Blood & immune system
Blood carries oxygen and nutrients, and white blood cells defend you from infection. In autoimmune disease, that defense system targets your own tissues.
Reproductive organs
Your ovaries and uterus shape your cycle, fertility, and hormones. Sex hormones also influence the immune system, one reason autoimmune disease is more common in women.
Brain & nerves
Your brain, spinal cord, and nerves carry every signal in your body, from movement and sensation to mood and memory.
