The immune system is like a superhero team that lives inside your body and fights off bad guys called germs.
Imagine you're playing in the park, and suddenly someone bumps into you, that’s like a germ coming into your body. Your immune system jumps into action to stop them from making you sick.
How the Immune System Detects Germs
Your immune system has special detective cells called white blood cells. They can spot germs, just like you can tell when someone is being mean in a game. When they find a germ, they send out an alarm to other parts of your body.
How the Immune System Fights Germs
Once the alarm goes off, more superhero soldiers come to help, some of them are like tiny machines that destroy germs, and others remember which germs you’ve already fought before. That’s why you might not get sick from the same germ again, your immune system remembers it!
Sometimes, when there are a lot of germs, you feel tired or have a fever, that's just your body working hard to win the battle!
