How Does the Human Body Repair Itself After Injury?

Imagine your body is like a team of builders working together to fix a broken house. When you get hurt, special workers called cells come in and start mending the damage, just like painters and carpenters fixing up a room.

When you fall and scrape your knee, your skin gets damaged. Your body sends in healing cells, like little repair people who clean the wound and grow new skin to cover it.

First, the hurt area gets cleaned up by white blood cells. Then, other cells start making new tissue so the injury can heal completely.
