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 sickle cell anemia, red blood cells usually die about 10 times faster (after only 10 to 20 days). In such unhealthy conditions, the bone marrow that produces these red blood cells can't maintain the necessary replenishment rhythm.
In the red bone marrow.
Red blood cells because that is what carries oxygen throughout the body
Red Blood Cells
It has a substance in it called haegion which contains iron!!!
The four major components in blood are: -Plasma -Platelets -Red Blood Cells -White Blood Cells
long bones in our body are the resorviour of red blood cells. There from bone marrow stem cells the red blood cells diffrentiate
In the red bone marrow.
In case of the fetus, liver produces red blood cells. Red blood cells are produced by flat bones in case of adults. Given a challenge to produce the extra red blood cells, the liver may start producing red blood cells in adults also, as a last resort.
Red marrow found in the shafts of the long bones produce red blood cells. The humerus and femur are considered long bones.
Red blood cells are made in the bone marrow.
About 120 days
Red blood cells can not reproduce because they do not have a nucleus like all other cells. Red blood cells last at least 3-4 months. When they are destroyed, heme (consisting of iron) is released; the iron is used to reproduce red blood cells.
They last your whole life (not true) red blood cells: die and are made evry 3 weeks white blood cell: you never get more than you have brain cells: you can get any more (if you inhale carbon dinoxid some of the brain cells die, so do do it!)
Red blood cells are made in the red marrow of long bones. The marrow is in the central hollow of the shafts of these bones.
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.

Red and white blood cells are both made in the marrow of the long bones.
