This enlarged artery and vein model (G42 / 1000278) shows a medium-sized muscular artery with two adjacent veins from the antebrachial area with adjoining fat tissue and muscle.

The circulatory system model has been enlarged 14 times to allow detailed study of 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 artery and vein model, the relief of two veins is shown to illustrate the functional aspect of the venous valves.

The 3B MICROanatomy Artery and Vein model is supplied on base. A great tool for teaching about the human circulatory system.
