Raynaud's phenomenon

Raynaud's phenomenon is characterized by blood vessel spasms in the fingers, toes, ears or nose, usually brought on by exposure to cold. Raynaud's phenomenon and Raynaud's disease, a similar disorder, may be associated with autoimmune disorders such as rheumatoid arthritis, systemic lupus erythematosus and scleroderma.

Systemic lupus erythematosus

Systemic lupus erythematosus is a chronic inflammatory autoimmune disorder which may affect many organ systems including the skin, joints and internal organs. The disease may be mild or severe and life-threatening. African-Americans and Asians are disproportionately affected.

Circulatory system

Blood used by the body is brought back to the heart and lungs by the veins of the body. Once the blood has gathered more oxygen from the lungs, it is pumped back out to the body through the arteries.
