Water-salt exchange

Description

Study of water and mineral metabolism

Water-mineral exchange includes the processes of entry, absorption, distribution and release of water and salts from the body.

The role of salts and individual chemical elements is quite important. As a plastic material, they are part of various body tissues (bones, muscles, skin), are components of many proteins and nucleic acids that are in a free state. They are necessary for the process of metabolism, as activators and co-enzymes of many enzymes. 70 chemical elements are found in the human body, of which 47 chemical elements are permanent and are called biogenic. Depending on the amount of content of biogenic chemical elements, they are divided into macro-, micro- and ultra-microelements. Macroelements include elements with a concentration in the body of more than 0.001% (Na, K, Ca. P, СL, S).

Water-mineral exchange ensures the constancy of the ionic composition, acid-base balance, volume of fluids in the body's internal environment, osmotic pressure, that is, the main parameters of homeostasis.
