red blood cell
n. Abbr. RBC
A cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues. In mammals, the red blood cell is disk-shaped and biconcave, contains hemoglobin, and lacks a nucleus. Also called erythrocyte, red cell, red corpuscle.

red blood cell(rĕd)
Any of the disc-shaped cells that circulate in the blood of vertebrate animals, contain hemoglobin, and give blood its red color. The hemoglobin binds to oxygen, which is then transported by the cells to all of the tissues of the body. The red blood cells of mammals have no nucleus. Red blood cells are formed in the bone marrow. Also called erythrocyte. See more at cell.
Did You Know? Blood contains many cell types, but the distinctive red color comes from the aptly named red blood cells (RBCs). RBCs have their rich red color because of a vitally important iron-containing protein called hemoglobin. The protein picks up oxygen molecules as the blood exchanges gases in the lungs. The RBCs then carry oxygen to the far reaches of the body, where it is released for use by other cells, such as those of the brain and muscles. Just as importantly, after the RBC drops off its load of oxygen, its hemoglobin picks up carbon dioxide, the waste product of those brain and muscle cells, and brings it back to the lungs to be breathed out. All animals have some oxygen distribution system, but only vertebrate animals use RBCs. In some invertebrate animals, such as the earthworm, oxygen is transported using hemoglobin that is freely dissolved in the blood. Other invertebrates don't use hemoglobin at all. The horseshoe crab, for instance, uses copper instead of iron, making its blood blue instead of red.
