Bird red blood cells. Coloured scanning electron micrograph (SEM) of red blood cells (erythrocytes,orange) in avian heart tissue (purple). These cells contain haemoglobin,a pigment that allows these cells to carry oxygen around the body. Non- mammalian red blood cells (such as avian ones) are oval in shape and contain a cell nucleus (not seen). Human red blood cells are disc-shaped and do not have a cell nucleus | |
