What Do White Blood Cells Do?

The main job of our white blood cells is to detect and attack bacteria, viruses, fungi, parasites, and anything else that might otherwise cause harm to us. They are found flowing through the blood circulation and in lymph where they patrol the vessels looking for unwelcome guests.
They also occupy the lymph nodes and other organs and glands, waiting to deal with any pathogens that pass by. Without them, our bodies would be much less effective at protecting themselves, and we will fall ill far more often. Without white blood cells, even usually mild diseases can become something severe.
