Options:
Answer:
Solution:
The most abundant leucocyte (neutrophil) is a granulocyte, whereas the least abundant leucocyte (basophil) is also a granulocyte. The largest leucocyte (monocyte) is an agranulocyte, whereas the smallest leucocyte (lymphocyte) is also an agranulocyte. Phagocytic leucocytes are neutrophils (granulocyte) and monocyte (agranulocyte). Polymorphonuclear leucocytes (neutrophils) are the largest granulocytes, whereas the largest agranulocyte (monocyte) has a kidney shaped nucleus.
