Bone marrow is a semi-solid Tissue found within the spongy (also known as cancellous) portions of Bones. In Birds and Mammals, bone marrow is the primary site of new BloodCell production (or haematopoiesis). It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells. In adult Humans, bone marrow is primarily located in the Ribs, Vertebrae, Sternum, and bones of the Pelvis. Bone marrow comprises approximately 5% of total body mass in healthy adult humans, such that a man weighing 73 kg (161 lbs) will have around 3.7 kg (8 lbs) of bone marrow. [from Wikipedia].
