Primary Bronchi are to ________ as Secondary Bronchi are to ________

Question

Primary bronchi are to ________ as secondary bronchi are to ________.
A) main bronchi; lobar bronchi
B) lobar bronchi; segmental bronchi
C) segmental bronchi; lobar bronchi
D) trachea; pharynx
E) lobar bronchi; alveolar ducts

Accepted Answer

The primary bronchi branch off from the trachea and lead to the lungs, while secondary bronchi branch off from the primary bronchi and lead to the lobes of the lungs. Lobar bronchi are also known as secondary bronchi, while segmental bronchi are also known as tertiary bronchi. Therefore, choice A correctly matches main bronchi (primary) with lobar bronchi (secondary).
