2nd line of defense (inflammatory response) Flashcards
causes of 2nd line defense
infection, mechanical damage, radiation, ischemia
purpose of 2nd line defense
prevent infection of injured tissue
when does inflammatory response occur
PAMPS or tissue damage
describe inflammatory reponse
nonspecific, rapid, no memory cells
vascular response
vasodilation; capillary permeability/leakage; WBC
once infection in tissue what does inflammatory response do
Limit and control the inflammatory process
Prevent and limit infection and further damage
Interact with components of the adaptive immune system
Prepare the area of injury for healing
systems involved in inflammatory response
complement — antigen/antibody
clotting-fibrin mesh at site
kinin ( activate inflammatory cells)
neutrophils
bacteria
eosphils
parasites
basophils
allergies/asthma
recognize & eliminate cells infected
w/viruses & cancer cells
NK cells
main component of adaptive immune response
lymphocytes
stops bleeding & degranulation
platelets
produced in bone marrow, migrate to inflammatory site
& develop into macrophages (important initiators of inflammation,
helps in wound healing, predominate in late inflammation
monocytes
continuation of acute inflammation lasting 2
weeks or longer.
chronic inflammation
