Bone marrow is the flexible tissue in the interior of bones. In humans, red blood cells are produced by cores of bone marrow in the heads of long bones in a process known as hematopoiesis.On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (143 lb), bone marrow typically accounts for approximately 2.6 kilograms (5.7 lb).he hematopoietic component of bone marrow produces approximately 500 billion blood cells per day, which use the bone marrow vasculature as a conduit to the body's systemic circulation. Bone marrow is also a key component of the lymphatic system, producing the lymphocytes that support the body's immune system.
The red blood cells are produced in the red bone marrow in the center of the bone. Marrow. Red blood cells, or erythrocytes, are made in the bone marrow as are white blood cel â¦ ls or leukocytes and they originate from stem cells.The production of red blood cells is also known as  hematopoiesis; this process occurs in the bone marrow. The  bone marrow is found in the spongy tissue in the middle of bones.  In this tissue there are pluripotent hematopoietic stem cells.
