During fetal development the bones of the fetus are composed of cartilage tissue. As the embryo develops the process of depositing calcium salts in the soft, cartilaginous bones occurs and continues throughout the life of the individual after birth. The gradual replacement of cartilage and its intercellular substance by immature bone cells and calcium deposits is called ossification (bone formation). The formation of bone is dependent to a great extent on a proper supply of calcium and phosphorus to the bone tissue. These minerals must be taken into the body along with a sufficient amount of vitamin D.
