Introduction
Healing is the final stage in the inflammatory process. There are two major aims that are accomplished during healing.
The first is to restore the The second aim is to restore
continuity of tissue.
to the tissue.
In some cases, a return to function may not be possible, but by giving structural stability some functionality may be preserved. . Regeneration occurs when damaged tissue is replaced by cells of the same type as the originals. Generally, regeneration results in a return to normal function. There are two types of healing that may occur. The first type is called The second type of healing is called . Replacement occurs when damaged tissue is replaced by cells that are of another type than the original cells. Most often replacement involves a return to structural continuity through the formation of a connective tissue scar. In most cases of replacement normal function is not restored, though there may be some improvement in function as structure is stabilized and inflammation subsides. cells are those cells which regenerate constantly. Labile cells are regenerated easily after injury occurs. Epithelial tissues such as skin and the linings of the gastrointestinal and urinary tracts generally regenerate as their cells are constantly undergoing mitosis to replace cells that are being shed. Some types of cells are capable of regeneration while others are not.
