What are granulocytes used for?
Eosinophils, basophils and neutrophils are called granulocytes due to the presence of cytoplasmic granulations. Lymphocytes and monocytes, on the other hand, are agranulocytes. Lymphocytes, in turn, are divided into multiple subtypes, including T lymphocytes, B lymphocytes and NK (Natural Killer) lymphocytes.

Low neutrophils may depend on the following pathophysiological mechanisms: 1) Defect in the production of neutrophil granulocytes: it can be the expression of a nutritional deficiency (e.g. vitamin B12) or of a neoplastic orientation of the hematopoietic stem cell (e.g. myelodysplasia and acute leukemias).
Where do granulocytes mature?
The granulocytes can be found: in the medulla, as a reserve that is poured into the circulation as needed; in the blood, as circulating cells; in the tissues, where they migrate from the blood by leukocyte extravasation, attracted by chemotactic factors released in case of infection.
What does it mean to have low neutrophil granulocytes?
When neutrophils are low, the body is more susceptible to infections, especially bacterial ones. Leukopenia and granulocytopenia are often used as synonyms for neutropenia, but strictly speaking they are not quite equivalent.
