G23/1 CT Bronchial Tree with Larynx Name
English English
and Transparent Lungs
In addition to the bronchial tree created from computer tomography data, this model shows the right and
left lungs.
The left lung consists of two lobes, an upper and a lower lobe, which are separated by a fissure that runs
obliquely (oblique fissure of lung).
The right lung, in contrast, is made up of three lobes: an upper, a middle and a lower lobe. From a poste-
rior view, only the upper and lower lobes can be seen. The wedge-shaped middle lobe is located anteriorly
between the upper and lower lobes. An oblique fissure runs posteriorly between the upper and lower lobes
and lateroanteriorly between the middle and lower lobes. A fissure running horizontally (horizontal fissure
of right lung) separates the upper and middle lobes lateroanteriorly.
Due to the transparency of the lungs and the depiction of the lobar fissures, the assignment of the segmental
bronchi to the respective lobes of the left and right lungs can be studied from the outside.
A frontal section at the entrance point level of the vessels and bronchi (hilum of lung) allows division of
the lungs.
We would like to thank Prof. Dr. med. Richard H.W. Funk, Head of the Institute of Anatomy of the Medical
Department Carl Gustav Carus, Dresden/Germany, for his support in developing this model.
