vessels then dilate to allow essential cells:
antibodies, white blood cells, growth factors,
enzymes and nutrients to reach the wounded
area.

Occurs once the wound has closed.
This phase involves remodelling of collagen, reducces of cellular activity and decrease the number of blood vessels in the wounded area.
