What is the percentage of water in an adult. Water in the human body. structured water. Redox potential of water

Despite the fact that the human body consists of both water and solid materials, a much larger percentage belongs to liquids. According to physiologists, water is the most important component organism, specific gravity which reaches 70 percent. Consequently, in a body weighing 50 kilograms, the main part, i.e. 35 kilograms, belongs to the blood, lymphatic and extracellular fluids. And only 15 kilograms are occupied by organs, i.e. solid components. Moreover, this ratio body water content concerns adults. However, it is much higher in the early stages of life, especially during fetal development. The body of a newborn consists of 80 percent water, the body of a seven-month-old fetus is 85 percent, and a four-month-old fetus is 93 percent.

Three levels of fluid, and their ratio in the body

Internal body fluids do not mix. On the contrary, they are divided among themselves and distributed over different levels organism.

The first level of fluid is blood
The fluid closest to the surface of the body is blood. It is in the blood that substances from the outside are the first to enter - whether it be oxygen coming through the lungs, or nutrients coming from food. Blood occupies the upper compartment, accounting for 5 percent of body weight, and circulates through the veins, arteries, and capillaries that form the circulatory system.
Below is the level in which the extracellular fluid and lymph are located.

The second level of fluid - intercellular fluid and lymph
extracellular fluid, as the name implies, is located outside the cells. It surrounds them, filling the small spaces between them. Another name for this fluid is intercellular. It forms external environment for cells, a kind of ocean in which they "swim". This fluid receives oxygen (in liquid form) and nutrients delivered by the blood, and then transports them to the cells - the final processing points. The extracellular fluid receives processed products from the cells and transfers them to the upper compartment, to the bloodstream; it, in turn, delivers them to the excretory organs - the liver, kidneys, etc., which process these wastes and remove them from the body (see Water balance in the body)

Located on the same level as extracellular fluid, lymph removes some of the toxins from the cells and delivers them to the blood. It flows through the lymphatic vessels, flows into the bloodstream at the level of the clavicular arteries. Further, the toxins directly enter the excretory organs. Lymph and extracellular fluid form 15 percent of body weight, which is 3 times more than blood.

Third fluid level - intracellular fluid
Next level, third, deepest, he belongs intracellular fluid. She is educated by everyone. liquids located inside the cell. Despite the fact that the internal space of each cell is incredibly small, together they create an impressive volume. filling these cells intracellular fluid forms half the body weight. Oxygen and nutrients delivered to the cell by the extracellular fluid enter the intracellular fluid through the cell membrane. These substances are used by cell components (organelles) and the cell nucleus.

The body is made up of water
The body is primarily made up of water. For example, the heart and lungs are 70.9 percent water, muscles are 75 percent, the liver is 75.3 percent, and the spleen is 77 percent. Hence the average water content in the body - 75 percent. The brain is the organ with the most great content water - 83 percent. For normal functioning, it needs a sufficiently large amount of liquid. The brain gets 20 percent useful substances, carried by the blood, although in itself it makes up only 2 percent of the total body weight.

How can a watery body be solid?
So how is it that our body, which is almost water, looks so solid? With the exception of a few parts of the body (skin, nails), in which the concentration of solid components is quite high (78 percent is in the skeleton), the cells, paradoxically, appear solid due to the water with which they are filled. This phenomenon can be seen in the example of a common garden hose: it is soft and flexible when empty, but becomes rigid and hard as soon as it is filled with water. Water saturates the cells, presses on their walls, giving them a clear shape and elasticity.

Water in the human body

Water in the human body is involved in metabolic processes, nutrients and salts are dissolved in water. Chemical processes in cells are possible only in the presence of water.

The role of water in the human body. Water is the most important part of the human body. It is 65% of the weight of an adult, in children up to 80%.

If a person can live 30-40 days without food, then only 4-5 without water.

Importance of water for the human body. Water is involved in the regulation of body temperature: released with sweat, it evaporates and, cooling the body, protects it from overheating.

The need for water averages 2-2.5 liters per day. This need is satisfied approximately as follows: 1 liter in the form of a drink, 1 liter is contained in food, and 300-350 ml is formed in the body as a result of chemical transformations that occur in all cells and tissues.

Water is excreted from the body by the kidneys, sweat glands and lungs. The amount of water drunk and allocated is approximately the same. The need for water often depends on the quality and quantity of food, ambient temperature, etc.

A person should consume as much fluid as necessary to cover all of its consumption, otherwise dehydration of the body will occur and serious impairment of life will occur. Suffering from prolonged lack of water nervous system, appear mental disorders. Periods of complete apathy and drowsiness are replaced by visual and auditory hallucinations and convulsions. Violated the activity of vital nerve centers - respiratory and cardiovascular. If these phenomena increase, death may occur.

Healthy man should not limit oneself to drinking, but it is useful to drink little and often. Drinking a lot of liquid at once, as some beer or tea lovers do, is harmful - you can overload your heart; because all the liquid is absorbed into the blood, and until its excess is excreted by the kidneys, an excessive load is given to the heart.

Water is the basis of the human biological body, which contains 35–40 liters of intracellular and intercellular fluid. The cells of the body swim in the intercellular fluid, like fish in an aquarium. The greatest saturation with water in the tissues of the brain, liver, kidneys, lungs and glands. Water is the main lubricant in the joints. It also creates shock-absorbing water "pillows" in the intervertebral discs. Even bones are 20% water.

A person begins his life on Earth in the form of an embryo, which consists of 99% water. By the time of birth, water makes up 90% of his body. A child in childhood is more saturated with water, since the process of growth and cell division requires it in in large numbers. Therefore, children drink plenty of fluids. By the time a person reaches adulthood, the water content is reduced to 70%. If he dies in extreme old age, then by this time his body consists of water by about 50%.

About 5 liters of blood and about 2 liters of lymph flow through our arteries, veins and lymphatic vessels. We are a system of communicating vessels, through which flows of various fluids continuously move, interacting with each other. They are like rivers, which at times turn into stagnant swamps or become shallow - then stagnation and disease arise. And when the rivers accelerate again, everything falls into place. We feel the state of these rivers through our well-being.

All body functions depend on the rational movement of water in it. Her enough- this is the only way to provide access to water-borne elements ( nutrients, hormones, etc.) to the most important organs. A person can live without food for about a month, spending the body's accumulated reserves of nutrients, provided that he drinks water. And without water he will not live even a week, since the human body Not has reserves liquids capable of supporting its vital activity when there is no access to water sources.

However, there is a mechanism to help deal with periods of temporary water shortages. It prioritizes the blood supply to one or another part of the body by opening some capillaries and closing others. The order is predetermined according to the importance of the features. The brain, lungs, kidneys, liver and glands take precedence over muscles, bones and skin in the process of blood circulation. Maintaining a constant blood composition by the body due to fluctuations in the volume of water in some cells is a very delicate balancing mechanism. In the event of a lack of water, some cells have to do without ordinary norm, while others get just enough to keep the features.

The lack of water in the body is signaled by the feeling of thirst, the condition of the skin and the color of the urine. The color of urine in a person whose body does not receive enough water varies from dark yellow to orange. A well-hydrated body produces lighter-colored urine. The physiological norm of water consumption is 30–40 g per kilogram of live weight daily. This is approximately 6-8 glasses of water. You should drink enough water so that the urine becomes colorless.......

Need to drink water sips, several sips, fractionally, not in one gulp. With this method of drinking, water is very quickly absorbed into the intestines and disperses throughout the body. There is a "droplet" effect. The peculiarity of this effect is that even if a person is predisposed to edema, they do not occur. And habitual edema associated with cardiac or kidney failure usually disappear after a few days.

Chronic lack of water in the tissues is the cause of most diseases. Human body has no means of retaining excess water to create its stock. That's why we should drink water regularly, throughout the day.......

Cellular and intercellular fluid in living organisms has an extremely high degree of order, that is, it has the structure of ice. ensures the optimal course of redox reactions, the optimal level of metabolism and, consequently, the highest manifestation of the body's vital functions. If the body receives insufficiently structured water, then it has to spend its own energy on structuring ordinary water, which is so necessary for physiological processes.

In the body of a newborn baby, almost all water is structured. However, subsequently, with age, structured crystals become less and less. Due to the impact of pollutants, electromagnetic radiation and other harmful factors, crystal structures are damaged, diseases occur, aging of the body begins - first at the cellular level. By adulthood, the body may already contain from a quarter to a third of unstructured water.......

In the cells of our body there are small bodies -, - which are called "power stations". The processes of redox reactions take place in them, as a result of which the cell receives the energy necessary for all vital functions. But in the course of these reactions, free radicals- Negatively charged fragments of molecules. They are dangerous because, accumulating in the body, they trigger an avalanche of oxidative reactions. This process is similar to the appearance of rust on an iron product and causes accelerated cell aging. Therefore, it is extremely important that the internal environment of the body ensure the dominance restorative reactions.

One of the most significant factors in regulating the parameters of redox reactions is the redox potential (ORP) of this environment. The ORP of the internal environment of the human body normally always has a negative value......

ORP drinking water almost always positive, and this usually applies to all types of drinking water: both that flows from taps in all cities of the world, and that is sold in plastic bottles, and which is obtained after cleaning in most filter systems. The indicated difference in the ORP of the internal environment of the human body and drinking water means that ordinary water biologically Not compatible with the internal environment of the body, and the internal environment forced change redox properties of drinking water when used in metabolic processes, spending valuable cell energy to ensure biocompatibility. As a result, the biological structures of the body (cell membranes, cell organelles, nucleic acids, etc.) undergo constant energy weakening. The body gradually wears out, ages, the functions of vital organs become difficult. However, energy can be saved if used for drinking structured water with certain properties close to the properties of water in the body.......
