Question

Quizplus · Accepted Answer

Wheezing is caused by the movement of air through narrowed airways, which occurs in asthma due to inflammation and constriction of the bronchioles. This causes a high-pitched whistling sound during expiration. Increased thickness of respiratory secretions, use of accessory muscles of respiration, and tachypnea and tachycardia may also be present in asthma but are not the direct cause of wheezing.
