  • Types of Blood Cell
    • Erythrocytes (red blood cells)
      • Biconcave  discs - large surface area/ volume ratio
      • Filled with heamoglobin - combines with oxygen
        • No nucleus - more space for haemoglobin
      • Flexible - can flatten against capillary walls
        • Creates a shorter diffusion pathway
    • Neutrophils
      • Granular cytoplasm
      • Engulf microorganisms by  Phagocytosis
      • Lobed nucleus
    • Lymphocytes
      • Large, darkly stained nucleus
      • B lymphocytes - produce antibodies
      • T lymphocytes -  cell destruction
      • Clear cytoplasm
    • Monocytes
      • Large, bean shaped nucleus
      • become macrophagesin the tissues
        • Engulf microorganisms
