Answer to Question 1

The bones serve as a repository of calcium that can be taken by or returned from the blood as needed. The blood calcium levels are held in a narrow range by the action of hormones. The body requires calcium for nerve function, muscle contraction, blood clotting, hormone secretion, and enzyme function. If the diet does not contain adequate calcium or vitamin D to keep the blood calcium levels in the necessary range, the bones will be required to release calcium to the blood. This will lead to further reduction in bone density.
