  • The Blood
    • Red Blood Cells
      • Carry oxygen
        • From the lungs to all cells in the body
      • Doughnut shape
      • Contain a red pigment (Haemoglobin)
        • Oxidised to create oxyhaemoglobin
          • Used to carry oxygen to cells
      • Don't have a nucleus
    • White Blood Cells
      • Change shape
        • To eat unwelcome microorganisms
      • Produce antibodies
        • To fight microorganisms
      • Produce antitoxins
        • to neutralise the toxins given off by microorganisms
      • Do have a nucleus
    • Platelets
      • Fragments of cells
      • Don't have a nucleus
      • Help the blood to clot
        • Prevent blood loss
        • Prevent infection
      • Lack of platelets causes severe bleeding and bruising
    • Plasma
      • Liquid
      • Carries everything
        • Red blood cells, white blood cells and platelets
        • Glucose and amino acids
          • From the gut to cells
        • CO2
          • From organs to lungs
        • Urea
          • From the liver to the kidneys
        • Hormones
        • Antibodies and antitoxins
          • From white blood celsl
