Red blood cells. Cutaway computer illustration of red blood cells (erythrocytes,round,red) inside a blood vessel. 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. The cell's interior is packed with haemoglobin,a red iron-containing pigment that has an oxygen-carrying capacity. The main function of red blood cells is to distribute oxygen to body tissues and to carry waste carbon dioxide back to the lungs | |
