Question

which of the following conditions results from the buildup of scar tissue on the lungs, which makes the lungs less elastic?
○ asthma
○ stroke
○ emphysema
○ bronchitis

Explanation:

To solve this, we analyze each option:

• Asthma: Involves airway inflammation/spasms, not lung scarring.
• Stroke: Affects the brain, unrelated to lung tissue.
• Emphysema: Caused by damage (including scarring) to lung alveoli, reducing lung elasticity.
• Bronchitis: Inflammation of bronchial tubes, not lung scarring leading to reduced elasticity.

Answer:

Emphysema (the option with "Emphysema" as the text, from the list of options provided: the third option in the list, which is "Emphysema").
