Lung tissue may be removed to identify the primary and secondary bronchi. Note that the right primary bronchus is more vertical in orientation and wider in diameter than the left bronchus (Figure 19.8).

With a model of the trachea and bronchi, study the branching of the right and left bronchi:

Right principal (primary) bronchus
upper lobar (secondary)
apical segmental (tertiary)
anterior segmental (tertiary)
posterior segmental (tertiary)
middle lobar (secondary)
medial segmental (tertiary)
lateral segmental (tertiary)
