The amount of water in the human body accounts for about a few percent of body weight

Humans, like other animals, contain a lot of water in their bodies, and the water content in an adult's body accounts for about 65% of a person's body weight. In the course of one's life, the amount of water in the body gradually decreases as people age. In infancy, the water content of the body can reach 72%, and by adulthood, the water content drops to about 65%.

It is worth noting that there are 8,200 ml of water in the body every day, which is secreted into the gastrointestinal tract (such as saliva, intestinal juice, pancreatic juice, etc.) by the oral cavity and gastrointestinal secretory glands, and the vast majority of this water (about 800 ml) is returned to the bloodstream from the ileum and colon**. As a result, patients with vomiting and diarrhoea are prone to losing water and becoming dehydrated.

Water in the human body is one of the main components of tissue cells, accounting for about 50% of a person's body weight. The rest of the water is in the blood and intercellular spaces, and a small amount of transfect water is present in the empty organs.

The body is about 65% of body weight. Among them, the cerebral marrow contains 75% water, the blood contains 83% water, the muscles contain 76% water, and even the hard bones contain 22% water! Without water, nutrients from food cannot be absorbed, waste products cannot be excreted from the body, and drugs cannot reach the site of action.

I remember reading the information before that it said that it was 90%...

I also forgot to say quite a lot anyway.

Adults account for about 60%-70% of their body weight, including 99% in the cerebrospinal cord, 94% in the lymph glands, 70% in the blood, 62% in the muscles, and 5% in the bones.

For example, the water content in bones and cartilage accounts for about 10% of the total amount of bones, and the water content in fat accounts for about 20% to 30% of the total amount of fat. The water contained in human muscles accounts for about 70% of the total muscles, especially the blood of the human body contains the most water, accounting for about 92% of the total blood.

Water makes up about 70% of the human body. Men have more water in their bodies than women, younger people have more water than older people, and newborns have about 70% to 75% of water in their bodies.

In the tissues of the human body, the content of water is also different: the water distributed in bones and cartilage accounts for about 10% of the total amount of bone; The water in the fat accounts for about 20% and 35% of the total fat rottenness; The distribution of water in the muscles has reached about 70% of the total muscle mass; In the plasma, except for 6% and 8% of plasma protein, about glucose and about about inorganic salts, the rest of the combustion content is all water, accounting for about 91% and 92% of the total plasma.

The human body is composed of four components: water, protein, fat, and inorganic matter, and its normal ratio is:

55% of body water, 20% of protein, 20% of body fat, and 5% of mineral.

The balance of body composition is the most basic condition for maintaining a healthy state.

Water in the human body can be divided into intracellular fluid and extra cellular-fluid. Under normal conditions, the ratio of intracellular fluid (ICF) to extracellular fluid (ECF) in the human body remains 2:1.

These body fluids, which make up 50 to 60% of body weight, are the largest components in the body, and act as carriers to provide nutrients and oxygen to the cells, and dissolve carbon dioxide and body waste in water to the organs of the body for chemical treatment. Body fluids maintain equilibrium in several ways, with intracellular 2 3 and extracellular 1 3, which is a very stable distribution.

However, if there is a problem with the metabolism, swelling or dehydration will occur, and the original water distribution will be unbalanced. In general, changes in the extracellular fluid are more pronounced when this phenomenon occurs. In other words, although the intracellular fluid increases when edema occurs, the increase in extracellular fluid is so large that the proportion of extracellular fluid in the total body fluid increases.

By the same token, the reduction in extracellular fluid during dehydration is much greater than that in intracellular fluid. This is due to the fact that intracellular fluid is more important from the point of view of life maintenance.

Various diseases can disrupt the normal distribution, which can increase the amount of extracellular fluid and cause edema. For example, patients with senile diseases and chronic diseases that cause muscle atrophy may not see edema on the surface, but the extracellular fluid in the human body will also increase relatively much, and nutrient deficiency edema may occur.

Water makes up about 70% of the human body. Men have more water in their bodies than women, younger people have more water than older people, and newborns have about 70% to 75% of water in their bodies. The amount of water in the tissues of the human body is also different:

Water distributed in bones and cartilage accounts for about 10% of the total amount of bone; Water in the fat accounts for about 20% and 35% of the total fat; The distribution of water in the muscles has reached about 70% of the total muscle mass; In the plasma, except for 6% and 8% plasma protein, about glucose and about about inorganic salts, the rest of the components are all water, accounting for about 91% 92% of the total plasma.

How much water does the human body consume every day? In general, the amount of water consumed per day in different ways is as follows:

Excrete about 400 ml of water through breathing;

Excrete water by ** about 400 800 ml;

about 150 ml of water is excreted through the feces;

about 1500 ml of water is excreted through urine;

The above totals 2500 ml.

However, the amount of water that can be obtained from food is about 800 ml per day, and when oxidizing nutrients are broken down in the body every day (in addition to producing energy, water is also produced) about 400 ml of water, the remaining 1300 ml of water must be replenished by diet (including drinks).

The amount of water that each person should drink per day is related to the person's age, weight, activity level, environment, temperature and other factors. In general, infants and young children need to drink 110 ml of water per day for every 1 kg of body weight; Children and adolescents need to drink 40 ml of water per day for every 1 kg of body weight; Adults need to drink 40 ml of water per day for every 1 kg of body weight. Therefore, an adult weighing 60 kg needs to drink about 2500 ml of water per day.

The body is about 60% of the body's water, and men have more water than women, and there is more water in the muscles.

Hello! The proportion of water in the human body is different at different times: in infancy, water accounts for 80%-90% of the human body; In adulthood, water makes up 75% of the human body; In old age, water makes up 65% of the human body. Hope it solves your doubts.

The human body water accounts for about 70 percent of body weight, young people account for a larger percentage than the elderly, and newborns account for about 70 to 75 percent of body weight.

Water is one of the very important substances involved in metabolism and an important part of the human body, water accounts for about 70% to 75% of the body's body weight, and the normal newborn has the most water in the body, accounting for about 80% of the total body weight.
