36. The process of tissue repair involved in the normal healing of a superficial wound is that first inflammation sets stage which means that the trauma causes the affected tissues to release inflammatory chemicals. Next, organization restores the blood supply. This means that through the process of organization, the blood clot is replaced by granulation tissue. Finally, regeneration and fibrosis effect permanent repair meaning that the surface epithelium begins to regenerate.
