Medical grafting is like taking a magical piece of a plant or animal, and putting it into a person's body to help them heal.
Imagine if you have a boo-boo on your skin, like a cut or scrape. Your body usually heals itself over time, but sometimes it needs a little help.
That's when the doctors might use medical grafting. They can take a teeny-tiny piece of healthy skin from another part of your body, or from a donor who has kindly donated their skin.
They then put this healthy skin onto your boo-boo, like a little patch. Over time, your body will use this healthy skin to heal itself faster.
This also works with other body parts, like bones or even organs! If someone needs a new heart or liver, doctors can take it from someone who has passed away but donated their organs, and put it into the person who needs it.
The magical piece of plant or animal is like a little superhero that helps us heal faster and better.
