Detailed explanation-1: -In the proliferative phase, the wound contracts as new tissues are built. In addition, a new network of blood vessels must be constructed so that the granulation tissue can be healthy and receive sufficient oxygen and nutrients.
Detailed explanation-2: -In the proliferation phase, the provisional wound matrix formed during haemostasis is replaced by granulation tissue, consisting of a large amount of fibroblasts, granulocytes, macrophages, blood vessels, in complex with collagen bundles, which partially recovers the structure and function of the wounded skin [35].
Detailed explanation-3: -In the proliferation stage, your body creates scar tissue to repair your injury. This phase of healing starts within 24 – 48 hours, peaks at around 2 – 3 weeks after your injury and stops after around 4 – 6 months. This is the reason why you will still be experiencing symptoms a couple of weeks after your injury.
Detailed explanation-4: -Inflammatory Phase The fluid engorgement allows healing and repair cells to move to the site of the wound. During the inflammatory phase, damaged cells, pathogens, and bacteria are removed from the wound area.
