Immune System InnativeAdaptive A) Skin and Mucosal membranes B) Secreted soluble proteins - Lysozyme -C-creative protein - Interferons - Complement system C) Cells - Macrophages - Mast cells - Natural Killer - Granulocytes A) Cells - B lymphocytes - T lymphocytes B) Antigen presenting cells C) Secrated chemicals - Antibodies - Complement - Cytokines

Components of the immune system A) Cells 1) T-cells - Helper T-cells - Cytotoxic T-cells - Supressor T-cells 2) B-cells 3) Natural killer cells 4) Polymorphonuclear Leukocytes 5) Macrophages 6) Dendritic cells - Basophil - Neutrophil - Eosinophil

B) Organs 1) Bone marrow 2) Thymus 3) Spleen 4) Lymph nodes

C) Antibodies -IgM - IgA - IgD - IgG D) Complement system E) Hormones

Immune response 1) Macrophage encounters a virus and consumes it 2) Macrophage digests the virus and displays pieces of the virus called antigens on its surface

3) Helper T cell recognizes the antigen displayed and binds to the macrophage. 4) This union stimulates the production of chemical substances

5) Killer T-cells multiply. B-cells multiply and produce antibodies 6) The killer T cells shoot holes in host cells

7) Antibodies bind to antigens on the surfaces of free-floating viruses 8) Activated T and B cells are turned off by suppressor T cells

Conditions associated with the immune system 1) AIDS Cause: -The Human Immunodeficiency Virus (HIV) causes AIDS -The virus attacks the immune system the body vulnerable to a variety of life-threatening illnesses and cancers. Treatment: -No cure for AIDS at present -Treatments that delay the progression of the disease: a) Antiviral agents b) Medication

2) Immune hemolytic anemia: Cause: - Premature destruction of red blood cells by the immune system Treatment: - Treatment with prednisone - Splenectomy - Immunosuppressive therapy

3) Idiopathic thrombocytopenic purpura: Cause: Treatment: - Platelets are being destroyed by the immune system -Oral danazol  -High-dose gamma globulin injections  -Drugs that suppress the immune system  -Passing the blood over a Protein A (Prosorba) column, which filters antibodies out of the blood stream  -Anti-RhD therapy can also be useful in people with specific blood types
