Draw the anatomy of the right sided bronchial tree

RUL=3=apical/ant/post
bronchus intermedius
RML=2=med/lateral
RLL=5=apical/ant/post/lat/medial

RUL=3=apical/ant/post


bronchus intermedius


RML=2=med/lateral


RLL=5=apical/ant/post/lat/medial

draw the bronchi view you would get at the carina, looking down the right proximal main bronchus..


what is special about RUL.

R Main is short-2-3cm.  
RUL comes off at 3oclock. 
RUL is ONLY primary branch from main bronchus where you will see 3 divisions 
bronchus intermedius continues on. 
Trachealis muscle continues down B intermedius

R Main is short-2-3cm.


RUL comes off at 3oclock.


RUL is ONLY primary branch from main bronchus where you will see 3 divisions


bronchus intermedius continues on.


Trachealis muscle continues down B intermedius

draw the view you will get at bronchi intermedius.

The right middle lobe bronchus comes off at the top (12 o'clock)


under it is the right lower lobe bronchus.


this has a proximal branch at 6 o'clock (apical segment) and then goes down to the other 4 segments.

outline the anatomy of the left sided bronchial tree.


how is it similar/different to the right side.

left is mirror image of right except only 2 main lobes.


instead of upper/middle/lower it has upper (with 2 subsegments the superior and lingular) and a lower.


both R+L upper lobes = 3 subunits (apical/post/ant)


Both R middle + L lingular = 2 subunits


Both lower lobes=5 sub units=apical, medial, lateral, post, ant. but left often has fused ant medial.



Draw the left anatomy.

at the upper lobe bifurf, the superior seg comes off at 12, the lingular at 6.

at the upper lobe bifurf, the superior seg comes off at 12, the lingular at 6.

draw the whole tree anatomy
