The model shows the terminal branch of the bronchial tree (Terminal bronchiolus) with its further bifurcations, the associated pulmonary alveoli, as well as the surrounding blood vessels and their capillary networks in 130-fold magnification. On the right side of the model, the pulmonary lobule is cut in order to facilitate view of the pulmonary tissue structure. The left side of the model shows a section of connective tissue located between adjacent pulmonary lobules. To better understand the gas exchange, a single opened pulmonary alveolus with the surrounding capillary network is demonstrated at the back of the model in approx. 1000-fold magnification. A graphic presentation on the base of the model shows the structure of the air passages located in the lung up to the pulmonary alveoli.
