List three types of WBC granulocytes.

Granulocytes are a subset of white blood cells distinguished by visible granules in their cytoplasm. The three granulocyte types are neutrophils, eosinophils, and basophils. Neutrophils are the most abundant and act as first responders, performing phagocytosis to engulf bacteria. Eosinophils fight parasitic infections and help regulate allergic inflammation. Basophils release histamine and other mediators that promote inflammation during allergic reactions and coordinate the immune response. The other choices mix in agranulocytes like lymphocytes and monocytes, which lack cytoplasmic granules, and erythrocytes, which are red blood cells, not white blood cells, so they don’t fit as granulocytes.
