Red blood cells. Coloured scanning electron micrograph (SEM) of a section through a freeze- fractured blood vessel,showing human red blood cells (erythrocytes,red). These biconcave,disc-shaped cells transport oxygen from the lungs to body cells. They also remove carbon dioxide to the lungs for exhalation. Their red colour comes from the oxygen-carrying protein haemoglobin. Red blood cells are the most abundant cell in the blood. The endothelial lining of the blood vessel (pink) is also seen.
