Healing phases of wounds |
Inflammation, proliferation, remodeling |
|
|
Inflammation phase |
Initial defense, limit damage to wound, remove debris, prepare wound for healing |
|
|
How long does inflammation phase last? How many stages does it have if any? |
2-5 days two stages |
|
|
First stage imflamm |
Blood vessels constrict to control blood loss, vessels dialate to bring platelets to wound forming a clot. Damaged cells leak plasma and chemicals that cause discomfort |
|
|
Second stage inflamm |
Wbc (leukocytes) travel to wound in big numbers several types include neutrophilis and monocytes |
|
|
Neutrophilis and monocytes perform what? What does it do? |
Perform phagocytosis=consumption (removal) of pathogens, clotted blood and cell debris *cleans wound preparing it for healing |
|
|
Proliferation phase |
Growth tissue occurs here from edges-inward new tissue can be fragile, through time collagen strengths wound. At the end of this phase, new blood vessels degenerate(no need) losing bright pink color |
|
|
Granulation tissue |
New tissue composed of new blood vessel, fibroblast, epithelial cells Highly vascular=bright color pink to red |
|
|
Name 3 various ways wounds heal |
Resolution, regeneration, scar formation |
|
|
Resolution |
Recover turning to their norm func. |
|
|
Regeneration |
New cells formed |
|
|
Scar formation |
Damaged cells replace w/nonfunc. Fibrous tissue (amt. Depend on damage and type wound heal) |
|
|
Remodeling phase |
Maturation of wound occur here. Tissue increases in strength DT synthesis of collagen by fibroblasts *scar tissue shrinks |
|
|
Name 3 types of wound heal processes |
First |
