inflammation and repair Flashcards
components and stages of acute inflammation
1) . hyperemia- vasodilation = swelling and pain
2) . increased viscosity
3) . stasis
4) . increase in permeability allows cells to enter and leave
benefits of exudate
dilution of toxins
increase in pain from swelling
Abs at injury site
high content of proteins which increase phagocytosis
serous inflamation
water escapes but no fluid
cyst vs abbess
cyst is a fluid filled sac
abcess is localized exudate
hemorhagic inflammation
blood is in the cellular debris fluid
formed elements move into central column parallel to long axis
leukocytes move into outside of cell
pavementing and adhesions
wbc adhere to the endothelial lining
endothelium becomes sticky when damaged
leukocytes move into tissues
emigration
leukocytes slide along endothelial surface until they reach a gap
gap widens and slightly allows leukocytes to move along basement membrane untill they can pass into tissues
diapedesis
describes movement of RBCs
RBCs forced out by blood hydrostatic pressre
these RBCs typically die
