    T cell (T lymphocyte)
  36. The ability of T lymphocytes to recognize and accept the body's own antigens as "self" or friendly. Once tolerance is established, the immune system will not react against the body.

  39. Mass of lymphatic tissue in the back of the oropharynx.
  40. Poison; a protein produced by certain bacteria, animals, or plants
  41. Exposure of an individual to a foreign protein (antigen) that provokes an immune response. The response will destroy anyt cell that possesses the antigen on its surface and will protect against infection.
  42. Weakened or killed microorganisms, toxins, or other proteins given to induce immunity to infection or disease.
