What is the 3 main phases of healing?
1. Inflammation phase
2. Proliferation phase
3. Maturation phase
What is inflammmation phase?
It's the first phase of healing.
prepares the wound for healing
Lasts 1-6 days from injury
What is proliferation phase?
second phase of healing.
rebuilds the damaged structures and strengthenes the wound
What is the maturation phase?
how long does it last?
3rd phase of healing
modifies the scar tissues into its mature form, 9 on (1-2 years)
Major events in inflammation phse?
3. clot formation
Major events in proliferation phase?
2. fibroplasias/ collagen production
3. wound contracture
Major events in maturation phase?
1. Synthesis/ lysis balance,
2. Collagen fiber orientation,
3. Healed injury
