  1. Tissue: The Living Fabric Part D 4

  2. Tissue Trauma • Repair occurs in two major ways: • Regeneration: replacement of dead cells • Fibrosis: The growth of fibers (scar tissue) The type of repair that occurs depends upon the severity of the injury and the tissue that was damaged.

  3. Tissue Trauma • Causes inflammation, characterized by: • Dilation of blood vessels • Increase in vessel permeability • Redness, heat, swelling, and pain

  4. Tissue Repair • Organization and restored blood supply • The blood clot is replaced with granulation tissue Granulation Tissue is delicate pink tissue that contains capillaries and other fibers. Figure 4.12a

  5. Tissue Repair • Regeneration and fibrosis • Surface epithelium regenerates and the scab detaches • Fibrous tissue matures and begins to resemble the adjacent tissue Figure 4.12b

  6. Tissue Repair • Results in a fully regenerated epithelium with underlying scar tissue Figure 4.12c
