Which of the following are pathologic alterations found with emphysema?
1) Air trapping and hyperinflation
2) Mucus plugs
3) Decreased surface area for gas exchange
4) Weakened respiratory bronchioles

Question

Quizplus · Accepted Answer

Emphysema is characterized by air trapping and hyperinflation due to the destruction of alveolar walls, leading to decreased surface area for gas exchange. The weakening of respiratory bronchioles also contributes to the disease's pathology. Mucus plugs are more characteristic of chronic bronchitis, another type of chronic obstructive pulmonary disease (COPD), rather than emphysema specifically.
