Question: 1 / 400

How can emphysema be described?

Swelling, inflammation, and thickening of bronchioles

Destruction of alveolar walls

Emphysema is a lung condition where the alveolar walls, which are responsible for gas exchange, are damaged or destroyed. This leads to a decrease in lung function and difficulty breathing. Option A is incorrect because it describes bronchiolitis, which is a different condition that affects smaller airways in the lungs. Option C is incorrect because it refers to a physical symptom that can be present in a variety of lung diseases, not just emphysema. Option D is incorrect because while a cough can be a symptom of emphysema, being overweight is not a defining characteristic of the disease.
