You trip in the school field and scrape your knee. Ouch! A tiny bit of blood appears.
But here's something amazing: you don't need glue or a needle and thread. Your body fixes the cut all by itself — like a tiny repair team rushing to the rescue.
Let's follow the repair team, step by step. Tap Next to begin! →
First, a little blood flows out. That might look scary, but it's actually helpful! The flowing blood washes out dirt and germs, like water rinsing sand off your hands.
Grown-ups also help by cleaning the cut with water and covering it with a plaster.
In your blood float millions of tiny helpers called platelets. When there's a cut, they rush over and stick together to build a plug that stops the bleeding.
Tap the floating platelets to send them to the cut. Fill the gap!
Air dries the plug and it turns hard and crusty. That crusty cover is a scab. A scab is like a natural plaster your body makes to protect the cut while it heals underneath.
Drag the slider to watch the plug dry and harden into a scab.
The scab is like a roof. Hidden safely under it, your body builds brand-new skin — cell by cell — to close the gap. This is the busiest part of healing, and it takes a few days.
Once the new skin is finished, the scab isn't needed anymore. It dries up and drops off on its own — showing fresh, healed skin.
Your scab feels a bit itchy. What should you do?
Picking a scab too early can let germs in and may leave a scar. Leaving it alone helps you heal neatly.
Now put the healing steps in the right order. Tap each step in the order it happens, from first to last.
Your body is an amazing repair team. Here's the whole story:
Remember: keep cuts clean, cover them, and be patient. Your body knows how to heal. 🩹💪
