Granulocytes

Granulocytes are a category of white blood cells characterized by prominent cytoplasmic granules and a multi-lobed nucleus. The three main types are neutrophils (phagocytic first responders to bacterial/fungal infection), eosinophils (combat parasites and modulate allergic responses), and basophils (mediate allergic reactions). They are key components of the innate immune system, providing rapid defense through phagocytosis, degranulation, and cytokine release.
