Quizplus · Accepted Answer

Rheumatoid arthritis is considered an autoimmune disease, in which the immune system attacks the joints, resulting in inflammation and destruction of the cartilage and bone within the joint. It can also affect other parts of the body besides joints, such as the lungs and blood vessels. RA has periods of remissions and exacerbations, and often affects joints bilaterally.
