Exchange Water

Water metabolism is a type of metabolism that includes the processes of intake, transformation in the body and excretion of water.

Water is an essential component of the body and plays a key role in maintaining homeostasis. A constant influx and outflow of water is necessary for the normal functioning of all body systems.

Water enters the body with food and drink. The bulk of the water is absorbed in the small intestine and enters the circulatory system. From the blood, water is distributed to all tissues and organs.

In the body, water performs many functions: it is a solvent and transport medium for nutrients, metabolic products, hormones and other biologically active compounds; participates in thermoregulation; part of cells and intercellular fluid; necessary for many biochemical reactions.

Excess water is eliminated from the body through urine, sweat, and breathing. Disturbances in water balance lead to the development of edema or dehydration, which is dangerous to health. Therefore, water metabolism is carefully regulated by the kidneys, hypothalamus and hormonal system. Maintaining optimal water balance is the most important condition for homeostasis and normal functioning of the body.

Water exchange

Water metabolism (water-salt balance) Water metabolism is a type of metabolism that includes the intake, transformation and release of water from the body. The body loses most of the water involved in all physiological processes through the kidneys in the form of primary urine, which contains 80-95% sodium and potassium, as well as chlorides and sulfates (other substances make up no more than 4%) . Thus, the concentration of salts in the blood and urine is approximately the same (about 0.9% sodium). Most of the salts are excreted in urine and feces (lye

**Water-salt metabolism** (WMS) reflects all the processes occurring in the body with its water and salt components and characterizes one of the many types of metabolism, united by the concept of “metabolic processes”.

In the process of evolution, organisms have developed a water-electrolyte metabolism, which represents
