| Two divisions of Immunity: |
|
Definition
|
|
Term
|
Definition
Natural/ “non-adaptive” / “first line defence”
“Always the same” |
|
|
Term
| Acquired/Adaptive Immunity |
|
Definition
First exposure- “slow” rxn
“Memory” results in improvement upon subsequent exposures. |
|
|
Term
|
Definition
| Acquired immunity- Get sick enough to get adaptive response kick in but not the innate response. |
|
|
Term
| Interaction between the two types of immunity: |
|
Definition
innate and adaptive systems POSTIVE intrxns
They have to interact with each other- exist together. |
|
|
Term
|
Definition
immediate
Initially present
May appear shortly (hours) after |
|
|
Term
| Innate immunity recognizes: |
|
Definition
“danger”
Much more general compared to adaptive |
|
|
Term
| innate immunity after response- |
|
Definition
|
|
Term
| Does innate immunity ever improve? |
|
Definition
|
|
Term
| Innate immunity barriers: |
|
Definition
| some physical and some chemicals |
|
|
Term
|
Definition
| Short term response- slow; improves the next time to much faster |
|
|
Term
| Acquired immunity memory speed: |
|
Definition
| Takes 1-2 weeks to build up to a memory response |
|
|
Term
| Acquired immunity recognizes: |
|
Definition
| Recognize “antigens”- recognized by antibody |
|
|
Term
| Acquired immunity barriers: |
|
Definition
| antibodies, Memory B cells, WBC |
|
|
Term
Lymphatic system runs -- with --
removes-- from --
uses -- cells |
|
Definition
parallel with blood vessels
removes wastes from tissues
WBC |
|
|
Term
| Lyphatic system uses a White blood cells, esp: --. |
|
Definition
| lymphocytes primarily adaptive IS |
|
|
Term
| What is critical for WBC to mature? |
|
Definition
|
|
Term
|
Definition
Travel through
Monitor waste for infection
Lymph nodes = filters +meeting places (cell to cell intrxns)
filter antigen |
|
|
Term
Where do Cells of the Immune System come from?
Where do the differentiate? |
|
Definition
Come from hematopoietic (blood) stem cells
Differentiate in bone marrow and thymus |
|
|
Term
| most IS cells are innate and come from --. The bridge between innate and adaptive it: |
|
Definition
| innate Myeloid stem cell . natural killer cell bridge |
|
|
Term
| adaptive IS cells come from -- |
