Inflammatory stage of wound healing

  • begins with the injury and lasts 3-6 days

  • controls bleeding with vasoconstriction, retraction of blood vessels, fibrin accumulation, and clot formation

  • delivering oxygen, WBCs, and nutrients to the area

  • macrophages engulf microorganisms and cellular debris

  • delayed when there is too much of this or when there is too little (debilitating disease)

New cards

Proliferation Stage of wound healing

  • lasts the next 3-24 days

  • replacing lost tissue with connective or granulated tissue and collagen

  • contracting the wound’s edges to reduce the area that requires healing

  • resurfacing of new epithelial cells
