Erythropoiesis comes from the Greek word 'Erythro' meaning 'red' and 'poiesis' meaning 'to make'.
It is a process that produces red blood cells. It is stimulated by decreased oxygen in circulation and is detected by the kidneys, which then secrete the hormone 'erythropoietin'. This hormone stimulates the red blood cell precursors., which then activates the production of red blood cells in hemopoietic tissues in the bone marrow. Thus, the correct answer is Red bone marrow.
