A wound often results from the breakdown of the epidermal layer, which is one of the three layers that make up the skin. Wound healing is the process through which the skin heals. The wound healing process starts immediately there is a breakdown of the epidermal layer.
The human body has a complex system that patches up skin wounds. There are different wound healing stages, and every stage is vital for proper wound healing. There are also two different types of wounds, which are:
- Open Wounds: This is when the skin cracks or splits, and the tissue beneath the skin are exposed.
- Closed Wounds: This is when the underlying tissues of the skin might be damaged, but there is no split or crack on the surface of the skin.
Classifications of Wound Healing
There are two types of wound healing: primary and secondary healing.
- Primary Wound Healing: This is when the non-infected wound heals without any complication.
- Secondary Wound Healing: Secondary healing takes place when the wound healing process is interrupted by dehiscence, infection, or immune dysfunction.
There are also four stages of wound healing, which are:
- The Hemostasis Phase: This stage is to stop the bleeding. Blood clots form at this stage to prevent you from losing too much blood.
- Inflammatory Phase: This is the clotting and scabbing phase. Inflammation helps to control the bleeding and prevent infection.
- Growth and Proliferative Phase: At this stage, your body will rebuild the wound with new tissue made up of extracurricular matrix and collagen.
- Maturity Phase: This is the remodeling phase, and it continues to heal the wound even after it looks repaired and closed.
