PATHOLOGY

Detailed explanation-1: -The wound healing process is usually characterized as four sequential but overlapping phases: haemostasis (0–several hours after injury), inflammation (1–3 days), proliferation (4–21 days) and remodelling (21 days–1 year) [1].

Detailed explanation-2: -Inflammation, the next stage of wound healing occurs within the first 24 hours after injury and can last for up to 2 weeks in normal wounds and significantly longer in chronic non-healing wounds (Figure 23.3).

Detailed explanation-3: -The inflammatory response following tissue injury plays important roles both in normal and pathological healing. Immediately after injury, the innate immune system is activated, setting in motion a local inflammatory response that includes the recruitment of inflammatory cells from the circulation.

Detailed explanation-4: -The first stage of wound healing is for the body to stop the bleeding. This is called hemostasis or clotting and it occurs within seconds to minutes after you suffer a wound.
