Question 36-Outline the process of tissue repair involved in normal healing of a superficial wound.

1)The first step is inflammation. Once the tissue is hurt, the injured tissue cells, macrophages, mast cells, and others to release the inflammitory chemicals, which cause the capillaries to dilate and become permeable. The leaked clotting proteins construct a clot which stops the loss of blood and holds together the wound, and closes it up to prevent any infections.
2)The second step is for organization to restore the blood supply. During the blood clot, the clot is replaced by granulation tissue, which is a pink tissue made from many different elements. It has capillaries that grow in from the close by areas and lay down a new capillary bed. The macrophages digest the blood clot and collagen fiber continues. The granular tissue that becomes scar tissue is very resistant to infection from the bacteria inhibiting substances.
3)The last step is regeneration and fibrous effect permanent repair. During this, the epithelium starts to regrow, and the scab begins to fall off. It keeps growing and eventually it starts to look like the skin around it. If the wound is bad enough there will be a scar, or a thin white line, but most of the time it will dissapear.
