What are normal veins?
Veins are a type of blood vessel that brings blood back from the tissues of the body to the heart. The veins in your legs, therefore, carry blood up the legs towards the heart. There are two main types of veins: • Superficial veins are those that you can see or feel (if your skin is dark) just under the skin. They are more prominent when they are under pressure, which is why an armband helps doctors find the veins in your arm before they give injections or take a blood sample. The veins in your legs are also more prominent when you stand up, because they have to work harder to return blood against gravity. • Deep veins are further from the skin surface. In the legs, they are within the muscle of the leg and can not be seen.
