How are red blood cells released into the bloodstream?

Production of red blood cells is controlled by erythropoietin, a hormone produced primarily by the kidneys. Red blood cells start as immature cells in the bone marrow and after approximately seven days of maturation are released into the bloodstream.

Similarly, it is asked, how red blood cells are destroyed?

The hemoglobin is the part of the erythrocyte that actually carries the oxygen and carbon dioxide. As red blood cells wear out in the bloodstream, they are taken in by the spleen, an organ on the left side of the abdomen below the stomach, and destroyed. Parts of the old cells are salvaged to make new red blood cells.
