How are leukocytes differentiated? - Answer Granulocytes:
- neutrophils
- eosinophils
- basophils
Agranulocytes:
- lymphocytes
- monocytes
What are characteristics of neutrophils? - Answer Most abundant leukocyte with multi lobed
nuclei (up to 5 lobes)
What are characteristics of eosinophils? - Answer Contain red or pink granules in cytoplasm
with bilobed nuclei- two lobes connected by a strand

and contains blue violet granules
, What are characteristics of lymphocytes - Answer Large round nuclei
What are characteristics of monocytes? - Answer Large kidney shaped nuclei
What makes up erythrocytes (RBCs)? - Answer 4.2-6.2 million per cubic mm
What are WBCs responsible for? - Answer Initiating an immune response
If you have type A antigens on your RBCs, and you receive anti-B antibodies, what will happen in
your blood smear? - Answer There will be no agglutination
