The trachea splits into which structures?

The trachea splits into which structures?

• A. Bronchioles
• B. Esophagus
• C. Bronchi
• D. Trachea

Answer: (C)

Airways divide into two main pathways after the trachea: the two primary bronchi. The trachea ends at the carina, where it splits into the right and left main bronchi that carry air into each lung. From there, each main bronchus branches further into smaller bronchi and eventually into bronchioles. The esophagus lies behind the trachea and carries food, not air, so it isn’t part of this division. Bronchioles come later as the airways get progressively smaller, so the trachea does not split into bronchioles.
