What is the correct order of the three healing phases?

• A. Inflammation → Proliferation → Remodeling
• B. Proliferation → Inflammation → Remodeling
• C. Remodeling → Inflammation → Proliferation
• D. Inflammation → Remodeling → Proliferation

Answer: (A)

Healing progresses through distinct phases in a logical sequence: inflammation, proliferation, then remodeling. Right after injury, the inflammatory phase activates to control bleeding and prevent infection, bringing in immune cells that clean debris and release signals that kickstart the repair process. This sets the stage for the next phase, where fibroblasts lay down extracellular matrix and new blood vessels form, creating granulation tissue and promoting epithelialization. As this proliferation unfolds, the wound gradually fills in with new tissue and strength begins to return. The final remodeling phase reorganizes and strengthens the newly formed matrix, converting collagen type III to type I and increasing tensile strength over weeks to months. So the order inflammation → proliferation → remodeling aligns with the actual sequence of events in wound healing. Starting with proliferation would skip essential cleanup and signaling, and remodeling cannot occur effectively until a collagen-rich matrix has been established during proliferation; thus the other sequences don’t fit the healing timeline.
