一、钙在人体代谢中的重要性 钙是体内含最最多的元素之一,它不仅是骨骼、组织的重要构成物,而且在机体生长发育过程中起着重要的作用。 钙的主要功能:体内99％的钙是构成骨骼和牙齿以及维持骨骼,其余1％的钙调节下列极其重要的生理功能: (1)肌肉的收缩与舒张:钙对肌肉的收缩与舒张,以及心脏的收缩与舒张中均起特别重要的作用。 (2)帮助血液凝固:钙是凝血的重要因子之一,如血液中缺少钙则损伤后易出血不止。
First, the importance of calcium in human metabolism Calcium is one of the most abundant elements in the body, which is not only an important component of bone and tissue, but also plays an important role in the growth and development of the body. The main function of calcium: the body of 99% of the calcium is the formation of bone and teeth and maintain the bones, the remaining 1% of the calcium regulation of the following important physiological functions: (1) muscle contraction and relaxation: calcium contraction and relaxation of muscle, and Heart contraction and relaxation play a particularly important role. (2) to help blood coagulation: Calcium is one of the important factors of coagulation, such as the lack of calcium in the blood is more likely to bleeding after injury.
