Multiple Choice

Which statement about the healing phases is true?

Healing involves inflammatory, proliferative, and remodeling activities, but they don’t unfold in rigid, non-overlapping steps. The inflammatory response clears debris and sets up a biochemical environment with cytokines and growth factors that not only handles cleanup but also signals repair cells. As soon as those signals are present, cells like fibroblasts and endothelial cells begin rebuilding tissue, forming new blood vessels and laying down extracellular matrix—even while inflammatory cells are still active. Remodeling then starts to reorganize and strengthen the new tissue, and this can begin before inflammation has fully resolved and can continue after the initial tissue has formed. Because these processes are driven by overlapping sets of signals and cell activities, they commonly coexist rather than occur strictly one after another. The overlap is a normal part of healing and varies with tissue type, injury severity, and whether the injury becomes chronic.
