      The immune system is the collection of cells that patrol your body keeping the peace and react if anything looks out of place. You know when you get a spot? They are white blood cells called neutrophils that fight any infection to keep you healthy.

      Did you know, restoring the peace in your body is called homeostasis!

    Ah I love this question! Okay so do you know every moment of your life you are under attack?! By pathogens called bacteria or viruses or fungus or other little teeny tiny things that want to enter your body and use your body’s food and energy for their own selfish gains! Sounds dramatic but its 100% true haha. This is where the immune system comes in! This system is pretty much a powerful army of special kinds of cells. These cells have really cool names as well, like Kieran mentioned the neutrophil. So, these powerful cells are patrolling your body night and day to fight against those bad pathogens for your life! Literally. Without this system you would just die. On the other hand, sometimes these immune cells can stop working properly and instead of fighting the bad pathogens, they accidentally think your body’s other cells are the bad guys and that’s when the body gets in trouble. This is called ‘autoimmunity’.
