We just learned about the Neutrophil.

Another type of white blood cell is the Eosinophil, pronounced like "ee-oh-sin-oh-fill".

We've learned about 3 other types of white blood cells (WBC):
- lymphocytes - that help kill off bad diseases using T, B or NK cells.
- monocytes - that help fight off infections and clean up garbage in the body.
- neutrophils - most common WBC that is the first line of defense for fighting infections.

Less than 3% of the WBCs in the body are eosinophils.
They help fight viruses, and they also help the body fight off allergic responses.

One big difference is that these eosinophils live in tissues, they are not floating around in the blood stream.
They hang out in places like the intestines and spleen, but they do not go into the lungs, skin or esophagus.
