Ninety-nine percentage is calcium in the bone. Calcium plays an important role in the muscle contraction. Phosphate and calcium exchange between the bone and the blood. The bone has two types of cells called osteoblasts which form the tissue and osteoclasts which resorbs the salt out of the bone and dissolved it in the blood. If the calcium level drops, parathyroid hormone is secreted. The hormone is separated into three different sites in the body to raise the blood level calcium to normal. The increase of calcium prevents the

When too much parathormone are released it raises the calcium level more than normal a condition is developing called hypercalcemia. As the calcium level raises the phosphate level drops. With the loss of calcium the bones are weaken. Tumors and cysts can develop in the bones. Excessive calcium develops kidney stones. Excessive calcium also can cause complications which are pain in the bone, muscles loss their tone and weaken, and heart rate slows.
