Bronchi

A physician should absolutely know the anatomy of the bronchi. Look at the drawing on the left and compare it to the chest x-ray on the right. You can see that the major bronchi are visible if you look carefully. It may be beneficial to practice drawing the bronchi and labeling them until you are entirely familiar with their names and locations. The table below shows the segmental bronchi and their designated numbers.

A = Right Main Stem Bronchus
B = Right Upper Lobe Bronchus
  B1 = Apical Segmental Bronchus
  B2 = Anterior Segmental Bronchus
  B3 = Posterior Segmental Bronchus
C = Bronchus Intermedius
D = Right Middle Lobe Bronchus
  D4 = Lateral Segmental Bronchus
  D5 = Medial Segmental Bronchus
E = Right Lower Lobe Bronchus
  E6 = Superior Segmental Bronchus
  E7 = Medial Basal Segmental Bronchus
  E8 = Anterior Basal Segmental Bronchus
  E9 = Lateral Basal Segmental Bronchus
  E10 = Posterior Basal Segmental Bronchus
F = Left Main Stem Bronchus
G = Left Upper Lobe Bronchus
  G1, G2 = Apicoposterior Segmental Bronchus
  G3 = Anterior Segmental Bronchus
H = Lingular Bronchus
  H4 = Superior Lingular Segmental Bronchus
  H5 = Inferior Lingular Segmental Bronchus
I = Left Lower Lobe Bronchus
  I6 = Superior Segmental Bronchus
  I7 = Medial Basal Segmental Bronchus
  I8 = Anterior Basal Segmental Bronchus
  I9 = Lateral Basal Segmental Bronchus
  I10 = Posterior Basal Segmental Bronchus

SMALP
