Neutropenia, or a decreased in the White blood cell neutrophils, also seen as leukopenia or granulocytopenia.
Well, I'm not sure about how many cells we have, but the average human body makes about 259 billion red blood cells per day. (That's why I don't know). Also, there are about 200 different types of cells with about 20 different types of organelles.
Hope this helps!
