It regrows to the exact size it was, no extra skin no less skin. Unless of course it’s a serious injury but I’m talking minor skin removal. Obviously gunshot wounds, flesh eating bacteria and animal bites don’t do this because of scar tissue I assume but even with them it’s remarkable how close it comes to filling in the area. How does the body know when to stop growing the new tissue to fill it in and how come with these deeper wounds the body has a harder time figuring it out?
In: Biology
If you chop a chunk of your finger there is no way your body regenerates a new fingertip.
If you get a small cut then skin Bridges itself and starts to reproduce as always “pushing” any damage out. For a deep cut or a chopped limb the body just produces an ugly fiber which closes the wound in the shortest way possible.
Obviously not a doctor nor is English my first language.
