Which term describes a disease that destroys lung tissue and causes breathing difficulties?

• A. Bradypnea
• B. Cilia
• C. Bronchoscope
• D. Emphysema

Answer: (D)

Emphysema describes a disease in which the walls of the air sacs (alveoli) are damaged and air spaces become enlarged. This destruction of lung tissue reduces the surface area for gas exchange and causes air trapping, leading to progressive breathing difficulties, especially with activity. The other terms do not describe a disease of lung tissue: bradypnea means abnormally slow breathing, cilia are the hair-like structures that move mucus out of the airways, and a bronchoscope is a tool used to look inside the airways. Emphysema best fits the description of tissue destruction causing breathing problems.
