Where the veins are located?
If you're over 40, you probably see them; those little purple veins that suddenly seem to appear on your legs. Veins are the soft, thin-walled tubes that return blood from the arms and legs to the heart. Because veins work against the force of gravity, they have valves that allow forward blood flow, but not reverse. Your legs and arms have two major types of veins: superficial and deep. The superficial veins are near the surface of the skin and are often visible. The deep veins are located near the bones and are surrounded by muscle. Connecting the deep and superficial veins is a third type of vein, the perforator vein. Contraction (squeezing) of the muscles in the arms and legs with exercise helps blood flow in the veins.Varicose veins are enlarged, bulging superficial veins that can be felt beneath the skin, generally larger than 3-mm in diameter. They are usually located on the inside of the calf or thigh and develop due to weakness of the vein wall and loss of valve function. Under the pressure of gravity, they continue to enlarge, and in the course of time, they may become elongated, twisted, pouched, and thickened.Spider veins or telangiectasia are tiny dilated, veins, usually less than 1-mm in diameter, located at the surface skin layers. Spider veins cannot be felt. Veins larger than the spider veins, but still under 3-mm are called reticular veins.

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.
