Healing is the process by which the cells in the body regenerate and repair to reduce the size of a damaged or necrotic area. Healing incorporates both the removal of necrotic tissue (demolition), and the replacement of this tissue.
The replacement can happen in two ways:
by regeneration: the necrotic cells are replaced by the same tissue as was originally there.
by repair: injured tissue is replaced with scar tissue.
Most organs will heal using a mixture of both mechanisms.
