ANATOMY

Detailed explanation-1: -On a basic level, autoimmune disease occurs because the body’s natural defenses-the immune system-attack the body’s own healthy tissue. Researchers have several ideas about why this happens. When the body senses danger from a virus or infection, the immune system kicks into gear and attacks it.

Detailed explanation-2: -An autoimmune disorder occurs when the body’s immune system attacks and destroys healthy body tissue by mistake. There are more than 80 types of autoimmune disorders.

Detailed explanation-3: -When you have an autoimmune disorder, your immune system does not distinguish between healthy tissue and potentially harmful antigens. As a result, the body sets off a reaction that destroys normal tissues. The exact cause of autoimmune disorders is unknown.
