Red blood cells. Computer-enhanced scanning electron micrograph (SEM) of human red blood cells (erythrocytes). 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.
