Bacterial elimination occurs during which stage of wound healing?
Show answer and explanation
Correct answer: A. Migration stage

- B. Incorrect. Proliferation involves fibroblast activity, angiogenesis, and tissue repair — not primary bacterial clearance.
- C. Incorrect. Remodeling involves collagen cross-linking and scar maturation, occurring after infection control.
- D. Incorrect. Migration refers to epithelial cell movement across the wound surface, not bacterial elimination.
