Briefly describe the steps in deep wound healing

What will be an ideal response?


In deep wound healing, a blood clot forms during the inflammatory response and loosely unites the wound edges. Then in the migratory phase the clot becomes a scab and epithelial cells migrate beneath the scab to bridge the wound. Fibroblasts migrate along fibrin threads and begin synthesizing scar tissue and damaged blood vessels begin to regrow. During this phase, the tissue filling the wound is called granulation tissue. The proliferative phase is characterized by extensive growth of epithelial cells beneath the scab, deposition by fibroblasts of collagen fibers in random patterns, and continued growth of blood vessels. During the maturation phase, the scab sloughs off once the epidermis has been restored to normal thickness. Collagen fibers become more organized, fibroblasts decrease in number and blood vessels are restored to normal.
