Answer:
The most frequently damaged tissues are the skin and mucosa, which causes the body to activate a repair process consisting of the following steps:
1- Inflammation: This process involves the cells of the immune system, white blood cells, antibodies, lymphatics. All these cells work together, once the vessels expand, they act producing an inflammation process where coinside these cells eliminating necrotic tissue, bleeding and coagulation is formed.
2- Organization: In this step, the clot begins to form in granulation tissue that is a tissue composed of several elements and that goes from the central part of the lesion to the periphery. In this stage new capillaries grow, fibrolastic tissues are formed that produce growth factors and collagen fibers.
3- Regeneration: A superficial epithelial tissue begins to grow under the granulation tissue. As the underlying fibrous tissue matures and becomes fibrous until it finally resembles the adjacent skin. Finally forming a fully regenerated epithelium.
Answer:
a. The bone matrix is very dense and contains deposits of calcium salts

The organic matrix is about 20 percent of the net weight of the bone and is composed mainly of collagen , hence collage is the main structural component of the bone matrix .
