The full form of WBC is White Blood Cell. Also known as leukocytes, WBCs are a crucial component of the immune system, defending the body against pathogens such as bacteria, viruses, and fungi.
Understanding White Blood Cells
White blood cells are produced in the bone marrow and circulate throughout the bloodstream and tissues. They play a vital role in fighting infection and maintaining overall health. WBCs achieve this primarily through the production of antibodies, specialized proteins that target and neutralize foreign invaders.
Several sources confirm this definition:
- MedlinePlus: https://medlineplus.gov/lab-tests/white-blood-count-wbc/ states that a white blood count measures the number of white blood cells (WBCs) in your blood. They are also called leukocytes and are part of your immune system.
- Cleveland Clinic: https://my.clevelandclinic.org/health/body/21871-white-blood-cells describes white blood cells as part of the immune system protecting the body from infection.
- Byju's: https://byjus.com/full-form/wbc-full-form/ explicitly states that the full form of WBC is White Blood Cell and that they act as a defense against pathogens.
- Numerous other sources (listed in references) corroborate this information.
There are five main types of white blood cells, each with specific functions in the immune response. A complete blood count (CBC) test measures the total number of white blood cells, and a differential count can specify the levels of each type.
