The pathophysiology of chronic bronchitis can be explained by which of the following descriptions?
A) Inflammation of airways with bronchial smooth muscle spasm,vascular engorgement,increased vascular permeability,and production of thick tenacious mucus
B) Increase in the number and size of mucous glands and goblet cells in airway epithelium
C) Abnormal permanent enlargement of gas exchange airways with destruction of alveolar walls

Question

Quizplus · Accepted Answer

Chronic bronchitis is characterized by an increase in the number and size of mucous glands and goblet cells in the airway epithelium, leading to excessive mucus production and narrowing of the airways. Inflammation, smooth muscle spasm, and alveolar damage are also seen, but they are not the primary pathophysiology of chronic bronchitis. Edema in the alveoli is not a feature of chronic bronchitis.
