Document Summary

Chapter summary: bones are organs that contain metabolically active tissues composed primarily of minerals and a fibrous protein called collagen. The three types of bone activity are growth, modeling, and remodeling. Bone density can be measured by dual energy x-ray absorptiometry. Calcium is a mineral that plays a major role in providing structure to bones and teeth. Blood calcium is maintained within a very narrow range. Bone calcium is used to maintain normal blood calcium when necessary. Calcium is also necessary for nerve and muscle function, healthy blood pressure, and blood clotting. Vitamin d is a fat-soluble vitamin and hormone. It regulates blood calcium levels and maintains bone health. Vitamin k is a fat-soluble vitamin and coenzyme that is important for blood clotting and bone metabolism. Phosphorus is the major negatively charged electrolyte inside the cell. It helps to maintain fluid balance and bone health.
