chronic disease characterized by inflammation and edema of the airway, and bronchospasms (that is, constriction of the bronchioles), which can inhibit air from entering the lungs.
In addition, excessive mucus secretion can occur, which further contributes to airway occlusion.
