Question

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

Explanation:

To solve this, we analyze each option:

• Option A describes emphysema (destroys alveoli walls), not bronchi.
• Option B: Bronchi are the main airways branching into each lung from the trachea, so this matches.
• Option C describes a condition like asthma or bronchitis (narrowing of airways), but not the definition of bronchi.
• Option D describes the diaphragm, not bronchi.
• Option E describes the trachea (windpipe), not bronchi.

Answer:

B. the main airways that reach into each lung
