Journeys: Skin. Stop 5
Skin shield
Germs are flying at the skin! Cover the scratches with plasters before a germ gets in.
See? Germs bounce off skin that has no cuts. It's like a shield.
A scratch! Tap it to cover it with a plaster.
A germ got into the scratch! A white cell is already catching it.
Every day, skin stops loads of germs. And a plaster protects a scratch while new skin grows underneath.
