Bird red blood cells. Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes,red) from avian tissue. These cells contain haemoglobin,a pigment that allows them to carry oxygen around the body. Non-mammalian red blood cells (such as these) are oval (discoid) in shape and contain a cell nucleus. Human red blood cells are disc-shaped and do not have a cell nucleus. Magnification: x1500 when printed 10 centimetres wide | |
