Neutrophils: Swift responders to bacterial infections, engulfing and neutralizing pathogens.
-
Lymphocytes: Key players in adaptive immunity, comprising T cells, B cells, and natural killer (NK) cells.
-
Monocytes: Precursors to macrophages and dendritic cells, involved in antigen presentation and immune regulation.
-
Eosinophils and Basophils: Combat parasitic infections and modulate allergic responses.
The Immune Orchestra: Functions of White Blood Cells
White blood cells orchestrate a symphony of immune responses, ranging from rapid pathogen clearance to the establishment of immunological memory for long-term protection.
-
Phagocytosis: Engulfment and destruction of pathogens by neutrophils, monocytes, and macrophages.
-
Antibody Production: B cells generate antibodies to target specific pathogens and toxins.
-
Cell-Mediated Immunity: T cells coordinate immune responses and eliminate infected or abnormal cells.
-
Inflammatory Responses: Release of cytokines and mediators to recruit and activate immune cells.
Guardians of Health: Role in Immunity
White blood cells serve as the vanguards of immunity, patrolling the body to detect and eliminate threats while maintaining tolerance to self-antigens.
-
Surveillance and Detection: Constant monitoring for signs of infection or abnormal cellular behavior.
-
Immunological Memory: Generation of memory cells for rapid and robust responses upon re-exposure to pathogens.
-
Tolerance and Self-Recognition: Discrimination between self and non-self antigens to prevent autoimmune reactions.
Pathology and Disorders
