Explanation:
Given diagram can be labelled as 1-basophil, 2- monocyte, 3- T-lymphocyte, 4-Neutrophil, 5- eosinophil, 6- B-lymphocyte. We have two main categories of WBCs granulocytes and agranulocytes. Neutrophils, eosinophils and basophils are different types of granulocytes, while lymphocytes (Both T-lymphocyte and B-lymphocyte) and monocytes are the agranulocytes.
