What is the meaning of veins close to the surface?
The scientific name for veins that are close to the surface is superficial veins. These are the veins you can see under your skin.
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…
Arteries are not close to the surface in most places on the body because they need to be protected. But there are many places, called endangerment sites, where they are close to the surface, so health care workers need to be cautious when working in these areas. Usually, in most place on the body arteries and veins are close together, so are nerves.
Varicose veins are caused by a defect in the valves directing one way flow inside the veins. When the valves are not functioning correctly, the blood backs up into the surface (superficial) veins and presents as varicosities. 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.
For the record I am not a doctor; however, I do believe that a superficial cut is considered a surface cut meaning a minor cut not serious. For instance, a cut on your finger from a knife that is not deep without any veins, tendons, or bone cut is a superficial cut. A superficial cut is a non emergency cut one that is close to the surface of the skin. Save
The smallest blood vessels are called capillaries. The next largest are veins. The largest are arteries. Arteries are deeper in the body than veins and capillaries, which are closer to the skin. Some veins are also deep within the body. There is no type of blood vessel starting with the letter "A" that is close to the skin.
