Across
- 5. associated with B-cells, uses B-cells to bind to antigen
- 8. obtained from antibodies actively produced by another organism
- 10. associated with T-cells, mostly dendritic and microphage cells
- 11. originated in the thymus, attack infected body cells
- 15. a last effort from a cell to warn other cells
- 16. the process of "eating" to break down microbes
- 18. the first exposure to an antigen, takes 3-14 days to appear
- 19. also knows as innate immunity, an immediate response
Down
- 1. a quicker response to antigens after the first interaction
- 2. the study of internal defense systems of humans and other animals
- 3. phagocytes that develop from monocytes, later to arrive but stays until the end
- 4. reaction against the own body's cells
- 6. hypersensitivity results in the manufacture of antibodies against mild antigens
- 7. uses perforins to make pores in target cell membranes
- 9. common in white blood cells, arrive quickly but tend to loose interest
- 12. include long cytoplasmic extensions, developed in bone marrow
- 13. also known as acquired immunity, a specific response
- 14. T-cells ability to use specific T-receptors after a period of time
- 17. originated in bone marrow, mature into plasma cells and produce antibodies
- 20. a chemical used to transport information and act as an energizer
