Red blood cell. Coloured scanning electron micrograph (SEM) of a red blood cell. This disc- shaped cell,also known as an erythrocyte,transports oxygen from the lungs to the tissues during respiration. It contains large amounts of haemoglobin,a pigmented protein which binds oxygen. It is one of several types of blood cell,all of which develop from stem cells in the bone marrow. The formation of a red blood cell is known as erythropoiesis and takes about five days. Magnification: 11,200 at 6x7cm size | |
