WBC Full Form

The WBC Full Form is White Blood Cells. They are the most important component of the body’s immune system. They help in fighting infections and other diseases. The WBC Full Form White Blood Cells are created in the bone marrow and are helpful in fighting off diseases and infections.

What is the Full form of WBC?

The WBC Full Form stands for White Blood Cells and are found in blood and tissues in the body. A decrease in the number of White Blood Cells leads to less immunity in a person’s body. It is essential for every individual to maintain the WBC count to the optimum number. The number of White Blood Cells in the body can be checked by going through a complete blood test.

Composition and Meaning of WBC

The immune system includes WBC Full Form White Blood Cells (WBCs). They support the body’s defences against infection and other foreign substances. The functions of various White Blood Cells types vary. Some are tasked with identifying intruders. Some destroy dangerous bacteria. Others create antibodies to shield your body from exposure to viruses and bacteria. Many of modern vaccines are highly effective because of B lymphocytes. T lymphocytes are the main players in some situations, such as the vaccination against pertussis and tuberculosis.

Types of WBC in the Body

There are various types of WBC Full Form in the body. They are divided into three categories, granulocytes, lymphocytes and monocytes. Granulocytes are further divided into three different categories- neutrophils, eosinophils and basophils. All of them collectively protect the body from harmful substances.


The specific identification of foreign substances and their subsequent expulsion from the host are carried out by lymphocytes. They are further subdivided into B cells and T cells. Antibodies are proteins that B lymphocytes secrete that bind to foreign microorganisms in body tissues and facilitate their eradication. Typically, T cells identify cancerous or virally-infected cells and kill them, or they act as helper cells to aid B cells in producing antibodies. Natural killer (NK) cells, so named for their innate capacity to kill a variety of target cells, are also a part of this group. In a healthy individual, lymphocytes make up between 25 and 33 percent of White Blood Cells.


White Blood Cells which are called monocytes are found in the blood and tissues. They are responsible for identifying and eradicating pathogens like viruses, bacteria, fungi, and protozoa as well as infected cells. Monocytes along with other White Blood Cells treat wounds and fend off infections. Monocytes originate from the bone marrow and grow there until they are mature. After attaining maturity, they travel to the bloodstream to fight off germs and other foreign substances. 


These are the most common type of WBC Full Form White Blood Cells. Neutrophils are functional in capturing and destroying off bacteria and other harmful substances by ingesting them. After this, the body reacts by showing redness and swelling. It also repairs the damaged tissues and cells in the body.


Eosinophils help in removing foreign objects. Foreign substances can be consumed by eosinophils. For instance, they combat substances connected to a parasitic infection that the immune system has designated for eradication.

It also plays a key role in controlling inflammation. Eosinophils aid in the promotion of inflammation, which is helpful in isolating and managing a disease site. However, excessive inflammation can occasionally result in bothersome symptoms or even tissue damage. Eosinophils, for instance, play an important role in the development of asthma and allergy symptoms like hay fever. Other immune system conditions can also be a factor in persistent (chronic) inflammation.


Basophils are categorised into White Blood Cells that are termed granulocytes. The granules present in them play a huge role in inflammation. Basophils have a short-term life span, and they only live between a few hours to a few days. 

WBC Count Test

People need to get tested for the number of WBC Full Form in their blood. This can be done by getting tested for a complete blood test. Generally, a blood sample is taken, and then it undergoes a series of tests in the labs to determine the number of WBC Full Form present in the blood. The Full Form of WBC is White Blood Cells.

Range of WBC Count 

The normal range of WBC Full Form White Blood Cells in the body is from 4500 to 11000 per microlitre of blood. It is crucial to maintain the normal range of White Blood Cells to be free from germs and diseases.

Significance of WBC in Blood

As living cells, WBC Full Form White Blood Cells must continually produce energy in order to survive. The used chemical pathways are more complex than those of red blood cells and are the same as other tissue cells. Protein can be produced by white cells that have a nucleus and can produce Ribonucleic Acid (RNA).

FAQs (Frequently Asked Questions)

1. What Is The Full Form of WBC and its significance?
