What Do Red Blood Cells Do?

5. Production
Our red blood cells are manufactured in our bone marrow. They take approximately 7 days to reach full maturity before they are then released into the blood supply. Once released into the blood stream, red blood cells have a life of approximately 120 days.
One thing that differentiates red blood cells from many other types of cell is that it has no nucleus. This helps to make the cells flexible, allowing them to pass through even the narrowest of blood vessels. This leads to some tight squeezes that can damage the cell’s membranes, limiting how long they are able to live.
