Detailed explanation-1: -Begins right after the injury when the injured blood vessels leak transudate (made of water, salt, and protein) causing localized swelling. Inflammation both controls bleeding and prevents infection. The fluid engorgement allows healing and repair cells to move to the site of the wound.
Detailed explanation-2: -Phase 1: Stop the bleeding (hemostasis) 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.
Detailed explanation-3: -Inflammatory phase – This phase begins at the time of injury and lasts up to four days. It includes clotting of platelets and constriction of blood vessels to stop blood loss, in addition to the arrival of white blood cells to kill bacteria and naturally clean the wound site.
Detailed explanation-4: -The normal wound healing process can be divided into 4 overlapping phases: coagulation, inflammation, formation of granulation tissue (proliferative phase), and remodeling or scar formation.
Detailed explanation-5: -Acute-swelling stage. Sub-acute – regenerative stage. Chronic – scar tissue maturation and remodelling stage.
