Question

Which of the following contributes to the wheezing of asthma?
A) Constriction of the bronchiolar smooth muscle
B) Edema of the esophagus
C) Inflammation of the trachea and pharynx
D) Pneumothorax

Accepted Answer

Wheezing in asthma is caused by the constriction of the bronchiolar smooth muscle, leading to decreased airflow and difficulty breathing. Edema of the esophagus, inflammation of the trachea and pharynx, and pneumothorax may cause respiratory symptoms but do not typically contribute to wheezing in asthma.
