Neutrophil, Basophil, Eosinophil
What are the type of WBCs that are agranulocyte?
Lymphocyte and Monocyte
This blood cell makes up 50-70% of the WBCs.
Neutrophil
This blood cell’s nucleus has ~3-7 lobes.
Neutrophil
This blood cell has a clear-ish cytoplasm.
Neutrophil
This/These blood cell(s) is/are phagocytic.
Neutrophils and Eosinophils
This blood cell makes up 2-4% of WBCs.
Eosinophil
This blood cell is often 2-lobed.
Eosinophil
This blood cell’s cytoplasm contains pink/red granules (that are about the same color as the RBCs).
Eosinophil
This blood cell increases due to parasites and allergies.
Eosinophil
This/These blood cell(s) is/are phagocytic.
Eosinophils and Neutrophils
This blood cell causes allergic reactions
Basophil
These blood cells make up less than 1% of WBCs.
Basophils
These blood cells have “U” or “S”-shaped nucleus with indentations.
Basophils
This blood cell releases histamines and heparin.
Basophils
This blood cell causes allergic reactions and inflammation.
Basophil
What are the type of WBCs that are agranulocyte?
Lymphocytes and Monocytes
This blood cell accounts for 25% or more of WBCs.
Lymphocyte
This blood cell’s nucleus is about the same size as RBC.
Lymphocyte
This blood cell’s nucleus is spherical.
Lymphocyte
With this blood cell, you may see a small crescent of cytoplasm.
Lymphocyte
These cells are the primary immune cells.
Lymphocyte (B & T Lymphocytes)
These blood cells account for 3-8% of the WBCs.
Monocytes
This blood cells displays abundant cytoplasm.
Monocyte
This blood cell’s nucleus is usually slightly lighter than others.
Monocyte
These blood cells become macrophages (tissue phagocytes).
Monocytes

150,000 - 400,000/µl (microliters) of blood
These cells (fragments) are derived from Megakaryocytes.
Platelets
These cells (fragments) function in blood clotting.
Platelets
These cell fragments are not “real” cells.
Platelets
