Immune System : Immune System Body’s defense network against infection Provides the body with resistance to invading organisms Enables the body to fight off invaders once they have gained access Antigens : Antigens Substances that stimulate a response form the immune system Antibodies Imunoglobulins: proteins that are created in response to specific antigens Immunity : Immunity Innate: present in the body at birth Acquired: develops after birth as a result of the body;s immune responses to antigens Depends on proper development of B & T Lymphocytes WBCs that fight infection 2 Ways Immunity Works : 2 Ways Immunity Works Antibody Mediated (humoral) Cell Mediated – function independently to provide the immune response Body Organs Vital to Immune System Function : Body Organs Vital to Immune System Function Thymus Bone marrow Lymph nodes Spleen Liver Immunodeficiency : Immunodeficiency High risk for infection Body’s inability to launch adequate immune response Disease processes Secondary to immunosuppressive medications Allergy : Allergy Atypical immune response Hypersensitivity In reaction to normally inoffensive foreign substance Anaphylaxis: crisis situation resultant from severe allergic reaction Autoimmunity : Autoimmunity Body’s inability to recognize self Abnormal immune system reaction Body destroys it’s own tissues You do not have the permission to view this presentation.
