Document Summary
Function of immunology system: re(cid:272)og(cid:374)ize (cid:862)(cid:374)o(cid:374)self(cid:863) fro(cid:373) (cid:862)self(cid:863, eliminate foreign substances (antigens) as efficiently as possible, produce antibodies. Granulocytes: nuclear bodies within them, neutrophil (54-62%, phagocytosis cell defends against bacteria. Increased in bacterial infections, inflammatory process, some malignancies: eosinophil (1-3%, associated with antigen-antibody reactions. Increased in allergic reaction, decreased in children receiving corticosteroids: basophil (0-3%, phagocytic cell, involved in immediate hypersensitivity reaction, stores histamine and has receptor sites for ige. Increased in leukemia, decreased in allergy, acute infection, collagen, chronic diseases. Agranulocytes: no nuclear bodies within them, lymphocyte (t, b, non b/non t (nk)) (25-33%, major components of immune system. Immunoglobulins = sub function: many roles in a number of immunologic reactions, decreased in child with immune deficiency. Increased in presence of infection or allergic response: make antibodies. Increased in many infections, decreased in child with immune deficiency: monocyte (4-9%, phagocytic cell active in chronic infections, live in lymph system, long life.
