What are white blood cells?

White blood cells are like tiny soldiers that help your body fight off invaders.

Imagine you have a toy box full of different kinds of toys, some are small and fast, others are big and strong. Each one helps you play better in different ways. White blood cells are like those special toys, but inside your body. They help protect you from things like germs, which can make you sick.

What Do White Blood Cells Do?

Think of a germ as a sneaky visitor who comes into your body without asking. Sometimes they cause trouble by making you cough or feel sore. That's when white blood cells jump into action. They chase the germs around and try to catch them, just like how you might catch a friend who’s running away from you in the playground.

There are many types of white blood cells, some are like fast runners, others are like strong wrestlers. Each one has its own special job, but together they make sure your body stays healthy and happy.
