Inflammation Flashcards
1
Q
Vascular Response
A
Transient vasoconstriction prolonged vasodilation ↑ hydrostatic pressure ↑ blood flow Opening of capillary beds ↑ Increased vascular permeability endothelium retract Leaking of plasma Oedema formation Haemoconcentration → stasis
2
Q
Cellular Response
A
Neutrophils monocytes → macrophages through the endothelial gaps → diapedesis chemotaxis Neutrophils chemotactic chemicals.
3
Q
Phagocytosis
A
chemotaxis engulfment phagosome formation fusion → phagolysome digestion by lysosomal enzymes
4
Q
Lymphatic drainage
A
lymphatic vessels open assisting excessive fluid drainage → inflammatory products → remaining antigens
antigen presenting cells present to immune system
5

inflammation
A
healthy tissue responds to injury to destroy and remove foreign substance
first 6-8 hours
6

factor cause tissue damage
A
injury-physical/thermal/radiation/electrical/chemical
infection
infraction
