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

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
