Extended data

Inorganic salts are very important to the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, while soft tissues contain more potassium. Inorganic salt ions in body fluids regulate the permeability of cell membrane, control water, maintain normal osmotic pressure and acid-base balance, help transport common elements to the whole body, and participate in nerve activity and muscle contraction.

Due to metabolism, a certain amount of inorganic salts are excreted from various channels every day, so they must be supplemented by diet. The metabolism of inorganic salts can be judged by analyzing the concentration in blood, hair, urine or tissues. The functions of inorganic salts are interrelated in human body. In a suitable concentration range, it is beneficial to the health of people, animals and plants. Lack or excess can cause diseases, and diseases affect their metabolism and often increase their consumption.
