Immune System

Module Nine Lesson One Assignment Two By: Brielle Winner

Autoimmune Disease

What is it?

This is when the body attacks and destroys healthy body tissue. It can cause destruction of one type of body tissue, abnormal organ growth, and changes in function of organs. It affects blood vessels, connective tissues, endocrine glands, joints, muscles, red blood cells, and skin.


Some examples are addison's disease, celiac disease, dermatomyositis, graves disease, hoshimotos disease, multiple sclerosis, myasthenia gravis, pernicious anemia, reactive arthritis, rheumatoid arthritis, sjogren syndrome, systemic lupus, and type 1 diabetes.


What is it?

This is when the body cannot fight disease and infection the way that it should. They can be congenital where you are born with it or acquired where you obtain it after birth. People with this disorder will get sick more often than healthy, normal people would. Some risk factors can be if you have a family history of immunodeficiency disorders, exposure through bodily fluids, removing the spleen, insufficient proteins in the body, and cancer treatments.


Some congenital examples would be hypoglammaglobulinemia, agammaglobulinemia, SCID disorders. Acquired examples are HIV/AIDS, Cancers of the immune system (Leukemia), immune complex disease (viral hepatitis), and multiple myeloma (cancer of plasma cells).

Whats the difference?

A major difference is that an autoimmune disease is when your body attacks itself because it thinks it is a disease or is harmful so it tries to fight it. Immunodeficiency is not being able to fight against disease that may come from outside the body.
