What happens in your body whenever you are injured?
- Starts after bleeding stops- Symptoms include; swelling, pain, redness, and heat - Increases blood flow and white cell production -> macrophages, neutrophils & manocytes removes bacteria and debris
- Collagen aligns and increases in number- Fibroblasts reduce size of damaged tissue - Blood vessels strengthen
Occurs 1-4 days after injury
Can take years to finish
Inflammatory
Remodeling
Start
Finish
Proliferation
Hemostasis
- Cells pull the edges of the wound close tg - Epithelial cells create a new matrix ->fibroblasts produce more collagen to replace fibrin clot ---excess will cause scarring - Appears healed - New blood vessels form
- Stops blood flow- Fibrin clot seals wound ->seal broken capillaries ->prevents infection - Plateles release growth factors(more cells)
Begins fast and lasts 2-3 hrs after injury
Lasts 4-21 days after injury
