    Study Notes

    CO2 Transportation and Excretion

    • CO2 is produced in tissues as a waste product of respiration.
    • CO2 is excreted in the lungs.
    • CO2 is transported in the blood in three forms:
      • Dissolved
      • Bicarbonate
      • Carbamino compounds
    • Deoxygenated haemoglobin is able to carry more CO2 than oxygenated haemoglobin.
    • Removal of carbon dioxide is vital to maintain a normal acid-base balance.
