Anatomically, the model depicts both the throat (larynx), the windpipe (trachea) and the first 3 generations of the bronchial tree.
The larynx is illustrated in a particularly high degree of detail, as both cartilage, membranes and all 6 muscles are shown on the model. When the larynx is separated in the middle (in a saggital cut), both the entrance from the pharynx to the larynx (aditus laryngis) and the vocal fold (rima glottidis) are seen between the vocal folds.
The larynx continues into the trachea, which at the bifurcation of the trachea divides into a right and left main bronchus. On the left side, the main bronchus divides into 2 lobe bronchi, on the right side into 3 lobe bronchi. These are all pictured in white with bluish looking cartilage.
Each lobe bronchus divides into segmental bronchi. In each lung there are approx. 10 lung segments, each supplied by a segmental bronchus. The individual segmental bronchi are depicted in different colors to make it easier to distinguish them from each other.
