Explain three ways in which red blood cells are adapted to their function

Answer:

- Absence of nucleus and other organelles to increase space for packaging of haemoglobin.
- Possession of haemoglobin which has high affinity for oxygen.
- Bi-concave shape to create large surface area hence more packaging of haemoglobin for combining with oxygen.
- Ability to change shape/flexible to enable them to pass through or squeeze through narrow
capillaries.
- Have carbonic anhydrase enzyme which increases #CO_2# transportation
