Circulatory system. The human circulatory system (simplified). Red indicates oxygenated blood carried in arteries, blue indicates deoxygenated blood carried in veins. Capillaries, which join the arteries and veins, and the lymphatic vessels are not shown.
The deeper veins are usually blue/gray and are usually the cause of the smaller red/purple veins on your skin. The color of the vein does not matter. The only way to tell how severe your vein disease has become is to have an ultrasound performed.
