Acid attack
Glands inside
your stomach
make acid, which
kills germs you’ve
swallowed. Your
digestive system then
breaks down the germs
along with your food.
Yuk!
The feeling of disgust protects you from
germs. Anything that smells revolting or
looks horrible is probably full of germs.
Disgust stops you from touching it.
Slimy guts
The inside of your intestines are
covered with slimy mucus, which stops
germs from getting into your blood.
Your large intestine also contains
millions of “friendly” bacteria, which
prevent other germs from growing.
