钠、钾两元素,在人体内是以离子形式存在的,一个在细胞外,一个在细胞内,它们配合默契,共同调整细胞与血液之间的容量、渗透压和酸碱平衡,对维持细胞的正常结构和功能起着非常重要的作用。当肌肉收缩或冲动时,两种元素便迅速透过细胞膜进行交换,交换结果便产生了电脉冲,可以控制 Sodium and potassium two elements, in the form of ions exist in the body, one in the cell, one in the cell, they work together to adjust the capacity between cells and blood, osmotic pressure and acid-base balance, the maintenance of cells The normal structure and function play a very important role. When muscle contraction or impulse, the two elements will be rapidly exchanged through the cell membrane, the exchange results will have an electrical pulse, you can control
