What are auto-immune disorders ? Give any two examples.

Explanation

Generally our immune system can recognize our own proteins (self antigens) and does not attack our own tissues. Unfortunately, in some cases our immune system fails to recognise some of our own body proteins and treats them as foreign antigens, that results in attacks on our own tissues. This leads to some very serious diseases collectively known as autoimmune disease,
Eg: 1. Graves. disease 2. Rheumatoid arthritis.
