swelling
loss of function
what are the 5 steps of soft tissue repair
injury
bleeding
inflammation
proliferation
remodel
what happens in the bleeding stage of soft tissue repair
cell tissue is disrupted
what happens in the inflammation stage of soft tissue repair
mast cells produce histamines
prostaglandins are released
what happens in the proliferation stage of soft tissue repair
fibroblasts create collagen
angiogenesis (new blood vessels made)
what happens in the remodelling stage of soft tissue repair
refinement - type 3 collagen turns into type 1
what is the vascular response to inflammation
leaky vessels
what is vasodilation
blood vessels widen
what is vasopermeability
more blood can pass through the vessels
what causes swelling
dormant capillaries open to increase blood flow
