The human body is like a team of workers who fix things when they're broken. When you hurt yourself, like cutting your skin or breaking a bone, special cells rush to the injured spot and start rebuilding it, just like workers fixing up a house after a storm. Simple healing means the body uses what it has, like skin cells for cuts or bone cells for breaks, so things grow back over time.
Examples
- If you cut your finger, new skin grows from the inside out like a flower opening up.
- When a bone breaks, it’s like a puzzle: pieces move apart and then fit together again with help from special cells called osteoblasts.
- A burn on your hand is like a map that gets erased and then redrawn by fresh skin cells.
