What happens when a red blood cell dies?
When red cells die, hemoglobin is broken up: iron is salvaged, transported to the bone marrow by proteins called transferrins, and used again in the production of new red blood cells; the remainder of the hemoglobin forms the basis of bilirubin, a chemical that is excreted into the bile and gives the feces their …

How do you treat high red blood cell count?

The famous statistic, “our body fully replaces itself every seven years,” probably came in part from studies that look at the average age of a cell in humans.
