How do wounds know when to stop healing?

In: 2

So, imagine a wound is like a house fire. The smoke from the fire is like the signals to your brain that there is something wrong in that area. Once fire fighters get to that house, they put out the fire. That is like the platelets and white blood cells stopping the bleeding and fighting infection. After that, you need to rebuild your house. Only problem is, you can never make the same exact house that was the before. That’s why scar tissue is left. Once the house is finished building, it gets inspected. The body is the same way. Once the nerve cells stop sending the signal that something is wrong to the brain, the repairing cells leave to go build another house.
