Question

Quizplus · Accepted Answer

Granulocytes are white blood cells that contain small cytoplasmic granules, and are divided into three types: neutrophils, eosinophils, and basophils. Polymorphonucleocytes refer specifically to neutrophils, which have a distinctive multi-lobed nucleus. Agranulocytes, on the other hand, do not contain visible cytoplasmic granules, and are divided into two types: lymphocytes and monocytes. Phagocytes are cells that can engulf and digest foreign particles or debris, and can be found in both granulocytes and agranulocytes. Mononuclear leukocytes refer specifically to agranulocytes with a single, non-lobed nucleus, such as monocytes and lymphocytes.
