This model contains a natural swine lunge that was preserved by a special technology to be long lasting, odour free and flexible. The Lung is fixed on a stand and can be inflated by a supplied pump. This impressive model is very close to the human anatomy and provides an incredible possibility to see how a real lung inflates and deflates. Supplied with a lung cross section to see the internal structure. Lung model as R10060, but this lung was stained realistically before the preservation process. It looks like a real smokers lung and works like the model R10060. Supplied with smokers lung cross section, stand and pump.
