White Blood Cells
Say: wite blud sels
White blood cells are part of the germ-fighting immune system. They are like little warriors floating around in your blood waiting to attack invaders, like viruses and bacteria. You have several types of white blood cells and each has its own special role in fighting off the different kinds of germs that make people sick.
