Definition
| innate (nonspecific) and adaptive |
|
|
Term
| How does innate immunity function |
|
Definition
| Functions the same each time |
|
|
Term
| First line of innate immunity |
|
Definition
| Physical barries (skin, mucuous membrane) and chemical barriers (digestive enzymes) |
|
|
Term
| 2nd line of innate immunity |
|
Definition
| Fever, Inflammation, chemotaxis, cytokines, phagocytosis, natural killer cells, interferons |
|
|
Term
| how many lines of innate immunity defense are there |
|
Definition
|
|
Term
|
Definition
| kills off pathogens that grow better at cooler temps |
|
|
Term
| What do Natural Killer Cells do? |
|
Definition
| They release perforins which target cancer and virus cells and cause them to lyse |
|
|
Term
|
Definition
| They stop viral replication and activate microphages and NK cells |
|
|
Term
|
Definition
| method by which leukocytes respond to damaged tissues |
|
|
Term
| How is chemotaxis achieved |
|
Definition
| by damaged tissues releasing cytokines which are chemical messengers |
|
|
Term
| What is the process by which WBCs squeeze through capillary slits in reponse cytokines |
|
Definition
|
|
Term
| what is the third line of defense |
|
Definition
|
|
Term
| What is in adaptive repsonses |
|
Definition
| anti-body mediated responses and cell mediated repsonses |
|
|
Term
| what is antibody mediated repsonse in response to |
|
Definition
| specific invading antigen |
|
|
Term
| Substance that stimulates adaptive immunity |
|
Definition
|
|
Term
| How does antibody mediated immunity work |
|
Definition
On the first exposure of the antigen to the B Cell, the B Cell divides and grows into plasma cells, which release antigens, and Memory B cells.
On the Second exposure, the memory B cells rapidly divide and produce antigens and a bigger response |
|
|
Term
| What type of immunity results from a vaccine being given to a person which exposes them to a pathogen and then the body produces antibodies for that pathogen |
|
Definition
|
|
Term
| What type of immunity results from antibodies being recieved from another source, not producin them themselves |
|
Definition
|
|
Term
| How does cell mediated immunity work |
|
Definition
| A macrophage captures the non-self cell. then a helper T cell release's cytokines, which causes cytotoxic T cells to destroy the nonself cell through chemotaxis |
|
|
Term
| When is cell mediated immunity used over antibody mediated immunity. |
|
Definition
| When the invader is inside the cell because antibodies cant cross the plasma membrane |
