Lymphocytes types-
purpose-
|
-B cells and T cells
-immune response to specific pathogens in humoral immunization
|
|
| 7 |
B cells maturation-
purpose-
|
-mature in bone marrow
-have receptors to antigen epitopes. when specific antigen is found...
|
|
| 8 |
antigens purpose-
|
-antigens are chemical molecules that bind to lymphocytes B and lead to an immune response
|
|
| 9 |
antibodies types-
purpose-
|
-IgM, IgG, IgA, IgE IgD
when binded by antigen they activate immune responses
|
|
| 10 |
immune responses activated by antibodies-
|
-complement, inflammation, neutralization, opsonization, direct killing, agglutination, cytotoxicity
|
|
| 11 |
complement cascade starts how-
process-
antibodies-
outcomes-
|
-from opsonization and inflammation as well as ag and ab binding
-protein in serum comes together...
|
|
| 12 |
inflammation starts-
process-
outocmes-
|
damaged tissues and release of histamines
-dilate blood vessels to increase blood flow and...
|
|
| 13 |
phagocytosis starts how-process-outcome-
|
-from chemotaxis by organisms in inflammation-phagocytotic cells surround pathogens and microbes-kill...
|
|
| 14 |
humoral immunity consists of-most effective against-starts how-process-antibodies-outcomes-
|
-B cells creating antibodies-useful against virus, bacterias, and toxins-apc antigen processing...
|
|
| 15 |
cell mediated immunity best for-consists of-process-outcome-
|
-best for fighting worms cancer, fungi-starts from exposure of antigenantigen processing cells...
|
|
| 16 |
immediate hypersensitivity starts from-1st reaction known as-2nd reaction effects and process-antibodies-outcome-
|
-exposure to allergen antigens-sensitization. as IgE binds to masat cells baso and eosino-allergen...
|
|
| 17 |
cytotoxic hypersensitivity from-process-antibodies-outcome-
|
-blood type error-body releases anti opposite of given antibody which activates complement -Igm...
|
|
| 18 |
autoimmune disease cause-process-antibody-outcome-
|
-exposure to foreign antigen similar to our own-results in antibodys being created against...
|
|
| 19 |
Functions of antibodies IgM-IgG-igaigeigd-
|
-most efficient for complement and inflammation-most common one. can leave blood vessels. help...
|
|
| 20 |
opsonization-
|
-changing antigen surface to increase phagocytosis
|
|
| 21 |
agglutination-
|
-causes clumping of antigens and makes the precipitate, increases chance to be phagocytized...
|
|
| 22 |
test for allergic reaction-
|
-test for IgE
|
|
| 23 |
tcells types-
|
-helper t cells-regulatory t cells
|
|
| 24 |
helper t cells purpose-secrete-what disease renders them ineffective-
|
-regulate entire immune system-secrete cytokines (messengers) that tell body immune what is...
|
|
| 25 |
regulatory t cells purpose-
|
-suppressimmune system to prevent autoimmune disease
