What types of veins are there?
There are three major categories of veins: superficial veins, deep veins, and perforating veins. All varicose veins are superficial veins; they lie between the skin and a layer of fibrous connective tissue called fascia.
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.

Three types of veins are?
The three main types of veins are superficial veins, deep veins, and perforating veins. Superficial veins are located just beneath the skin and are often visible, while deep veins are located deeper within the body, typically accompanying arteries. Perforating veins connect superficial veins to deep veins, allowing for blood flow regulation between the two systems. Each type plays a crucial role in returning deoxygenated blood to the heart.
What are the little veins called that are close to the skin that start with an A?
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.
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").
