Germ Castle Invasion
How do germs get inside the body?
Your body is like a castle with walls, gates, and guards everywhere. It's designed to keep invaders out. But germs are tiny, sneaky creatures — bacteria and viruses smaller than a dot on this page — and they've learned every trick in the book to slip past your defenses and set up camp inside.
The easiest way in? Through your nose and mouth. Every time you breathe, you're opening the front door. When someone sneezes near you, they launch thousands of germ-filled droplets into the air like tiny water balloons. You breathe in, and whoosh — some germs ride that air straight down into your throat and lungs.
