Arteries and Veins 3D structural simulator

■  The enlarged anatomical simulator of arteries and veins displays the three-dimensional structure of arteries and veins. The three-layer membrane of arteries is thicker than that of veins, and arteries have inner and outer elastic membranes. However, the smooth muscle and elastic tissue of veins are not as good as those of arteries. The venous foramen are larger than those of arteries, and veins have valves.
