In autoimmune illnesses such as rheumatoid arthritis, the body's which system is involved?

• A. Lymphatic
• B. Circulatory
• C. Immune
• D. Endocrine

Answer: (C)

Autoimmune illnesses occur when the immune system malfunctions and starts attacking the body's own tissues. In rheumatoid arthritis, immune cells and antibodies specifically target the joints, causing inflammation, pain, and potential joint damage. That makes the immune system the correct system involved. The lymphatic system supports immune function but the core idea is that the immune system itself is at fault. The circulatory system moves blood, and the endocrine system controls hormones; neither is the primary driver of the autoimmune attack seen in RA.
