regeneration
Chapter: 3
Regeneration is a type of repair. The best example of healing by regeneration occurs in the liver, which has incredible regenerative properties. It is possible to resect virtually an entire lobe of liver, and the organ will repair itself over a period of months to completely recapitulate its previous structure. The skin is another good example of an organ that heals by regeneration. If the skin is injured, no scar will form unless the basement membrane is destroyed. This is easily seen in cases of chicken pox, where only pocks that become superinfected with bacteria from scratching will leave a scar.
