Vein (French Pronunciation: [vɛn])325

Definition and Anatomy

A vein is a blood vessel that carries blood back to the heart. It is a thin, flexible tube that has valves to prevent blood from flowing backward. Veins are found throughout the body and are classified into two main types: superficial veins and deep veins.

Superficial veins are located just beneath the skin and are easily visible. They are often used for blood draws or intravenous injections. Deep veins are located deeper in the body and are surrounded by muscles or other tissues. They carry most of the blood back to the heart.

Function

Veins play a vital role in the circulatory system. They carry deoxygenated blood back to the heart, where it can be pumped out to the lungs to be oxygenated. Veins also help to regulate body temperature and fluid balance.

There are a number of common vein problems, including:
Varicose veins: These are enlarged, twisted veins that can be seen on the skin's surface.
Spider veins: These are small, red or blue veins that can be seen on the skin's surface.
