Erythrocyte survival and lifespan measurements obtained with transfused erythrocytes are in good accordance with those obtained using metabolic labeling studies indicating an overall good survival with a maximum of 135 days after transfusion Mollison et al 1987. Red blood cells or erythrocytes give blood its distinctive color and make up about 40-45 of bloods volume.

Red blood cells have a limited lifespan because they dont have a center membrane nucleus. This is an extremely efficient process as macrophages phagocytose about 5 million erythrocytes every second without any significant release of hemoglobin in the circulation.

In humans and some other species RBC normally survive in a nonrandom manner. A unit of red blood cells RBCs expires in 35 or 42 days because of the type of anticoagulant in the bag. Those cells arent dividing but theyre still genetically normal and alive at least until they pick up enough damage to kill them.
