the cancellous part of bones contain bone marrow. bone marrow produces blood cells in a process called hematopoiesis. blood cells that are created in bone marrow include red blood cells, platelets and white blood cells. progenitor cells such as the hematopoietic stem cell divide in a process called mitosis to produce precursor cells. these include precursors which eventually give rise to white blood cells, and erythroblasts which give rise to red blood cells. unlike red and white blood cells, created by mitosis, platelets are shed from very large cells called megakaryocytes. this process of progressive differentiation occurs within the bone marrow. after the cells are matured, they enter the circulation. every day, over 2.5 billion red blood cells and platelets, and 50–100 billion granulocytes are produced in this way.
