This question is very professional and may not be understood by many people. Now I will try to explain the relationship between human kidney and body in plain language, and then talk about how much water to drink.

First of all, clarify some misunderstandings about the kidney.

First of all, what are the so-called rumors in the Jianghu? Kidney deficiency? This? Kidney deficiency? By no means refers to kidney deficiency, those charlatans simply don't know what kidney is. Kidney deficiency? This is just a universal plaster for their cheating, and whoever is labeled will be unlucky. Did they say that? Kidney deficiency? In Chinese, renal function refers more to sexual function. Their? Kidney? Mainly refers to men's balls, so they say? Kidney deficiency? Yes, I will, okay? Tonifying kidney and strengthening yang? . Women also have kidneys, but? Kidney deficiency? Will never appear in women, which means. Kidney? Not the other kidney.

Secondly, the kidney is the filter of the human body. Although this filter is very important to the human body, it will kill people if it is broken, but it has nothing to do with the so-called sexual function. There is something wrong with kidney function, which is not traditional? Kidney deficiency? . Therefore, if there is something wrong with the kidney, you must go to a regular hospital for treatment, never? Kidney deficiency? I was cheated, and I ended up with both money and people.

Third, many people call it kidney? Waist? It is wrong to think that kidneys grow on both sides of the waist. The actual position of the kidney is located on both sides of the posterior spine, and the two kidneys are not at the same height. The left kidney is higher than the right kidney 1~2cm. The left kidney faces the transverse process of the first lumbar vertebra and the right kidney faces the transverse process of the second lumbar vertebra. Therefore, sometimes there is a cramp-like pain in the back, so we should consider kidney diseases such as kidney calculi and seek medical advice in time.

Now let's talk about renal function.

Simply put, the function of the kidney is a filter, which produces urine through filtration and excretes the filtered waste toxin garbage with the urine. The human body should eat and drink water every day to replenish energy, which will be absorbed by the blood and flow all over the body to keep people alive. In the process of systemic circulation, blood not only brings nutrition to every organ, but also discharges some wastes, rubbish and toxins. After the blood flows through the kidney and is filtered, the waste, garbage and toxins are discharged with the urine, and the nutritious fresh blood returns to the whole body again.

Renal anatomy has clearly explained the mechanism of kidney action. The kidney is mainly composed of glomerulus, renal capsule, renal tubule, renal interstitium, blood vessels and nerves. The kidney has millions of nephrons, namely glomeruli and renal tubules. When blood flows through the glomerulus, it is formed by preliminary filtration. Original urine? After being reabsorbed by renal tubules, choose to leave useful things and water, turn into new blood and flow back into the body, following unwanted things? Finally pee? Stored in the renal pelvis.

The renal pelvis can only hold 3 ~ 7 ml of urine. When it is full, it will be squeezed out and reach the bladder through the ureter. The bladder can store about 400ml of urine. When the urine in the bladder reaches 250~300ml, urination will occur. When it is close to 400ml, there will be a strong sense of urine; The warning value of holding back urine is generally 800ml, and there are two consequences when holding back to the limit: urinating pants or hurting the body. If there is something wrong with the micturition system, when the urine accumulates to 1000ml, it will lead to bladder rupture.

The kidneys are very tired every day, so take good care of them.

The blood flowing through the kidney reaches about 180L every day. What is this concept? That's an 8L barrel of water, 22 and a half barrels! How much blood does the human body have, accounting for about 7-8% of the total body weight, which is about 5L. Therefore, the kidney should filter human blood more than 30 times a day to ensure the vitality of the human body. It can be seen how important the kidney is to the human body and must be protected.

How to protect it? Just don't eat casually. Here, I want to remind people with traditional health care complex. Among many traditional health preserving methods, especially some so-called traditions? Drugs? What are some so-called health preservation? Drugs? It is nephrotoxic, and long-term consumption will lead to kidney damage. In fact, scientific life can be healthy, and I haven't seen many. Healthy? How healthy you are.

If the kidney is broken, it will lose its renal function. At this time, the filtering function of the kidney will be lost, and even urine will not be produced. People can't live a normal life unless the waste formed by what they eat and drink is discharged. If the kidney is completely broken, you will get uremia. In addition to kidney replacement, only dialysis treatment can prolong life. Dialysis treatment is just a helpless coping style. Human toxins cannot be eliminated. After a period of time, blood can be excreted and filtered once with instruments and equipment similar to renal function, but how can it be compared with healthy kidneys filtered every day?

Drinking too much water won't hurt the kidneys, but it will hurt the body.

As mentioned earlier, the kidney is just a filter, and the amount of blood filtered every day is limited. Of course, this limit has some flexibility. But if you drink too much water at once, the kidneys can't filter it out, and the water will stay in your body, which will do harm to your body, okay? Water poisoning? .

Water poisoning does not harm the kidneys, but does harm to the body. When the total amount of water intake greatly exceeds the amount of water discharged, excess water will remain in the body, causing the plasma osmotic pressure to decrease and the circulating blood volume to increase. The main physical and chemical indexes of diagnostic test are the decrease of plasma osmotic pressure and the decrease of serum sodium dilution. The main symptoms are increased intracranial pressure caused by brain cell edema, such as headache, aphasia, insanity, disorientation, lethargy, restlessness, delirium and even coma. People with mild water poisoning will recover as long as they stop drinking water and discharge excess water from their bodies; But it may cause permanent damage to the nervous system and even death.

Water poisoning can be divided into acute and chronic, and acute is generally caused by sudden intake of excessive water. For example, some people often drink two cases of beer; Some people compete for water to see who drinks fast and much, and the result is not drunkenness, but? Drink water? , leading to acute water poisoning; Chronic water poisoning is generally caused by physical diseases, such as nephropathy, renal failure, decreased urination, etc. However, the intake of water exceeds the amount of urination for a long time, and excess water stays in the body, which will lead to chronic water poisoning.

Whether it is a healthy kidney or a sick kidney, drinking too much water will not discharge excess water in urine, but will harm the body, not the kidney, because the kidney is still a kidney, no matter how much water you drink, it is still a kidney. However, in the case of poor kidneys, drinking water will be limited when the urine output is very low.

So, how much water is normal to drink?

Water is the source of life on earth. Without water, there is no life. The water in the human body accounts for about 70%, that is, a 50kg person only squeezes out 15kg of water. The important functions of water in human body are as follows: it is an important part of cell protoplasm, and it acts as a solvent to dissolve electrolytes, transport nutrients, and take waste toxins out of the body, and as a heat carrier to transfer heat and regulate body temperature.

Therefore, water is very important to human body. Without water supplement, people can live for up to 3 days, and without food, people can live for 7~ 10 days. A healthy person can consume1500ml ~ 2000ml of water every day. Of course, everyone has their own habits, and drinking more or less is no problem. Drinking a cup in the morning and drinking some before going to bed at night is conducive to diluting blood and maintaining good blood circulation. Drinking water at other times is generally thirsty. Drink water if you want. There's no need to drink it deliberately.

Drinking more than 4000 ml of water every day may do harm to your health. Drinking more than this amount or more at a time may lead to water poisoning.

What is the best water to drink?

Drinking water is not the best, as long as it is hygienic and harmless.

There is no need to deliberately pursue water containing any nutrients. These nutrients are enough in our diet. There are also some people who promote the water with large molecules and small molecules, alkaline water, which is a totally deceptive gimmick. So far, there is no scientific evidence that this kind of water has any special benefits to health.

That's it. Welcome to participate in the discussion. Thanks for reading.
