ANATOMY

Detailed explanation-1: -The shape or structure of bone is at least as important as its mass in providing this strength. The skeleton is also a storehouse for two minerals, calcium and phosphorus, that are essential for the functioning of other body systems, and this storehouse must be called upon in times of need.

Detailed explanation-2: -The skeleton serves two major functions at the same time: A structural function – Strong bones support and protect our body and allow us to move about on dry land. A reservoir function – Bones contain large amounts of calcium and phosphorus and thus provide a reserve supply for these minerals.

Detailed explanation-3: -Your body also needs calcium (as well as phosphorus) to make healthy bones. Bones are the main storage site of calcium in the body.

Detailed explanation-4: -About 99% of the body’s calcium is stored in bones, and the remaining 1% is found in blood, muscle, and other tissues. In order to perform these vital daily functions, the body works to keep a steady amount of calcium in the blood and tissues.

Detailed explanation-5: -Bone composition and structure The major minerals found in bone are calcium and phosphorus in the form of an insoluble salt called hydroxyapatite [chemical formula: (Ca)10(PO4)6(OH)2].
