One of the two branches formed by the division of the trachea is:
Bronchiole
Hilum
Bronchus
Conchae
The Correct Answer is C
A. Bronchioles are smaller branches of the bronchial tree that come after the bronchi. They are not formed directly from the trachea.
B. The hilum is a region on the lung’s surface where structures like bronchi, blood vessels, and nerves enter or exit—but it is not a branch of the trachea.
C. The bronchus (plural: bronchi) is one of the two primary branches that the trachea divides into—right and left primary bronchi—which lead into each lung.
D. The conchae (or turbinates) are bony structures inside the nasal cavity that help filter and humidify air, but they are not related to the branching of the trachea.
