claimThe spleen filters circulating blood to detect pathogens, which triggers the activation and multiplication of immune system cells to neutralize those pathogens.
procedureNeutrophils circulate in the blood and migrate to areas where an invader has been identified, where they surround and ingest pathogens through a process called phagocytosis.
procedureDendritic cells are produced in bone marrow, migrate through the blood to tissues to monitor for pathogens, and upon encountering a pathogen, phagocytose it and present pieces of it as antigens on their surface.
