Veins as part of the circulatory system, are blood vessels that carry deoxygenated or oxygen poor blood away form the vital organs of the body and transport these blood to the heart so that the heart can pump it back to the walls of our lungs, the alveoli, where the blood picks up oxygen. The rest of the process continues where the oxygenated blood is distributed back to the vital organs via another major blood vessel, the artery.
The subject of our discussion are veins. Now why veins? Veins play a vital role for our existence but then, there are some veins that, aside from being in fact are almost useless, has become a bother and an can cause an ugly sight to an otherwise flawless skin. These are called spider veins. This has become a big concern for the people who are affected.
But let us be fair to the viens. Let us have closer understanding of the diferent types.
Ø Deep Veins. These type of veins are are found deep in the leg between muscle bundles and fascia, a tough fibrous tissue covering the bundles of muscles. Very functional, they are responsible for returning 90-95% of the venous blood back to the heart.
Ø Perforating Veins. These veins are smaller in size, actually intermediate in size, to the deep veins and they link the deep and superficial veins together.
Ø Superficial Veins. As minute as it seems, it has brought a big worry to some people. As superficial as they are, this very nature they have is what gave them a profound effect to those who are concerned about the appearance of their skin. These veins are usually affected by varicosities because they have little external support like the deep veins. These veins are visible from the skin when they varicose or swell with blood. They drain the blood from the skin and are also responsible for blood storage. When these veins become varicose they can appear engorged and distended. This group also includes reticular veins and “spider” veins. Reticular veins are small blue veins often seen through the skin. These are often the cause of spider veins, which are the tiniest blue purple veins seen in the skin.
