White blood cells, also known as leukocytes, help defend our body against infection and disease.
These important blood cells are produced in the bone marrow and circulate in the bloodstream, searching for and destroying harmful pathogens like viruses and bacteria.
There are different types of white blood cells, each with specific functions, such as engulfing foreign substances, producing antibodies, or identifying and attacking infected cells.
The number of white blood cells in the body can indicate overall health, as they play a crucial role in maintaining a functioning immune system.
