blood vessels which carry blood back to the heart from body regions.

To understand vein disease, which is the primary cause of varicose veins, it's first important to understand the venous system of the human body. The venous system is the part of the circulatory system that returns deoxygenated blood through veins back to the heart to be recirculated. By contrast, the arterial system carries oxygenated blood away from the heart to be distributed throughout the body. The smallest parts of the venous system are the capillaries, which feed into larger superficial veins.
