Using the provided diagram, identify the structure labeled as #3.
Bronchial tree
Bronchioles
Alveoli
Bronchi
The Correct Answer is D
A. Bronchial tree: The bronchial tree refers to the entire system of airways including the trachea, bronchi, and bronchioles.
B. Bronchioles: Bronchioles are smaller airways that arise from bronchi and do not contain cartilage. They are located further down the respiratory pathway, closer to labels #5 or #6.
C. Alveoli: Alveoli are the tiny air sacs at the very end of the respiratory tract where gas exchange occurs. They are shown at label #7, not #3.
D. Bronchi: Bronchi are the major air passages that branch off from the trachea. Label #3 is pointing to a structure at this level-larger than bronchioles but smaller than the trachea. It is one of the primary or secondary bronchi.
