    Able to recognize and respond to an antigen
    20-25% of WBCs
    3 types
    Lymphocytes
  26. Matures and resides in lymphoid tissue
    Plasma cells and B memory cells
    B Lymphocytes
  27. Produce proteins called antibodies (aka immunoglobulins) that are carried in blood serum
    Plasma Cells
  28. Antibody combined with an antigen
    Immune complex
  29. Travel to thymus to mature
    Many different functions
    T Lymphocytes
  30. Involves the production of antibodies
    B lymphocytes are primary cells
    Humoral Response
  31. Involves lymphocytes working alone or assisted by macrophages
    Cell-mediated Response
  32. Plasma cells produce IgE as a response to the antigen
    Reaction occurs within minutes after exposure to previously encountered antigen
    Anaphaylaxis
    Type I Hypersensitivity
  33. Compliment components participate in this type of reaction
    Rhesus incompatibility
    Type II Hypersensitivity
  34. Type of reaction in autoimmune diseases
    Type III Hypersensitivity
