Document Summary
Veins are unlike arteries in that they are 1)superficial, 2) display dark red blood at skin surface and 3) have no pulsation. Tunica adventitia the outer layer of the vessel. Contains the arteries and veins supplying blood to vessel wall. Tunica media the middle layer of the vessel. The vasoconstrictive response occurs at this layer. Tunica intima the inner layer of the vessel. More in lower extremities and longer vessels.
