Wheezes indicate what underlying airway condition?

Explanation:
Wheezes are caused by air streaming through narrowed or inflamed airways, which creates a musical, whistling sound as the breath moves past constricted passages. This means the underlying issue is airways that are narrowed and/or inflamed, such as bronchoconstriction or mucus buildup. If the airways were simply dilated from relaxation of the bronchial smooth muscle, you'd expect easier airflow and typically less or no wheeze. Fluid in the alveoli produces crackles rather than wheezes, and an absence of airflow can lead to a quiet chest, not the characteristic wheezing sound.
