Name the three phases of tissue healing.

• A. Hemostasis, Inflammation, and Regeneration
• B. Inflammation, Proliferation (Repair), and Remodelling (Maturation)
• C. Inflammation, Necrosis, and Scarring
• D. Proliferation, Inflammation, and Remodeling

Answer: (B)

The three phases of tissue healing are inflammation, proliferation (repair), and remodelling (maturation). After injury, inflammation starts to control bleeding and prevent infection, paving the way for new tissue formation. During proliferation, new tissue is built—fibroblasts lay down collagen, new blood vessels form, and granulation tissue and epithelial layers develop. In the final remodelling phase, the new tissue is reorganized and strengthened over time, with collagen realigned along stress lines and scar tissue maturation continuing for weeks to months. This sequence is the standard framework for healing, and the other options mix in phases that aren’t part of the classic three-phase model or place them in the wrong order.
