Question

Identify the blood cells in the given figure and select the correct option regarding them.

• A. P represents basophil which releases histamine and heparin.
• B. Q represents eosinophil whose number increases in asthmatic people.
• C. R represents neutrophil which is phagocytic in nature.
• D. All of the above.

Answer 1

The correct option is D All of the above.

D. All of the above

EXPLANATION: Basophil, eosinophil and neutrophil are white blood cells. Basophil is responsible for the allergic reactions. They fight against the parasites and bacteria by excreting some chemicals, like histamine and heparin. Heparin is a blood-thinning substance and histamine can widen the blood vessels and can increases blood flow. Eosinophils modulate allergic inflammatory responses. The increasing number of eosinophil is associated with an increased number of asthma attacks. Neutrophils mainly target fungus and bacteria. They are most abundant type of WBC. They can respond and multiply quickly. Neutrophils are phagocytes, which can kill many microbes.
