钙,人们称为生命元素。它是人体中含量最多的矿物质元素,约占体重的2％,总量可达1200克,其中99％集中于骨骼和牙齿,其余的存在于软组织、细胞外液和血液中。钙除维持骨骼动态平衡外,还参与了整个生命的新陈代谢。人体内每个细胞的功能,都离不开钙。如果没有钙的参与,神经细胞就不能传导冲动,肌肉就不能收缩,心脏就不能搏动,肾脏就不能排泄
Calcium, known as the element of life. It is the most abundant mineral element in the human body, accounting for about 2% of body weight, with a total amount of up to 1200 grams, 99% of which are concentrated in bones and teeth and the rest in soft tissue, extracellular fluid and blood. Calcium in addition to maintain the dynamic balance of bones, but also involved in the metabolism of the entire life. The function of each cell in the human body is inseparable from calcium. Without the involvement of calcium, nerve cells can not transmit impulses, muscles can not shrink, the heart can not beat, the kidneys can not be excreted
