The cancellous part of the bone contains bone marrow. It produces blood cells including red blood cells, platelets and white blood cells. This process is called as hematopoiesis.

The bone tissue regulates acid-base balance, stores calcium, and fat cells.  It acts as an endocrine organ by controlling the phosphate metabolism. It release fibroblast growth factor – 23 (FGF-23), which acts on kidneys to reduce phosphate reabsorption. The bone cells also release a hormone called osteocalcin. This contributes to the regulation of blood sugar (glucose) and fat deposition. Osteocalcin increases both insulin secretion and sensitivity, in addition to boosting the number of insulin-producing cells and reducing stores of fat.
