Physiological healing is the restoration of damaged living tissue, organs and biological system to normal function. It 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 new cells that form similar tissue as was originally there.
by repair: injured tissue is replaced with scar tissue.
Most organs will heal using a mixture of both mechanisms.

Regeneration

In order for an injury to be healed by regeneration, the cell type that was destroyed must be able to replicate. Cells also need a collagen framework along which to grow. Alongside most cells there is either a basement membrane or a collagenous network made by fibroblasts that will guide the cells’ growth. Since ischaemia and most toxins do not destroy collagen, it will continue to exist even when the cells around it are dead.
