Light micrograph of human red blood cells (erythrocytes),the principal function of which is to circulate oxygen around the body to the organs & tissues. They are biconcave in shape,an adaption for maximum surface area over which the exchange of gases may take place. Erythroytes also have enormous elasticity & ability to deform that enables them to pass through the narrow capillary vessels. The interior of the cell is packed with haemoglobin,a red iron- containing pigment which has a good oxygen carrying capacity. The nucleus & other organelles are lost as the cell matures.
