What are immune defenses?

Immune defenses are your body’s special team of protectors that keep you healthy by fighting off invaders like germs and viruses.

Imagine you’re playing in a park, and suddenly someone tries to take your favorite toy. You shout, “No way!” and push them away, that's kind of how immune defenses work. When something bad comes into your body, like a germ from a sneeze or a virus from touching a doorknob, the immune defenses jump in to stop it.

Think of your body as a castle. The immune defenses are like the guards at the gate. If someone sneaky tries to get inside, the guards check them out and either let them pass or fight them off.

Sometimes, the guards need help from friends who come running when they see trouble, that’s how your body gets better when you’re sick. These helpers are called white blood cells, and they're like superheroes with special powers to catch germs and viruses in action!

So every time you stay healthy, it's because your immune defenses did their job, just like a great team of guards protecting a castle.
