Best Answer

Blood cells are made in the bone marrow. Erythrocytes, or red blood cells, are constantly being produced and released from marrow tissue. Leukocytes, or white blood cells are also produced in the bone marrow. B cells and T cells are leukocytes that are made and mature in the bone marrow while T cells mature in Thymus.

In the Fetus

During embryonic development, blood is first formed extra-embryonically and production gradually shifts into the spleen and fetal liver, before finally occurring primarily in the bone marrow.
