Name the sites of hematopoiesis, including erythropoiesis, from early embryonic stage of development until fully established in adults.
Understand the Problem
The question is asking for the specific locations where hematopoiesis, including erythropoiesis, occurs during different stages of embryonic development and into adulthood. It aims to identify the progression of these sites from early development to adult stages.
Answer
Yolk sac, fetal liver and spleen, then bone marrow.
The sites of hematopoiesis, including erythropoiesis, transition as follows: 1. Yolk sac in the early embryo, 2. Liver and spleen during fetal development, 3. Bone marrow becoming the main site in late fetal development and continuing into adulthood.
Answer for screen readers
The sites of hematopoiesis, including erythropoiesis, transition as follows: 1. Yolk sac in the early embryo, 2. Liver and spleen during fetal development, 3. Bone marrow becoming the main site in late fetal development and continuing into adulthood.
More Information
Initially in embryonic development, hematopoiesis is primitive, producing nucleated erythrocytes. The liver soon becomes a major hematopoietic organ until bone marrow matures, establishing itself as the primary site for blood cell production.
Tips
Common mistakes include confusing the stages and sites of hematopoiesis or overlooking the temporary role of the fetal liver and spleen.
