MICRO ANATOMY, ARTERY AND VEINS (2923)
The model shows a medium-sized muscular artery with two adjacent veins from the ante-brachial area with adjoining fat tissue and muscle enlarged 14 times. The model illustrates the reciprocal anatomical relationship of artery and vein and the basic functional techniques of the venous valves ("valve function' and "muscle pump"). The left vein and the middle artery are fenestrated in the upper anterior segment, revealing the various layers of the wall structure in a cross and longitudinal section and in top view. The right vein is opened throughout in the anterior segment, revealing the orifice of a feeder vein and two venous valves, i. e. "flap valves" formed by a duplication of the tunica intima. On the rear of the model, the relief of two veins is shown to illustrate the functional aspect of the venous valves. This model mounted on a base.

LOBULE OF THE LUNG WITH ADDITIONAL MODEL PULMONARY ALVEOLI (2926)
A beautifully detailed depiction of the structures involved in gaseous exchange, the model clearly shows the alveolar epithelium, where oxygen is taken in and carbon dioxide is give off, as well as the alveoli, intact and sectioned, to reveal the capillary network. Arteries and veins are displayed with both bronchioles connecting to alveolar ducts, color-coded elastic fibers, smooth muscle, mucous membranes, and cartilage. The back of the model diagrams the circulation within the lobule and the pleura. The model is mounted on a stand and can be removed for closer examination.
