Immune Quiz Flashcards
What factors weaken the immune system
stress, diet, alcohol, loneliness, nicotine, UV radiation
which WBC’s are capable of phagocytosis
monocytes & neutrophils
what are the parts of the lymph system
lymph capillaries, lymph nodes, spleen
what are the functions of the spleen
store RBC, destroy RBC & platelets, help fight infection
what are the main concerns if the spleen is removed
immunosuppression - infection
Macrophage to Helper T (Cell mediated)
decides whether antigen is good or bad (gateway to immune memory response)
Cytotoxic T (killer)
seek, destroy, fight foreign cells (virus, cancer, bacteria)
Memory T
keeps in memory which cells to kill next time
Suppressor T
stops immmune response (tells killer cells to stop fighting so they don’t kill the good cells also)
Macrophage to helper T (humoral)
can’t decide whether the antigen is good or bad - sends to B cell
B cell
decides whether antigen is good or bad
Memory B
keeps in memory which cells to kill next time - make more antibodies
Plasma cell
makes antibodies that wrap around bad cells
suppressor B
stops the antibodies
the main difference between humoral and cell mediated
humoral uses antibodies
what is artificially acquired passive immunity
artificially made antibodies given to someone with rabies
naturally acquired passive immunity
mom gives baby antibodies through breast milk
artificially acquired active immunity
get vaccines - exposed to antigen
naturally acquired active immunity
makes own antibodies
what is an injectable form of antibodies given to a person exposed to a disease
vaccine
the clumping action of antibodies is called
agglutination
what are colony stimulating factors
prompt bone marrow to produce needed blood cells
which colony stimulating factor increases RBC production
Epoeitin Alpha (Epogen, Procrit)
which increases WBC production
filgrastin (neupogen)
why are transplant patients more susceptible to infection
they are on immuno-suppressants so the organ doesn’t get rejected - so their immune system is weakened
what is the name of the chemical messengers released by WBC’s
cytokines
which one helps cells suppress viruses
interferons
why can’t interferons be given PO
body (stomach acid) will destroy it
