The diffusion is the transport of molecules. The molecules are transported from a region of higher concentration to lower concentration. The change in the volume of red blood cells occurs by the process of diffusion.
The RBCs carry oxygen and it is involved in transfer of oxygen from lungs.During the time of respiration in cell, a decline in level of oxygen and glucose occurs inside RBCs. The process of diffusion allows the movement of oxygen and glucose into RBCs.
The process that is most likely involved in the change in red blood cell volume would be diffusion. <span>When a cell is respiring the concentration of oxygen and glucose inside the cell is lower than the surrounding </span>blood<span> so these substances move into the cell. Hope this answers the question.</span>
