Your Veins

YOUR BODY'S HIGHWAYS

Our blood is carried in our body by two types of blood vessels. The arteries and the veins. The arteries carry nutrients and oxygen to our body's organs and tissues.


Our veins serve to return the blood from the body's tissues and organs back to the heart. Our blood flows one way up against gravity in large part thanks to a series of pockets located inside our veins. These pockets are called venous valves.


When the valves become damaged, blood can run backwards and pool in the vein. This results in increased pressure inside the veins, which is the cause for veins we see through the skin. These changes in the smallest veins are known as spider veins. If the damaged veins are large and "ropey," they are known as varicose veins.
