Question

Find the correct descending order of percentage proportion of leukocytes in human blood
A. Neutrophils>basophils>lymphocytes>acidophils>monocytes
B. Monocytes>neutrophils>lymphocytes>acidophils>basophils
C. Monocytes>neutrophils>lymphocytes>acidophils>basophils
D. Lymphocytes>acidophils>basophils>neutrophils>monocytes

Answer 1

Hint: The leukocytes are the cellular components of the blood that defends the body against the infections by ingesting foreign materials some of the leukocytes are the first to appear at any infection and are large in number.

Complete answer:
-Neutrophils -There are five major types of leukocytes blood circulation: - They are multicellular cells and they are not limited to specific areas of circulation. They move freely in the blood and are first to attack all the antigens. Normal range 40-60.
-Lymphocytes – They are made from the bone marrow and come in the bloodstream and lymph tissue. They appear in the conditions for cold stress malnutrition exercise. Normal range-
30-40%.
-Monocytes- They are the largest leukocytes having kidney shape nucleus. They remove dead and damaged tissue and regulate the immunity. They increase in viral infections measles infectious mononucleosis. Normal range- 2-8%.
-Acidophil – They are the component of the immune system responsible for fighting multicellular parasite cancer, allergic reactions like asthma, hay fever etc. It promotes inflammatory reactions. Normal range -1-4%.
-Basophils- They are leukocytes from the bone marrow that keeps functioning of immune system functioning. They decrease in allergic reaction, increase in blood cancer. They are very less in count. Normal range- 0-2%.
So the correct option is C.

Note: Neutrophils are always the first to appear as defense against infections and are greater in number than others and basophils are always less in number they appear in rare conditions.
