Erythropoiesis occurs in which tissue?

Erythropoiesis—the production of red blood cells—occurs in red bone marrow, the myeloid tissue inside certain bones. In adults, this marrow is the primary site for forming erythroid cells from hematopoietic stem cells, under hormonal signals like erythropoietin. Lymph nodes mainly handle immune activation; the spleen helps filter blood and can contribute to blood cell production only in disease or under special conditions. The thymus is where T cells mature. So the normal site for erythropoiesis is red bone marrow.
