IMMUNITY
CONCEPT OF IMMUNITY
USES LEUCOCYTES
GRANULOCYTES
NEUTROPHILS
PHAGOCYTES
EOSINOPHILS
ALLERGY REACTIONS
BASOPHILS
SECRETES HISTAMINE & HEPARIN (ANTI-COAGULANT)
AGRANULOCYTES
MONOCYTES
FORMS MACROPHAGE TO ENGULF ANTIGENS
LYMPHOCYTES
IMMUNE RESPONSE
LYMPHOID TISSUES & ORGANS
BONE MARROW
PRODUCES RBC, WBC & PLATELETS
THYMUS
ORGAN IN THE NECK
NECESSARY FOR DEVELOPMENT OF LONG-LIVED LYMPHOCYTES & T-LYMPHOCYTES
PRIMARY LYMPHOID ORGAN, AS IT PRODUCES LYMPHOCYTES FOR OTHER LYMPHOID TISSUES
SPLEEN
PHAGOCYTOSIS OF RBC & CELL DEBRIS
ABLE TO CONTRACT & EXPEL CONTAINED BLOOD TO MEET AN INCREASE IN CIRCULATORY DEMANDS
PROVIDES LYMPHOCYTES & A SOURCE OF PLASMA CELLS, HENCE ANTIBODIES
TONSILS
HELPS FIGHT OFF PHARYNGEAL & UPPER RESPIRATORY TRACT INFECTIONS
LYMPH NODES
LYMPH FLOWS THROUGH, B & T LYMPHOCYTES & MACROPHAGES REMOVE PARTICULATE DEBRIS, MICROBES & TOXINS & RELEASE ANTIBODIES
WILL BE ACTIVATED & MULTIPLY IF THERE IS INFECTION, CAUSING THE LYMPH NODES TO SWELL
HUMAN DEFENSE MECHANISM
ANTIGENS (IMMUNOGEN)
PROTEIN / GLYCOPROTEIN PRESENT ON SURFACE OF PLASMA MEMBRANE OF INVADING ORGANISM / SUBSTANCE
ANTIBODIES (IMMUNOGLOBULIN)
PROTEIN MOLECULES SYNTHESIZED BY BODY IN RESPONSE TO FOREIGN ANTIGENS
CLASSES
AGGLUTININS
CAUSES FOREIGN PARTICLES TO STICK TOGETHER IN CLUMPS
MAKES ANTIGENS MORE VULNERABLE TO ANTIBODY / MACROPHAGE
PRECIPITINS
CAUSES PRECIPITATION ON ANTIGEN-ANTIBODY COMPLEX
ANTITOXINS
NEUTRALIZES TOXINS PRODUCED BY MICROORGANISMS SO IT DOESN'T GIVE EFFECT
LYSINS
BREAKS DOWN FOREIGN MATERIALS, DISINTEGRATING IT
OPSONINS
STIMULATES MACROPHAGE TO ENGULF FOREIGN PARTICLES THAT POSSESS THE RIGHT ANTIGEN
