Which is the correct sequence of arrangement of types of WBC in decreasing order in terms of number per mm3 of human blood?
A
Eosinophils > Basophils > Neutrophils
B
asophils > Eosinophils > Neutrophils
C
Neutrophils > Eosinophils > Basophils
D
Eosinophils > Neutrophils > Basophils
Answer
Neutrophils > Eosinophils > Basophils
Explanation
Solution
The count of neutrophils or heterophils is 60-70% of total leucocytes, .i.e., 4000−5000 cells/mm3 of blood. Eosinophils or acidophils or oxyphils make 1-5% of total leucocyte count, .i.e., 70−300 cell/mm3, while basophils or cyanophils count is 0.5-2.7% of total leucocytes, ie, 35−150 cells/mm3 of blood.
