What causes veins to appear close to surface. why do bruise marks appear for unkown reasons?
Superficial vein is a term used to describe a vein that is close to the surface of the body. It is used to differentiate veins that are close to the surface from veins that are far from the surface, known as deep veins. Superficial veins are important physiologically for cooling of the body. When the body is too hot the body shunts blood from the deep veins to the superficial veins, to facilitate heat transfer to the surroundings. Superficial veins can be seen under the skin.
Are veins or arteries more superficial in the body?
Veins tend to be more superficial, meaning they lie closer to the surface of the skin. Arteries usually, but not always, run deeper in the tissue than veins.
What is a superficial vein in the leg?
The superficial veins of the legs connect to the deep veins through "penetrating veins" which run perpendicular to the skin from one to the other. The deep veins are essentially a column of blood running from your head to you feet and so when one is standing are under high pressure. In order to keep this pressure away from the frail superficial veins the penetrating veins have valves. When one of these valves goes bad the high pressure is allowed to go back to the superficial veins which blow up like balloons and become visible as what we call varicose veins (or "spider veins").

Deep veins will distend also, but not as much due to the increased pressure on them. superficial veins are under much less pressure being closer to the surface and away from muscles, so the distension is much more obvious.
