What is the ratio of water to blood in the body

Is it a coincidence that 75% of the human body is water and 75% of the earth's surface is water? Each organ of the human body is extremely rich in water, 83% of the water in the blood and kidneys, 80% in the heart, 76% in the muscles, 75% in the brain, 68% in the liver, and 22% in the bones.

Life is made up of cells, and cells must be "soaked in water" to survive. Dryness is the main manifestation of aging. Young people account for 42% of intracellular water, while older people account for only 33%, resulting in wrinkles and gradual shrinkage of subcutaneous tissues.

The process of aging is the process of losing moisture. People can go without meals for a few days, but they can't go a day without drinking water, and if the human body loses 15%-20% of its body weight, its physiological functions will stop, and then it will die.

Nearly 70% of the human body is water. That is, if a person weighs 60 kilograms, the water accounts for more than 40 kilograms. In the case of infants, it is more than 80%, and the proportion of fetal fluid that is still in the mother's body is even higher. The water content of the elderly is only 50%-60%.

Judging from the weight of human repentance, most of the human body is made of water. Water makes up 70% of the body's weight, and babies have 80% water in their bodiesThe water content in the human blood accounts for 83% of the afterglow, and the water accounts for 76% in 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 of the human body (water, protein, fat, positive carbohydrates, minerals, vitamins, and fiber). 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.

The amount of blood in the human body is about 7 8 of body weight, if the weight is 60 kg, the blood volume is about 4200 4800 ml. Blood vessel rupture caused by various causes can lead to bleeding, and if the amount of blood loss is small, not more than 10 of the total blood volume, it can be recovered quickly through the body's self-regulation; If the amount of blood loss is large, reaching 20 of the total blood volume, symptoms such as rapid pulse and decreased blood pressure will appear; If 30% or more of the body's blood is lost in a short period of time, it can be life-threatening.

Blood is made up of four components: plasma, red blood cells, white blood cells, and platelets. Plasma makes up about 55% of blood and is a mixture of water, sugar, fat, protein, potassium and calcium salts. Blood cells make up the other 45% of the blood.

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;

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.
