It keeps the water at levels, ions such as potassium sodium calcium magnesium and phosphate, pH and blood pressure as close to constant as possible.

它使水和离子如钾钠钙镁和磷酸盐，pH 值和血压尽可能接近恒定。

Calcium, magnesium, and phosphorus harden bones and teeth, while iron is, of course, crucial in hemoglobin. Plus, potassium, sodium, and chlorine help maintain your body's pH balance and are used in action potentials.

钙、镁和磷使骨骼和牙齿变硬，而铁当然对血红蛋白至关重要。此外，钾、钠和氯有助于维持身体的酸碱度平衡，并用于动作电位。
