immune system

2. arms produced by the phagocyte that wrap around the pathogen when it is detected
9. one way foreign cells end up in our bodies, altered DNA means different antigens
10. the process where white blood cells destroy foreign cells
11. the arms fuse together engulfing the pathogen leaving it enclosed in a vesicle
15. small white blood cells
17. white blood cells with a large nucleus that carry specific receptors
18. one way foreign cells end up in our bodies, organisms that cause disease(bacteria,viruses)
19. large white blood cells

1. one way along with using similar cells( relatives) that can reduce immune response when you have a transplant- however it can make the immune system less effective against other infections
3. what happens to cells that are recognised as foreign by the immune system?
4. one way foreign cells end up in our bodies, organisms of the same species, antigens from transplant seen as foreign
5. cell surface antigens, identify the cell as self
6. humoral response
7. cellular response, defence mechanism
8. substance that causes immune response
12. what the lysosome releases after it has bound to the phagosome
13. immune response involving lymphocytes
14. the hydrolytic enzymes destroy bacteria cell walls to destroy the pathogen
16. one way foreign cells end up in our bodies, poison produced by pathogenic bacteria can damage cells and metabolic processes which causes an immune response
