What type of cells do white blood cells produce?

White blood cells, also known as leukocytes, play a crucial role in the immune system by defending the body against infections and foreign substances. One of the primary functions of certain types of white blood cells, particularly B lymphocytes, is to produce antibodies. Antibodies are specialized proteins that recognize and bind to specific antigens, such as bacteria or viruses, marking them for destruction and neutralization. This process is essential for the adaptive immune response, which tailors the body’s defense to specific pathogens.

The production of antibodies by white blood cells is a key component of the body’s ability to remember previous infections, providing long-term immunity. Understanding this role helps clarify the importance of white blood cells in protecting against diseases and maintaining overall health.
