I am interested to know how exactly Wolverine's body regenerates/heals from wounds.
From what I understand about the 'human' body's healing is that it uses a complex system of metabolism and other processes1; but Wolverine's healing is powered by his healing factor2 or Hyper-regeneration.
How does his healing factor work? i.e. where does his body get the energy to power such regeneration?
The Hulk3 gets his "powers" (strength, mass etc) from an unlimited source via the cosmos4 (not exactly sure how this works, but I do get the concept); Is Wolverine's healing factor the same or a similar concept?
