The bloodstream is made up of multiple blood cell types. Red and white blood cells are responsible for many functions. The former transport oxygen and carbon dioxide in the body, while the latter help fight infections and encourage clotting. The bone marrow is the creation site of all of these blood cells. Reticulocytes are also created in the bone marrow and serve an essential function: creating and maintaining red blood cells.
Reticulocytes are immature red blood cells that have one more step to complete before they become full-fledged cells. The name comes from their reticular or mesh-like appearance when viewed through a microscope. The mesh is composed of nucleus strands waiting for export from the cell.
