which phase of healing begins about 3 weeks after injury
Wound healing When the levels of collagen production and degradation equalize, the maturation phase of tissue repair is said to have begun.[20] During maturation, type III collagen, which is prevalent during proliferation, is replaced by type I collagen.[17] Originally disorganized collagen fibers are rearranged, cross-linked, and aligned along tension lines.[32] The onset of the maturation phase may vary extensively, depending on the size of the wound and whether it was initially closed or left open,[28] ranging from approximately 3 days[42] to 3 weeks.[58] The maturation phase can last for a year or longer, similarly depending on wound type.[28]

Pulse Pressure waves generated by the heart in systole move the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave.
