Rheumatoid Arthritis

Rheumatoid arthritis is a chronic, systemic inflammatory disorder that may affect many tissues and organs, but principally attacks flexible (synovial) joints. The process produces an inflammatory response of the capsule around the joints (synovium) secondary to swelling of synovial cells, excess synovial fluid, and the development of fibrous tissue in the synovium. The pathology of the disease process often leads to the destruction of articular cartilage and ankylosis of the joints. (adapted from wikipedia)
