ลำดับการแตกของ trachea, lobar bronchus and and segmental bronchus
Left side
Left main bronchus ให้ lobar bronchus คือ
Superior lobar bronchus และ inferior lobar bronchus

Left Superior lobar bronchus ให้สองอันย่อยคือ upper branch and lower branch
Upper branch: Apicoposterior segment of RUL, Anterior segment of RUL
Lower branch: Superior and inferior lingular segment of RUL

Left Inferior Lobar bronchus แตกต่อเป็น segmental bronchus
- Superior segment of LLL
-Anteriormedial basal segment of LLL
-Lateral basal segment of LLL
-Posterior basal segment of LLL

Right main bronchus แตกย่อยสอง branch
Right superior lobar bronchus
- Apical segment of RUL
- Anterior segment of RUL
- Posterior segment of RUL

Bronchus intermediate ซึ่งจะกลายเป็น

Right middle lobar bronchus
- Medial segment of RML
- Lateral segment of RML

Right Lower lobar bronchus
- Superior segment of RLL
- Anterior basal segment of RLL
- Lateral basal segment of RLL
- Medial basal segment of RLL
- Posterior basal segment of RLL
