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).
Oxygen is carried within red blood cells by a compound called hemoglobin, which is able to bind up to four oxygen molecules and form oxyhemoglobin. Each red blood cell contains large quantities of this molecule, allowing them to carry around far more oxygen than needed to ensure that supply always meets demand.
