Biology - Body Fluids and Circulation Question with Solution | TestHub

The total white blood cell (WBC) count is given as $10000{\text{/mm}}^3$.

Different types of WBCs and their approximate percentages in human blood are:
Neutrophils: $60\%-65\%$ (can range up to $70\%$)
Lymphocytes: $20\%-25\%$
Monocytes: $6\%-8\%$
Eosinophils: $2\%-3\%$
Basophils: $0.5\%-1\%$

Calculating the approximate number of each type of WBC for a total count of $10000{\text{/mm}}^3$:
Neutrophils $\approx 6000-7000{\text{/mm}}^3$
Lymphocytes $\approx 2000-2500{\text{/mm}}^3$
Eosinophils $\approx 200-300{\text{/mm}}^3$
Basophils $\approx 50-100{\text{/mm}}^3$

Among the given options, $7000{\text{/mm}}^3$ correctly corresponds to the expected count of neutrophils.

Answer: $7000{\text{/mm}}^3$
