What is the final phase of wound healing?

• A. Inflammation
• B. Proliferation
• C. Remodeling
• D. Matrix deposition

Answer: (C)

The final phase of wound healing is remodeling. This phase follows the initial inflammatory and proliferative phases and is crucial for restoring the integrity and strength of the skin after injury. During the remodeling phase, which can last from weeks to several months or even years, collagen fibers that were laid down during the proliferative phase undergo reorganization and maturation. This process improves the tensile strength of the wound site, enhancing its function and appearance. Over time, the collagen fibers align along lines of stress, and the wound matures, leading to improved skin texture and color. This phase is vital for restoring the pre-injury state of the tissue, although the final structure may not have the same strength as the original skin. In contrast, the inflammatory phase serves to protect the body and prevent infection, while the proliferative phase focuses on tissue formation and re-epithelialization. Matrix deposition might occur during the proliferative phase but does not represent a distinct phase of healing like remodeling does.
