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.
Bone marrow is soft, gelatinous tissue that fills the medullary cavities-the centers of bones. There are two types of bone marrow: red bone marrow (also known as myeloid tissue) and yellow bone marrow (fatty tissue). 200 billion new blood cells are made by the bone marrow every day. 2  Healthy bone marrow manufactures between 150,000 and 450,000 platelets per microliter of blood, the amount of blood that fits on the head of a pin. 3  Bone marrow contains mesenchymal and hematopoietic stem cells.
