Detailed explanation-1: -Among micronutrients, calcium (Ca) and inorganic (i) phosphate (P) are the two main constituents of hydroxyapatite, the bone mineral that strengthens the mechanical resistance of the organic matrix. Bone contains about 99% and 80% of the body’s entire supply of Ca and P, respectively.
Detailed explanation-2: -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-3: -The mineral calcium helps your muscles, nerves, and cells work normally. 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.
Detailed explanation-5: -Phosphorus is the second most abundant mineral in the body, second to calcium. About 85% of the body’s phosphorus is stored in bones and teeth.
