How Our Bodies Heal?
Our bodies have the amazing innate ability to heal themselves. However complex this process may be, the body’s ability to detect disruption in its normal architecture and structure is just as amazing as its ability to know how to repair itself. A wound, in its most basic definition, is an injury to tissue caused by a cut, an impact, or other trauma in which tissue is damaged. Wound healing occurs through the following phases:
Inflammation is the body’s first response to injury. A blood clot forms, the wound contracts, and cells essential for repair are dispatched. Other vital repair components are also recruited, such as antibodies (for protection against bacteria), growth factors, and enzymes.
During this “proliferative” phase, the body essentially begins rebuilding the tissue. A new foundation made of collagen is laid down, and blood vessels begin to multiply to supply the wound with more necessary nutrients. Slowly, new replacement tissue, called “granulation tissue,” is generated. This tissue is recognizable as a light pink to red tissue where the original injury was.
In this final stage, the wound has closed and the new tissue is remodeled, fortified, and made stronger. Often, a scar forms from the replacement tissue.
