MICRO Anatomy Artery and Vein

The model shows a medium-sized muscular artery with two
adjacent veins from the antebrachial 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. Supplied on base.
