Why Is Venous Pressure Lower Than Arterial? Compared with arteries, the tunica media of veins, which contains smooth muscle or elastic fibers allowing for contraction, is much thinner, resulting in a compromised ability to deliver pressure. Why is blood pressure lower in veins than arteries? Arteries have thick walls so they can handle the high

What Causes Stasis? What causes stasis? Stasis dermatitis is caused by venous hypertension resulting from retrograde flow related to incompetent venous valves, valve destruction, or obstruction of the venous system. The ensuing inflammatory process is mediated by metalloproteinases, which are up-regulated by ferric ion from extravasated red blood. What causes stasis of blood flow? There
