What is a superficial vein?

When a person looks at the body, he notices blue lines that seem to be directly under the skin. Sometimes some of these protrude, especially if the person is warm. These are superficial veins.

veins are basically part of the blood transport network. While arteries send blood from the heart to oxygenation of organs and tissues, the veins work to return this blood to the heart so that it can be sent back to the lungs to pick up more oxygen. The term superficial vein is a term used as opposed to a deep vein. The deep veins are close to the artery with a name that is similar and usually cannot be seen on the body surface. They are also often larger than superficial veins and more important.

The superficial vein is not located near the arteries with similar names, and although they are important to the body, they are not as important as deep veins. In fact, if such a vein becomes too prominent or varicase becomes, a term usually reserved for veins in the feet, people may have a surgery called Stripping vein. ProtrudingOje these veins are superficial, it is usually safe, because blood flow to the legs will still be sufficient through deep veins. One of the largest differences between Hluboka and Sunday vein is the amount of blood transported; Deep veins are responsible for transporting most blood and superficial veins, although important, are much less.

There are several of these veins that people can be known with. The jugular vein, which actually carries a large volume of blood, runs down the neck on both sides and returns blood from the head to the heart. When people have blood tests, they often have blood taken from the surface vein on both arms called the middle cubes, which may or may not be apparent on the underside of the arm, opposite the elbow.

Many people wonder why it seems that veins, or takmetimes stand out in hot weather after exertion. This is actually the function of these smaller blood vessels. If the body is heated, deep veinsThey send more blood to surface veins as a temperature control method.

Some conditions may affect the superficial vein. Like deep veins, these close to superficial veins can also obtain blood clots called superficial thrombophlebitis. It can be painful, but usually does not endanger life. The condition can cause inflammation of the vein that can be felt, often as a hard impact under the skin, and may require some special treatment with pain relief and compression stockings (as usually occurs in the leg). The superficial thrombophlebitis is generally solved in a few weeks, but doctors may want to check the risk factors for the development of deep venous thrombosis (DVT), which is much more serious.
