Across
  1. 1. White blood cell that engulfs and digests pathogens (phagocytosis).
  2. 5. Antibodies clumping pathogens together for easier phagocytosis.
  3. 7. Antibodies produced from a single clone of B-cells, identical in structure.
  4. 9. Type of immunity where antibodies are acquired from another source (e.g., mother to baby, monoclonal antibodies).
  5. 10. Type of immunity where the body produces its own antibodies (natural exposure or vaccination).
  6. 12. Long-lived cells (B or T) that remain after infection for a rapid secondary response.
  7. 13. Mature in the thymus; involved in cellular response (killing infected cells, activating B-cells).
Down
  1. 2. Y-shaped glycoprotein (immunoglobin) produced by B-cells that binds to specific antigens.
  2. 3. Microorganism that causes disease.
  3. 4. Introduction of antigens to stimulate an immune response and create memory cells.
  4. 5. Specific protein/molecule on a cell surface triggering an immune response.
  5. 6. Mature in bone marrow; produce antibodies (humoral response).
  6. 8. White blood cells involved in specific immunity (T-cells and B-cells).
  7. 11. Cloned B-cells that produce antibodies.
