How Does the Human Body Repair Itself After an Injury?

Imagine your body is like a magical building that can fix itself when it gets hurt. When you get a scrape or a broken bone, your body sends special helpers, called cells, to the injury site to start repairing it. These cells build new tissue and help the damaged parts grow back strong, just like a team of workers fixing up a house after it falls apart.

Examples

  1. If you scrape your knee, it starts to bleed, then a scab forms, that’s the body fixing itself.
  2. When you break your arm, it feels sore at first, but after some time, it gets stronger again.
  3. Your skin heals faster than your bones because it doesn’t need as much work.
