Question

Find the correct descending order of percentage preparation of leukocytes in human blood
A) neutrophils- basophils- lymphocytes- Acidophils- monocytes
B) monocytes- neutrophils- Lymphocytes-Acidophiles-basophils
C) neutrophils- lymphocytes -monocytes- Acidophils- basophils
D) Lymphocytes-Acidophils -basophils- neutrophils -monocytes

Answer 1

Hint: The leukocytes are the type of blood cells that are made in the bone marrow and found in the blood and lymph tissue. Leukocytes are part of the body’s immune system. They help the body to fight infection and other diseases caused by all types of leukocytes are granulocytes that are neutrophils, basophils, monocytes, and lymphocytes. checking the number of leukocytes in the blood is usually a part of a complete blood cell test. It may be used to cook a condition such as infection, inflammation allergies, and leukemia.

Complete step by step answer:
The white blood cells or leukocytes are classified into two groups that are granulocytes and non-granulocytes. The granulocytes which include neutrophils eosinophils and basophils have granules in their cell cytoplasm. Neutrophils, eosinophils, and basophils also have a multi-logged nucleus as a result they are called polymorphonuclear leukocyte or polys. The lifespan of WBC ranges from 13 to 20 days after which time they are destroyed in a lymphatic system. To measurements of white blood cells are commonly done in a CBC:
White blood cells in the microlitre(1 x10⁶) of blood reported as an absolute number of X mm of white blood cells and the percentage of each of the five types of white blood cells. This test is known as differential and is reported in percentages.
Normal Values for total WBC and differential in adult, males, and females are:
Total WBC:4500-10000
Bands or stabs:3-5%
Granulocytes/Neutrophils:50-70% relative value.
Eosinophils:1-3% relative value
Basophils:0.4-1%
Lymphocytes-25-35% relative value
Monocytes-4-5% relative value
Thus, the answer is option C:neutrophils- lymphocytes -monocytes- Acidophils- basophils

Note: The number of leukocytes changes with age and during pregnancy. On the day of birth, a newborn has a high white blood cell count ranging from 9000 to 30000 leukocytes. This number falls to adult levels within 2 weeks and the percentage of neutrophils is high for the first few weeks after birth but then lymphocytes' pre-dominance is seen.
