During which phase of wound healing does contraction occur?

Contraction occurs during the proliferation phase of wound healing. This phase is characterized by the formation of granulation tissue, the proliferation of fibroblasts, and the movement of myofibroblasts to the wound area. Myofibroblasts are specialized cells that have contractile properties, enabling them to pull the edges of the wound closer together. This contraction reduces the size of the wound and is critical to the healing process.

During the proliferation phase, the body focuses on rebuilding tissue and filling in the wound with new cells, which not only helps to close the wound but also contributes to the overall healing process. This phase is essential for restoring the integrity of the skin or tissue affected by the injury.
