在人体中有宏量元素11种,包括碳、氢、氧、氮、钙、磷、镁、钠、钾、硫、氯,它们占人体元素总量的99.9%。其中,与骨的代谢有重要关系的有钙、磷、镁。钙为人体总量的2%,人体内的钙99%在骨骼中。磷占体重的1%,体内的磷80%在骨和牙中。镁占体重的0.05%,60%存在于骨中。当身体缺少钙、磷、镁等元素时,骨骼即会疏松变脆。 在人体内除上述宏量元素外,还有41种微量元素,占人体元素的0.05%。其中14～15种为必需微量元素,虽然数量极微,但其作用极为
In the human body there are 11 macro elements, including carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, potassium, sulfur, chlorine, which accounts for 99.9% of the total human element. Among them, the metabolism of bone has an important relationship with calcium, phosphorus, magnesium. Calcium is 2% of the total human body and 99% of the body’s calcium is in the bone. Phosphorus accounts for 1% of body weight and 80% of body phosphorus is in bone and teeth. Magnesium accounts for 0.05% of body weight and 60% exists in bone. When the body lacks calcium, phosphorus, magnesium and other elements, the bone will become loose and brittle. In addition to the above macro elements in the human body, there are 41 trace elements, accounting for 0.05% of human elements. Of which 14 to 15 kinds of essential trace elements, although the number is minimal, but its role is extremely
