|
|
Term
| (type of white blood cell) What is a Monocyte? |
|
Definition
| Macrophages- ingest and kill microorganisms. They survive after ingestion and become Anitgen presenting cells! This means a portion of anitgen is expressed in the macrophages membrane and is recongized by lymphcytes. (memory cells!!) |

Definition
|
|
Term
| What are T cells reponsible for? |
|
Definition
| Cell mediated immunity! And have sufaces markers that are specific to an individual antigen |

|
Definition
|
|
Term
| What are B-cells responsible for? |
|
Definition
| Antibody production = Humoral Immunity |
|
|
Term
| What do B- cells produce? |
|
Definition
| Antibodies that are called plasma cells |
|
|
Term
| What happends after an immune response? (having to do with B-cells) |

|
|
Term
How the immune system destoys a virus..
|
|
Definition
1. White blood cells (macrophages) encounter a virus
2. Macrophage is a phagocytic cells and consumes the virus.
3. Other virus molecules infect nearby cells
4. The macrophages digest the virus and display the antigen on its surface
5. The nearby cells are now infected
6. T-helper cells revongnize the anitgen and binds to the macrophage
7.The binding of the T-helper simulates the production of a intercellular communication
8. The chemical produced then instructs other T-cellers and the Tcell killer to multiply
9.The more T-helper cells that release substances cause the B-cells to multiply and produce antibodies
10. The killer T-cells being shooting holes in the host cells that have the virus
11.The anitbodies realased by B-Cells bind to the antigens
12. Signals blood components, complements, to poke holes in virus.
13. As the infection is under control the activated T-B cells are turned off by suppressor T-Cells
14. Few memory cells stay behind incase the virus attacks again |
