Question

where does the process of hematopoiesis occur in the adult?
a red bone marrow
b yellow bone marrow
c liver
d spleen

Explanation:

Hematopoiesis is the process of blood cell formation. In adults, red bone marrow is the primary site for this process. Yellow bone marrow is mainly composed of fat cells and does not actively participate in hematopoiesis in normal adult conditions. The liver and spleen are sites of hematopoiesis during fetal development but not in adults (except in some pathological conditions like extramedullary hematopoiesis which is not the normal case).

Answer:

A. Red bone marrow
