There are five different types of leukocytes: three types of granulocytes (eosinophil, basophil, and neutrophil) and two types of agranulocytes (monocyte and lymphocyte).

三种粒细胞（嗜酸性粒细胞，嗜碱性粒细胞和中性粒细胞）和两种无粒细胞（单核细胞和淋巴细胞）。

Unlike granulocytes, agranulocytes do not contain granules in their cytoplasm, nor do they have multi-lobed nuclei. Agrnulocytes are characterized by the presence of a single large nucleus. The two types of agranulocytes are monocytes and lymphocytes.

与粒细胞不同，无颗粒细胞在其细胞质中不含颗粒，也不具有多叶核。无颗粒细胞的特征在于其存在一个大核。两种类型的粒细胞是单核细胞和淋巴细胞。
