Immunodeficiency Disorder

Immunodeficiency disorders prevent your body from fighting infections and diseases. This type of disorder makes it easier for you to catch viruses and bacterial infections. Immunodeficiency disorders are either congenital or acquired. A congenital, or primary, disorder is one you were born with. An acquired, or secondary, disorder is one you get later in life. Acquired disorders are more common than congenital disorders. Your immune system includes the following organs

• spleen
• tonsils
• bone marrow
• lymph nodes

These organs process and release lymphocytes. These are white blood cells classified as B cells and T cells. B and T cells fight invaders called antigens. B cells release antibodies specific to the disease your body detects. Certain T cells destroy foreign or atypical cells.
