What are the four phases of healing?

• A. Inflammation, Proliferation, Remodeling, Maturation
• B. Hemostasis and inflammation, Epitheliazation, Proliferation, Remodeling
• C. Coagulation, Inflammation, Healing, Restoration
• D. Dissolution, Replacement, Formation, Consolidation

Answer: (B)

The sequence of healing starts with stopping the bleed and cleaning up the wound, which is hemostasis followed by inflammation. This initial stage sets the stage for repair by forming a clot, preventing further bleeding, and bringing in immune cells to fight infection. Next comes epithelialization, where epithelial cells migrate across the wound bed to reestablish a protective skin barrier. After that, the proliferative phase builds new tissue—fibroblasts lay down collagen, new blood vessels grow, and granulation tissue fills the wound while the surface continues to be covered. Finally, remodeling (maturation) reorganizes the newly deposited collagen, increasing tissue strength and reducing scar tissue over time. This order—and the inclusion of a distinct epithelialization step within the healing process—best fits how healing progresses, whereas the other options either omit a key phase, misuse terminology, or describe processes that don’t align with the standard sequence.
