Overview of Immunity Flashcards
(19 cards)
the state of protection from infectious disease involving specific and non-specific elements
immunity
employs components of the immune response that specifically recognize and selectively eliminate micro organisms and molecules perceived as foreign by the host
specific immunity (aka acquired)
utilizes the basic resistance to disease that a species possesses and makes up the first line of defense
nonspecific immunity (aka innate)
anything that the adaptive immune response can recognize (antibody generating)
antigen
viruses, some bacteria and parasites = _____ pathogens
intracellular pathogens
most bacteria, fungi, and parasites = _____ pathogens
extracellular pathogens
immune systems 1st line of defense
innate (non-specific)
immune systems 2nd line of defense
adaptive (specific)
white blood cells are considered
leukocytes
this immunity involves mainly granulocytes
innate immunity
this immunity involves lymphocytes (longest lived cells) mainly
acquired immunity
neutrophils, basophils, and eosinophils are considered ____ and are involved in which immunity
granulocytes - innate immunity
macrophages, kupffer cells, and dendritic cells are considered ____ and are involved in which immunity
monocytic - innate immunity
helper cells, suppressor cells, and cytotoxic cells are considered ____ and are involved in which immunity
t cells - acquired immunity
plasma cells are considered _____ and are part of which immunity
B cells - acquired immunity
____ response is the same to repeated exposures of the same pathogen
innate
____ response matures over time, repeated exposure leads to faster response
adaptive
- lag period
- antigen specific
- development of memory
adaptive immunity
- no time lag
- not antigen specific
- no memory
innate immunity
