Question

emphysema
answers: a - e
a the windpipe
b a disease that progressively destroys the walls of the alveoli
c the main airways that reach into each lung
d an inflammatory condition in which trachea, bronchi, and bronchioles become narrowed
e a muscle that separates the chest from the abdominal cavity

Explanation:

To solve this, we recall the definition of emphysema. Emphysema is a respiratory disease that affects the alveoli (tiny air sacs in the lungs) by progressively destroying their walls. Let's analyze each option:

• Option A: The windpipe is the trachea, not emphysema. Eliminate A.
• Option B: Matches the definition of emphysema as it describes a disease destroying alveoli walls.
• Option C: The main airways into lungs are bronchi, not emphysema. Eliminate C.
• Option D: Describes a condition like asthma or bronchitis (narrowing of airways), not emphysema. Eliminate D.
• Option E: The muscle separating chest and abdomen is the diaphragm, not emphysema. Eliminate E.

Answer:

B. a disease that progressively destroys the walls of the alveoli
