Basophils release histamine and other inflammatory mediators during allergic responses, dilating blood vessels and increasing permeability to allow other immune cells to reach the affected tissue quickly. Eosinophils and Basophils: Masters of Inflammation and Allergy Eosinophils and basophils are less numerous but play vital roles in managing allergic reactions and parasitic infections.
How White Blood Cells Fight Infection and Respond to Pathogens
Conversely, a low count, or leukopenia, can signify bone marrow problems, autoimmune disorders, or the effects of certain medications, making regular blood work a critical tool for early disease detection. This class is subdivided into B cells, which produce antibodies that tag pathogens for destruction, and T cells, which directly attack infected cells and help regulate the immune response.
White Blood Cell Type Primary Function Typical Percentage Range Neutrophils Bacterial and fungal phagocytosis 50-70%. They are the immune system’s first responders, rushing quickly to sites of infection, particularly those caused by bacteria and fungi.
How White Blood Cells Fight Off Infection
Supporting Players in Immune Defense Beyond the primary responders, other white blood cells contribute specialized functions that ensure the immune system operates with precision and balance. White blood cells, or leukocytes, form the cornerstone of the human immune system, acting as the body’s vigilant defense force against invading pathogens.
