∙ 2012-06-25 15:09:37Blood 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

the bone marrow is located inside the bone. if you have ever taken a look at a bone (even animal bones) they have they tiny little holes in them. these holes transport the new blood from the bone marrow into the blood stream. i held a femur bone of a deer (i think it was a deer) it had only a few or couple of holes in it to allow blood from the bone marrow.
