1000 - How does the immune system fight off infections?

Imagine your body has a superhero team to keep you healthy. This team is called the immune system. Here's how it works:

1. Recognize the enemy: The immune system finds the bad guys (like germs, bacteria, or viruses) that enter your body.
2. Send in the troops: White blood cells, like neutrophils and macrophages, come to fight the germs. They eat the germs or kill them with special powers.
3. Create a shield: The immune system makes antibodies, which are like special proteins that stick to the germs, marking them for destruction. This helps keep you safe from getting sick again.
4. Battle the germs: The immune system fights the germs using different methods, like creating fever to make the environment too hot for the germs to survive.
5. Win the fight: Once the immune system defeats the germs, it remembers them, so it can fight them off faster next time.

Remember, taking care of your immune system by eating healthy, exercising, and getting enough sleep can make your superhero team even stronger!
