Red blood cells. Coloured transmission electron micrograph (TEM) of red blood cells (erythrocytes) in various different orientations. Red blood cells are biconcave,giving them a large surface area for gas exchange,and highly elastic,enabling them to pass through narrow capillary vessels. They have no nucleus,but their interior is packed with haemoglobin. Haemoglobin is a red iron-containing pigment that enables these cells to carry oxygen to body tissues and to transport waste carbon dioxide back to the lungs.
