Which term describes the passages that branch from the trachea and direct air into the lungs?

• A. Tonsill
• B. Bronch
• C. Blephar
• D. Ather

Answer: (B)

Bronchi are the passages that branch from the trachea and direct air into the lungs. The trachea splits into the right and left main bronchi, which enter each lung and continue to branch into smaller airways, forming the bronchial tree that carries air to all parts of the lungs. The root “bronch-” appears in related terms like bronchus and bronchial tubes, linking these structures together. The other options refer to unrelated structures—tonsil (lymphoid tissue in the throat), blephar (eyelid), and ather (arterial plaque)—and don’t describe the air passages.
