Arteries carry blood away from the heart while veins carry blood to the heart.
Veins have a series of valves that allow blood to be carried against gravity and prevent a back flow of blood.
Varicose veins are abnormally dilated veins, which may twist and turn.
It is caused by valves in the veins that stretch and weaken, causing blood to pool in the lower extremities.
Varicose veins can occur in legs, esophagus (food tube), or rectal area.
