986 - How does our immune system protect us from diseases?

Your immune system is like a superhero that protects your body from bad guys like germs and viruses. Here's how it works:

1. Recognition: Your immune system recognizes invading germs or viruses, like a wanted poster in a post office.
2. Alert system: It sends a message to your immune cells, like a call to action, saying " danger, danger!"
3. Army of soldiers: Your immune cells (like white blood cells) rush to the site of the invasion to fight the bad guys.
4. Fighting: Your immune cells use special powers to kill or capture the germs or viruses.
5. Removal: Your immune system removes the dead germs or viruses from your body, like cleaning up the battlefield.
6. Memory: Your immune system remembers the invading germs or viruses, so it can recognize and fight them again if they come back.

This is a simplified explanation of how your immune system works. It's a really smart and powerful system that keeps you healthy!
