Vasculitis is a general term for a group of uncommon diseases that feature inflammation of the blood vessels. The blood vessels of the body are referred to as the vascular system. The blood vessels are composed of arteries, which pass oxygen-rich blood to the tissues of the body, and veins, which return oxygen-depleted blood from the tissues to the lungs for oxygen. Vasculitis is characterized by inflammation in and damage to the walls of the various blood vessels.
