Question

In terms of descending order of percentage proportions of leucocytes in human blood, which one is correct?

• A. Neutrophils $\to$ lymphocytes $\to$ monocytes $\to$ acidophils $\to$ basophils
• B. Neutrophils $\to$ basophils $\to$ lymphocytes $\to$ acidophils monocytes
• C. Neutrophils $\to$ monocytes $\to$ lymphocytes $\to$ acidophils $\to$ basophils
• D. Neutrophils $\to$ acidophils $\to$ basophils $\to$ lymphocytes $\to$ monocytes

Answer 1

The correct option is A Neutrophils $\to$ lymphocytes $\to$ monocytes $\to$ acidophils $\to$ basophils

Cells	Percentage proportion of total leucocyte count	$Cells/m{m}^3$ of blood
Neutrophils	60-70%	4000-5000 cells/$m{m}^3$
Lymphocytes	20-40%	1500-2500 cells/$m{m}^3$
Monocytes	2-7%	200-700 cells/$m{m}^3$
Acidophils	1-5%	70-300 cells/$m{m}^3$
Basophils	0.5-2.7%	35-150 cells/$m{m}^3$

Thus, the correct answer is (A).
