Term
| Foreign host that enter the body are reconized by? |
|
Definition
- neutrophils
- lymphocytes
- macrophages
|
|
|
Term
| This type of immunity is present at birth. It attacks non-self pathogens, does not distinguish among different types. |
|
Definition
|
|
Term
| What are the cells of innate immunity? |
|
Definition
- Neutrophils
- Macrophages
- Dendrite
- Natural killer
|
|
|
Term
| These are first responders, phagocytic, release proteases, cytokins(messenfers that coordinate immune and inflammatory responce) |
|
Definition
|
|
Term
| These are phagocytic, Active adaptive immunity, becomes antigen presenting cell, enhances inflammation, active in healing. |
|
Definition
|
|
Term
| APC engulf invader to show to lyphocyte |
|
Definition
|
|
Term
| Undifferentiated lymphocytes, automatically kill foreign cells |
|
Definition
|
|
Term
| Series of 20 plasma protiens that promote and enhance immune/immplammatory functions- Activated by antigen or metabolic function of bacteria |
|
Definition
|
|
Term
|
Definition
- Opsonization- coats bacteria to mark as invader
- Chemotaxis- cytokines to attract immune/ inflammatory cells
- Cell membrane attack complex- final event in complement
|
|
|
Term
| Specific cell attacks specific antigen, devolopes after exsposure to the antigen. |
|
Definition
|
|
Term
| Antibody protien in the blood that attacks the specific antigen |
|
Definition
|
|
Term
| Phagocytic cells attack the specific antigen, T lymphocytes |
|
Definition
|
|
Term
| How do lymphocytes develope |
|
Definition
| Stem cells start, B cells mature in bone marrow, T cells mature in thymus, they then move to the lymph nodes to wait for an antigen presenting. |
|
|
Term
| The master regulator of the immune system |
|
Definition
|
|
Term
| Killer cells, they are taught what specific cells to kill. |
|
Definition
|
|
Term
| What tells the immune system what to attack |
|
Definition
|
|
Term
| This is activated by CD4 to kill invaders? |
|
Definition
|
|
Term
| What happens after B cells are activated? |
|
Definition
| They become plasma cells and release antibodies |
|
|
Term
| This creates antibodies that attach to an antigen to mark and destroy is. |
|
Definition
|
|
Term
| Why are antibodies created? |
|
Definition
| They are created to match the idenity characteristics on the antigen cell. |
|
|
Term
| What happens during primary immune responce |
|
Definition
- Macrophages engulf antigen-present to cd-4
- cd-4 activates b cells
- B cells produce antibodies
- Plasma antibody levels rise
- Vaccination produces primary immune response
|
|
|
Term
| What happens druing secondary immune response |
|
Definition
- B memory respnd to antigen immediatley( no Cd-4 effect)
- Plasma antibodies rise within a day
- Booster shot
|
|
|
Term
| All together how does body react to invaders? |
|
Definition
- Antigen enters body
- phagocytes engulf
- Shows to CD4
- CD4 activates CD8
- Activates B cell
- Plasma cell/ memory cell make antibody
