Red blood cell: The blood cell that carries oxygen. Red cells contain hemoglobin and it is the hemoglobin which permits them to transport oxygen (and carbon dioxide). Hemoglobin, aside from being a transport molecule, is a pigment. It gives the cell its red color (and name).
The main function of red blood cells is the transport of oxygen from the lungs to the body's cells. Red blood cells contain a protein called hemoglobin that actually carries that oxygen.
