2.59 Red Blood Cells

1. if we had a cubic metre of blood we would have 5 x 10 to the 6 Red blood cells which means 5000000 red blood cells.
2. The shape-biconcave disc, this gives us short diffusion distance for oxygen.
3. Structure-There is no nucleus, this gives us more space for haemoglobin, Also their is no mitochindria.
4. These cells respire anaerobically therefore they do not use the oxygen they transport.
5. The presence of haemoglobin makes it easier to carry oxygen. Haemoglobin carry oxygen. Each haemoglobin carries 4 oxygen molecules.
