The Immune System

5. Stimulates an immune response
6. Cell division resulting in more cells and differentiation into plasma cells or memory B cells
7. respond to chemicals released by pathogens and cells during infection
9. also called immunoglobulins
11. attenuated virus/bacteria that trigger an immune response and memory cells
13. these cells secrete antibodies that bind to antigens, making them easier targets for phagocytes
14. play an important role in the adaptive immune system
16. bind to receptors on T-cells stimulating rapid mitosis
17. These blood cells are also known as lymphocytes

1. these fragments of the virus interact with aclass 1 MHC
2. Trigger programmed cell death
3. these types of cells respond rapidly to a second exposure of antigens resulting in plasma cells and cytotoxic t cells
4. ------- are the same in all of the antibodies
8. The immune system that has two types of specific responses called cell-mediated and antibody mediated
10. these cells are specific to a particular antigen
12. engulphs the pathogen
15. assists the T-cell receptor
16. T.Cells Are activated by cells infiected with a pathogen
