After Surgery, Trauma or a Really Fucked Up Day (also: After Noon)

Healing, assessed physically, 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.
