Segmented Lung, 20 parts
This “Thoracic Organs with Segmented Lungs” model shows the organs and structures of the chest cavity.
These include the right and left lungs and the pulmonary lobes, heart, pericardium, the large vessels around
the heart and the trachea with oesophagus. The lung segments can be taken apart; inside the lungs, the seg-
mental bronchi are shown in different colours. Located under the chest cavity structure are the diaphragm
and the associated section of the pleura. The anatomical structures behind the oesophagus and the thoracic
aorta have been cut horizontally at the level of the lower thoracic spine.
As well as depicting the organs and structures of the thoracic cavity, this model helps to provide a better
understanding of the lung segments as isolated components of the individual lobes, each with its own seg-
mental bronchus. It is very important to be able to examine and identify all segments of the anatomy using
bronchoscope and radiological methods as any section may become diseased requiring diagnosis and speci-
fically targeted treatment or surgery.
