Question

WBC are called _____ of our body

Answer 1

Hint: The WBC or white blood corpuscles are defense mechanisms of our body as they help in fighting various diseases inside our body. They are found in lesser amounts in blood along with the other components like plasma, RBC or red blood corpuscles. They are associated with the immunity of the body.

Complete answer:
The WBC plays an important role in our body. The white blood cells provide immunity to our body and help in fighting against various diseases, infections, allergies and certain foreign particles like a virus, bacteria, parasites etc. Hence, they can be called as the soldiers of our body.

Additional information:
There are five main types of blood cells present in our body. They are basophils, neutrophils, eosinophils, monocytes, and lymphocytes.

> Basophils- They are the cells which are mainly responsible for all the allergic reactions in our body. They defend our body against harmful parasites and bacteria by chemicals like heparin and histamine.

> Neutrophils - The second one is the neutrophils. Neutrophils are the most abundant type of white blood cell of mammals. They usually respond very quickly and are among the first to visit for damage control. Neutrophils mainly target the foreign bacteria and fungus that enters our body.

> Monocytes- They are the largest type of white cell. There are three types of monocytes present in human blood. They are further differentiated into macrophages, dendritic cells and foam cells in order to fight the foreign microbes that enter the body.

> Lymphocytes- These are the main types of cell found in the lymph. They are present in the fluid that circulates through the lymphatic system. They are of three types of lymphocytes, that is, the B cells, the T cells and natural killer cells. They are associated with the front line defense mechanism of the body.

Note: The white blood cells are also called leukocytes. There are several types of white blood cells or leukocytes present in our body. They are mainly lymphocytes and neutrophils. They exert various immune responses in our body to combat any disease. A low white blood cell count usually occurs in a human body due to viral infections which disrupts the work of bone marrow temporarily. Several congenital disorders which cause diminished bone marrow function can also cause deficiency of WBCs in our body.
