Practice questions on Erythropoiesis
The major site of erythrocyte production (erythropoiesis) in humans after birth is the:
- Bone marrow
- Spleen
- Liver
- Lymph nodes
Answer: A. In adults, the bone marrow, particularly the red marrow of flat bones and the epiphyses of long bones, is the primary site of red blood cell production.
In adult humans, the major physiological site of erythrocyte production (erythropoiesis) is which of the following?
- Spleen
- Liver
- Kidney
- Bone marrow
Answer: D. In adults, the red bone marrow is the primary site of hematopoiesis, including the production of erythrocytes. The liver and spleen can be sites of extramedullary hematopoiesis under certain pathological conditions.
In a healthy adult, what is the major site of erythrocyte production (erythropoiesis)?
- Yolk sac
- Liver
- Spleen
- Red bone marrow
Answer: D. In adults, erythropoiesis occurs almost exclusively in the red bone marrow of flat and long bones.
In healthy adults, the major site of erythrocyte production (erythropoiesis) is the:
- Liver
- Spleen
- Red bone marrow
- Thymus
Answer: C. While the liver/spleen produce RBCs in the fetus, the bone marrow takes over as the primary site after birth.
