What are immune cells?

Immune cells are like tiny soldiers that protect your body from invaders.

Imagine you have a toy box full of different kinds of toys, some are big and strong, others are small and sneaky. Each toy is like an immune cell, and they all have special jobs to do when something doesn’t belong in your body.

Some immune cells are like the brave soldiers who run out to fight the first invader they see. They’re called white blood cells, you can think of them as the front-line fighters in a big battle.

Other immune cells are more like smart detectives. They look around, find clues about the invaders, and send messages to call for help. These are like your body’s messengers, telling other soldiers where the trouble is.

Every time you get sick or have a scrape on your knee, these tiny soldiers are working hard, just like your favorite toy characters fighting off villains in your bedtime stories!
