Unit 1 Flashcards
immunity and immunology
free of burden and study of host defense
innate (natural)
control boat, always present
present prior to exposure
nonspecific
phagocytic cells (eat foreign things)
acquired (adaptive)
memory and specificity
cells produce specific response to antigen
gets faster and stronger after exposure (booster)
humoral (body fluids)
send out antibodies
specifically recognize and remove antigen
antibodies not present until antigen
B- lymphocytes
cell-mediated
send out cells to handle business
t-lymphocytes (has 1 specific antigen)
destroys intracellular (viruses, bateria, fungi
5 features of immune response
specificity (adaptive immunity)
immunologic memory
diversity
self regulation
self vs non self
specificity
immune response toward distinct antigens
immunologic memory
response faster and stronger after each exposure
diversity
can recognize a billion antigens
self-regulation
want response to raise with exposure but drop off when done
self vs non-self
response against foreign antigens not self antigens
macrophages
phagocytes = defense after skin, cells that eat
granulocytes
neutrophils, basophils, eosinophils
neutrophils
only phagocyte
1st to inflammation
basophils
allergies and anaphalyaxis
