how long does a red blood cell live
Normal (i.e. healthy) red bloods cells live about 120 days in the bloodstream, after which they die and are replaced by new ones. In some unhealthy conditions, for example in â¦ sickle cell anemia, red blood cells usually die about 10 times faster (after only 10 to 20 days).aking the world better, one answer at a time. Red blood cells last an average of 120 days in the bloodstream. When red blood cells age, they are removed by macrophages in the liver and spleen.
