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.

Digestive tract
Your stomach and intestines absorb nutrients and hold most of your body's immune tissue, which makes the gut a common target in autoimmune disease.
