Adaptations of red blood cells to its function

1. They have a biconcave disc shape to increase the surface area for the absorption of oxygen. 2. They lack a nucleus, which permits hemoglobin to be packed into the cell. 3. They are small therefore able to squeeze between capillaries 4. They have a thin membrane permitting efficient diffusion of gases (short distance for diffusion) 5. They contain hemoglobin, which has a high affinity for oxygen. 6. They do not carry out any metabolism, so they do not utilize the oxygen being transported.
