    primary defense against invading pathogenic organisms
  23. What are the functions of lymphocytes?
    • important in antibody production
    • communicating with other cells in immune system 
    • production of cytokines.
  24. conditions that affect WBC percentage?
    • Bacterial infection
    • Viral infection
    • infectious mononucleosis 
    • parasitic infection
    • allergic reactions
    • Leukemias
  25. Increased total WBCs, increased percentage of neutrophils andbands
    Bacterial infection
  26. Decreased WBCs, increased percentage of lymphocytes
    Viral infection
  27. Increased total WBCs,
    increased lymphocytes,
