Resource summary

RED BLOOD CELL (RBC)
  1. also known as Erythrocyte
    1. contain haemoglobin (Hb)
      1. makes them red
        1. transports oxygen from lungs to respiring tissues
        2. formation
          1. fetal stage
            1. liver cells
            2. birth onwards
              1. bone marrow
            3. shaped like a biconcave disk
              1. dent on each side increases surface area
                1. oxygen can diffuse quickly into or out of the cell
              2. very small
                1. diameter: 7 micrometer
                  1. Hb molecule close to the cell surface
                    1. diffuse easily
                    2. squeezes into the capillaries
                      1. brings oxygen as close as possible to the cells that require it
                    3. no organelles
                      1. more room for haemoglobin
                      2. Short lived
                        1. Flexible
                          1. deform so as to pass through narrow blood vessels
                            1. springs back to normal shape later
                            2. special cytoskeleton
                              1. mesh like network of protein fibres that allows it to be squashed into different shapes
