78How does a superficial wound (a paper cut) heal?
- ABasal cells move across the gap until contact inhibition occurs. The epidermal growth factor causes multiplication of the basal cells until the gap is filled.

79Deep wound healing:
Phase one: inflammatory phase:
The migration of [blank_start]leukocytes[blank_end] to clean up any microbes, foreign tissue and dead matter in the area. [blank_start]Thrombocytes[blank_end] come in to clot blood and form a [blank_start]platelet plug[blank_end].

- Cplatelet plug
- Dbasement membrane.

- Gcollagen fibres
- Hbasal cells

- Klipid
- Ldead tissue layer
- Mmacrophage cells
- Nmonocytes
- Ofibroblasts
80Deep wound healing:
Phase two: proliferation
[blank_start]Granulation tissue[blank_end] is formed with the reformation and laying of [blank_start]collagen fibres and blood vessels[blank_end]. They need to starting repairing tissue and creating new blood vessels. This is the stage of extensive growth, differentiation and repair of [blank_start]epithelial cells.[blank_end]- AGranulation tissue
- Bbasal tissue
- Cleukocyte tissue
- Dcollagen tissue
- Ecollagen fibres and blood vessels
- Fmacrophages
- Gleukocytes
- Hthe hypodermic layer
- Iepithelial cells.

81Deep wound healing:
Phase three: remodelling
this can take between [blank_start]3 to 6 weeks[blank_end]. The [blank_start]platelet plug[blank_end] begins to fall off and a scar tissue remains.- A3 to 6 weeks
- B3 to 6 days
- C3 to 6 months
- D3 to 6 hours
