What percent of the human body is water, and what percentage of water is the human body?

If the proportion of water in the human body is compared with the structure of the word "human", water should be a handful, and other nutrients are a handful, and with the mutual support of hydration and other nutrients, there is life.

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;

Drain 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.

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.

70 percent of water, most of which is water in the human body, accounts for about this proportion.

205.Which organ has the most water in the human body, come and popularize science.

70% If it's a woman, it's probably more, after all, women are made of water o( o haha.

Judging from the weight of the person, most of the human body is made of water. Water makes up 70% of the body's weight, and babies have up to 80% of their body water. The water content of the human blood accounts for 83%, and the water accounts for 76% of the muscles; 80% in the heart and lungs; 83% in the kidneys; 68% in the liver; 75% in the brain.

Even bones that appear to be strong have more than 20% water. This saltwater sea in the human body is the underwater environment brought about by the first organism when it crawled out of the warm ocean that gave birth to life 500 million years ago and walked onto land.

Water is the first element of human life. It is the first of the seven major nutrients (water, protein, fat, carbohydrates, minerals, vitamins, and fiber) of the human body. Water is also the best solvent, it carries many, many dissolved or suspended valuable chemicals in the human body, nourishing the physiology of the human body.

This sea of salt water in the human body flows through all the blood vessels and no matter how subtle the pipes in the human body, impacting every cell wall and filling every cell, and no part of the human body can survive without it.

Water maintains the concentration of human tissues such as blood and drenching fluid, and promotes their normal circulation. Water in the human body flows in, flows through and out like the streams and tides of nature. Normally, the human body excretes litres of water every day and consumes the same amount to maintain homeostasis.

People drink about 1/2 litres of water a day, and the other 1 litre of water they need comes from food. The amount of water excreted every day is about 1 and a half liters of urine, and the other 1 liter of water is evaporated from sweat and breath (through ** and lungs) to keep the body cool, and about 100ml of water is excreted in the feces.

Water assists and excretes the body's waste. The human body produces about 11 liters of water every day, of which 1 liter is supplied by the salivary glands to moisten the mouth and activate the digestive system. The stomach produces 1 and a half liters of digestive juices, and the pancreas, liver, and intestines produce about 5 liters of water.

When all of this fluid flows through the small intestine, if it is not reabsorbed, it is excreted in semi-solid stool when it finally reaches the large intestine, or it is returned to the body through the intestinal wall.

Water dissipates heat and regulates body temperature. Chemical activity is everywhere in the human body, and the heat generated by muscle activity when we do physical work or sports is enough to burn us off. However, the water that infiltrates and penetrates the tissues of the cells can immediately absorb the excess enthusiasm.

Water in the body is also a shock absorber, surrounding our brain, protecting from **.

In the general human body: water accounts for about 70%, because the human body is composed of cells, and the cytoplasmic matrix of each cell is water, so it can be said that 70% of the human body is water.

82% of the blood is buried in the water hall, the outer epidermis of the dermis contains about 60% of the water, and the stratum corneum contains about 15% to 20% of the water

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.

The proportion of water in the human body should be about 60 70%, but the proportion of water in people of different ages is different, if it is the neonatal period, the proportion of water can be as high as 90%, water plays a great role in the human body, is an important component of extracellular fluid and blood, and at the same time, sweat and urine in the human body can also be excreted through water.

Water makes up 70 percent of the human body.
