4. Helps Fight Infection
White blood cells are critical players for the maintenance of good health. They protect the body by either destroying invading pathogens or producing antibodies to fight against infection. The spleen produces certain types of white blood cells called lymphocytes that help to protect the body from infection.
Other types of white blood cell called T. lymphocytes and B. lymphocytes, which are produced in the thymus gland and the bone marrow respectively, travel to the spleen from where they activate immune response and the production of antibodies to fight infection. This function, which takes place within the white pulp, makes the spleen an important component in the maintenance of good health.
