  • Bird red blood cells collected from a Baltimore Oriole (Icterus galbula).  Colored scanning electron micrograph (SEM) of red blood cells (erythrocytes, red) from avian tissue. These cells contain hemoglobin, 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. Magnificationof image is 1960x and the image is  80um  wide. .
