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.

The reason that it is more likely to occur in the legs is that there is a greater fluid pressure caused by gravity's effect on the column of blood within your body.
