- - - - Monocytes
        
        Phagocytose pathogens and present antigens.
        
        Differentiate into macrophages or dendritic cells.
        
        Largest WBC with kidney-shaped nucleus.
      - Lymphocytes
        
        Types:
        
        NK cells: Destroy virus-infected or tumor cells.
        
        B cells: Humoral immunity (antibody production).
        
        T cells: Cellular immunity (e.g., cytotoxic response).
        
        Large, round nucleus with minimal cytoplasm.
    - - Basophils
        
        Release histamine in allergic and inflammatory responses.
        
        Bilobed nucleus, dark blue granules.
      - Eosinophils
        
        Defend against parasites and modulate allergic reactions.
        
        Bilobed nucleus, red cytoplasmic granules.
      - Neutrophils
        
        Phagocytose bacteria; first responders in inflammation.
        
        Multi-lobed nucleus, pale cytoplasmic granules.
  - - - Perform similar functions to mammalian platelets.
      - Nucleated cells.
    - - Essential for clotting and wound repair.
      - Non-nucleated cell fragments.
  - - - Found in birds, reptiles, amphibians.
      - Nucleated, oval-shaped.
    - - Lifespan: ~120 days.
      - Adapted for oxygen transport via hemoglobin.
      - Anucleated, biconcave disks.
- - - - Transports nutrients, hormones, and waste products.
      - Maintains blood pressure and volume.
