primary immunity AKA natural
innate
secondary immunity AKA adaptive
acquired
immediate, nonspecific line of natural immunity
defense that's present at birth; does
not alter on repeated exposure to
any specific antigen
specific immunity, acquired by adaptive immunity
contact with specific foreign
substance
two categories of innate immunity physical barriers
biochemical barriers
physical innate immunity barriers intact skin
include mucous membranes
cilia
cough reflexes
, biochemical innate immunity barriers bacterial enzymes
include fatty acids
sweat
digestive salivary enzymes
stomach acid
low pH
cells of the ________ system do not innate immune
need prior exposure to work. they
just recognize and work to neutralize
non-self threats
three major components of innate phagocytic leukocytes
immune system natural killer
complement system
two major phagocytic cell types polymorphonuclear (granulocytes)
mononuclear (monocytes/microphages)
polymorphonuclear cells are granulocytes (eosinophils, neutrophils, basophils)
phagocyte found in circulation monocyte
phagocyte found in tissue macrophage
complement system's three major final lysis of pathogenic and abnormal cells
roles in immunity opsonization and phagocytosis
the specific, most highly evolved, adaptive (acquired) immunity
major arm of the immune system that
allows immune system to remember
(memory) pathogens previously
encountered
