  • Erythrocytes carry oxygenated blood to different organs and transport carbon dioxide from tissues to lungs
  • Erythrocytes are derived from adult stem cells in the bone marrow
  • smooth surface and biconcave shape allows it to fit through capillaries easily
  • Erythrocytes lack organelles reducing its life span
  • large surface area to volume ratio allows more oxygen to be transported in the cells
  • the enzyme carbon anhydrase helps transport carbon dioxide from tissues to lungs
  • Erythrocytes circulate for 4 months before being destroyed in liver by phagocytes
  • erythrocytes
    • biconcave shape to increase surface area for diffusion and increase cell flexibility to fit through capillaries
    • no nucleus so can have space to carry more haemoglobin to increase transport of oxygen
