🛡️ How do our bodies fight infections?

Our bodies are like superheroes 🦸‍♂️! When germs try to make us sick, our body has tiny soldiers called white blood cells that fight them. They gobble up the bad germs like Pac-Man! 🎮

Sometimes, we get a fever 🤒 or a runny nose 🤧—that’s our body working hard to kick out the germs!

Our body has an amazing defense system called the immune system! 🛡️ It’s like an army with different soldiers:

• White blood cells (like warriors) attack germs directly.
• Antibodies (like tiny detectives) mark germs so other cells can find them.
• Fever 🌡️ makes the body too hot for germs to survive!

When you get a vaccine 💉, it teaches your immune system to recognize germs before they make you sick!

The Immune System: Your Body’s Defense Army

When pathogens (like bacteria or viruses) invade, your immune system launches a multi-step attack:

1. Barriers: Skin 🌟 and mucus trap germs.
2. Innate Response: White blood cells (like neutrophils) swarm and digest invaders.
3. Adaptive Response: Specialized cells (T-cells and B-cells) create antibodies to target specific germs. This is why vaccines work—they ‘train’ your immune system!

Fever and inflammation are signs your body is fighting hard. Over time, your immune system remembers past infections for faster future protection!
