AP PSYCHOLOGY

Detailed explanation-1: -When the body senses danger from a virus or infection, the immune system kicks into gear and attacks it. This is called an immune response. Sometimes, healthy cells and tissues are caught up in this response, resulting in autoimmune disease.

Detailed explanation-2: -What if Your Immune System is Too Strong? There are some conditions where an immune system can get too strong. For example, allergies, asthma or eczema can occur if an immune system is too strong. Autoimmune disease is also thought to happen due to an overactive immune system.

Detailed explanation-3: -An autoimmune disease is the result of the immune system accidentally attacking your body instead of protecting it. It’s unclear why your immune system does this. There are over 100 known autoimmune diseases. Common ones include lupus, rheumatoid arthritis, Crohn’s disease and ulcerative colitis.

Detailed explanation-4: -Autoimmune disease happens when the body’s natural defense system can’t tell the difference between your own cells and foreign cells, causing the body to mistakenly attack normal cells.

Detailed explanation-5: -The immune system produces antibodies against these antigens that enable it to destroy these harmful substances. 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.
