The size of blood vessels corresponds with the amount of blood that passes through the vessel All blood vessels contain a hollow area called the lumen through which blood is able to flow Around the lumen is the wall of the vessel, which may be thin in the case of capillaries or very thick in the case of arteriesArtery and Vein TS Perspective view Blood flows away from a body`s heart via arteries, which branch and narrow into arterioles, and then branch further still Histopathology of hypertensive renal disease, light micrograph Photo under microscope, hypertony, hypertonic, vessel, artery, vein, capillary, high, bloodConsequently, arteries tend to maintain their round shape better than veins in histological sections Veins also contain valves to prevent back flow of blood but these are infrequent and are not reliably seen in histological samples Small Artery and Venule Vena Cava This image shows the wall of the vena cava, which is the largest vein in the

Artery vein capillary image- Once blood is oxygenated in the lungs, it returns to the heart and is then pumped throughout the body A web of blood vessels—arteries, veins, and capillaries—circulate blood to Arteries and veins have the same layers of tissues in their walls, but the proportions of these layers differ Lining the core of each is a thin layer of endothelium, and covering each is a sheath of connective tissue, but an artery has thick intermediate layers of elastic and muscular fiber while in the vein, these are much thinner and less developed
