Hemostasis 

  • the skins first response to 2 immediate threats

  • Physical barrier of the epidermis has been compromised 

                       




               Vasoconstriction 

-blood vessels tighten to minimize bleeding 

-forms blood clots

-fibrin protein forms cross-links on the top of the skin preventing blood from flowing out and bacteria or pathogens from getting in





Inflammation 

  • White blood cells(macrophages) devour bacteria and damaged tissue


Phagocytosis - previously constricted blood vessels expand



Vasodilation - 2 to 3 days after the proliferative stage occurs when the fibroblast cells enter the wound 

-collagen deposition forms connective skin tissue to replace the fibrin 






remodeling (healing process)



Medical protection 


clean cloth or sterlie dressing to clean it




using pressure to aply to the wound
