What is the body s acid base balance? Does he have anything to do with sub health status 5

Sub-health refers to the non-disease and non-health state, which is a kind of secondary health state (sub-means inferior), which is the state between health and disease, so it is also called "secondary health", "third state", "intermediate state", "free (shifting) state", "gray state" and so on.

In the normal metabolic process, the human body constantly produces acidic substances and alkaline substances, and also ingests acidic substances and alkaline substances from the daily diet, and acidic substances and alkaline substances are constantly changing in the human body, and this change must rely on the body's regulatory function to maintain relative balance. This equilibrium is the acid-base balance, and the range of the equilibrium is the pH value. This pH is best suited for cellular metabolism.

and the survival of the whole organism. All physiological changes and biochemical reactions in the human body are carried out under stable pH conditions, such as cell protein synthesis, energy exchange, information processing, enzyme activity, etc., all need a stable pH.

Environment. Laboratory experiments have shown that if the pH of a person's blood is higher or lower, a person will develop a lesion. The pH of the blood varies very little, and the difference can be close to death, and the pH of those body fluids that remain in the body can vary greatly, such as duodenal fluid, gastric juice, urine, and fecal oak bushes.

Serious illness occurs when a person's bodily fluid pH is below neutral 7.

When Liang cherry descends, it will become a vegetative person, and if it is only a person, it will die, and of course, a high pH will also lead to alkalosis in the human body.

Therefore, the human body needs acid-base balance to maintain the health of life.

Balancing pH is a major concern for health and beauty. Should the human body be acidic or alkaline? If it should be alkaline, pay special attention to the weak alkaline. The normal pH of the body's body fluids.

It should be, if you deviate from this value, the chemical reaction within the cells of the body.

The speed will vary significantly.

Acid-base balance is an important factor in the regulation of the environment in the body, and it is also an important condition for maintaining normal physiological activities. Under normal circumstances, the human body can excrete excess acidic or alkaline substances through autoregulatory action to achieve weak alkalinity.

The body is a method to maintain acid-base balance: 1. The buffering effect of the blood, when the strong acid or strong alkali enters the human body, a certain substance in the blood will be combined with it to form a weak acid or weak alkali, which makes the strong acid become weak acid, and the strong alkali becomes weak alkali. 2. Metabolic acid-base balance disorders are compensated by the lungs, which compensate by increasing or decreasing the emission of carbon dioxide.

In metabolic acidosis, the respiratory center is excited, breathing deepens, and ventilation increases, and in metabolic alkalosis, the concentration increases, and the respiratory center is inhibited, and breathing becomes shallow, and ventilation decreases. 3. Hudan cavity suction acid-base balance disorder is compensated by the kidney, and the compensatory regulation of the kidney is completed by retention or expulsion. 4. The exchange of ions inside and outside the cell:

In acidosis, extracellular H+ increases, and H+ enters human cells and K+ moves out of cells, resulting in hyperkalemia. In alkalosis, K+ enters the cell and is buried indistinctly, resulting in hypokalemia.

One of the key factors for people with acidic constitution is that the body fluids of acidic people are a hotbed for cancer cells, and acidic constitution is very conducive to the survival, metastasis and spread of cancer cells. On the contrary, alkaline constitution is able to effectively fight cancer, and cancer cells cannot survive. The vast majority of people with cancer, high blood pressure, hyperlipidemia, and gout are acidic.

Therefore, it is necessary to maintain the acid-base balance of the human body.

The human body regulates acid-base balance in four main ways. The buffering effect of blood: when a strong acid or strong alkali enters the human body, a certain substance in the blood (we call it a buffer substance) is combined with it to form a weak acid or a weak alkali, which makes the strong acid become a weak acid, and the effect of a strong liquid chain alkali becomes a weak alkali is the buffering effect.

When acid-base balance disorders occur, the blood's buffering system immediately acts as a buffer, reaching a peak in 15 minutes, but the buffering capacity is limited. Metabolic acid-base disorders are compensated by the lungs: the lungs compensate by increasing the amount of trouble or decreasing the amount of energy that is excreted.

Because if there is an imbalance between acid and alkali, the concentration of hydrogen ions in the body fluid is too large or too small, which will lead to a chemical reaction and denaturation of the body fluid components of the human body, affecting the body function. Moreover, some processes necessary for human life activities also need to be carried out in an environment with moderate acidity and alkalinity, and excessive acid or alkali will affect these processes, thus affecting normal life activities.

Because of the acid-base imbalance itself, it is easy to say that it is easy to put it bluntly, and it cannot be discharged, and it is said that the broad branches are to put it bluntly, and the cherry blossom is what people call gout, and it is easy to commit, so it is necessary to have an acid-base balance, so it is said that it is necessary to achieve an acid-base balance, so it is a manifestation of the healthiest person's body.

The human body needs to maintain acid-base balance, because acid-base imbalance will harm people's physical and mental health. The pH level is between the healthiest state of a person. If there is an imbalance of acid-base in the mold, it will lead to vomiting, diarrhea and other problems, which will affect the health of the body.

Because the acid-base balance of the human body plays an important role in the health of the body and the normal operation of various organs, people with excessive acidity are prone to suffer from a variety of diseases.

Of course, it is necessary to maintain the acid-base balance of the human body, if the balance is out of balance, too much water or too sodium, there will be corresponding diseases.

Because only by maintaining the body's acid-base balance will the body be healthy.

For the health of the human body.

There are a variety of acid-base buffer pairs in human body fluids, such as carbonate bicarbonate buffer pairs, dihydrogen phosphate phosphate hydrogen phosphate buffer pairs, and so on. When the acidic substances in the human body increase, such as ingesting too much acidic drugs or foods, the alkaline components in the buffer pair will be neutralized with the acid, and when the alkaline substances in the human body increase, such as taking a large amount of sodium bicarbonate, the acidic components in the buffer pair will buffer off too much alkali to maintain a relatively stable acid-base balance in the human body.

Maintaining the acid-base balance in the human body depends on the acidity and alkalinity of the food ingested and the regulation of the acid-base balance by the excretory system. The acidity and alkalinity of food refers to the result of the metabolism of food in the body after digestion and absorption. If there are more phosphates, sulfates, chloride ions and other ions produced after food metabolism, it is easy to form acids in the body and produce acidic reactions.

If there are more sodium ions, potassium ions, magnesium ions, and calcium ions, it is easy to produce more alkali in the body and form an alkaline reaction. This has to do with the mineral content of the food. Generally speaking, foods that contain more minerals such as sulfur and phosphorus are acidic foods; Foods that contain more minerals such as potassium, calcium, and magnesium are alkaline foods.

Some foods, such as oils, sugars, starches, etc., which are very pure, basically do not fit the above two types of elements, so they are neutral foods, and these foods do not affect the pH of body fluids. It can be seen that the so-called acidic food cannot be understood as a sour food, and the final effect of sour fruits such as tomatoes, oranges, hawthorn, bayberry, etc., on the human body after being metabolized in the body is alkaline.

So what are the common alkaline foods? Such as tofu, peas, soybeans, mung beans, rape, celery, sweet potatoes, lotus roots, onions, eggplants, pumpkin, mushrooms, radish, spinach, cabbage, cabbage, lettuce, lettuce, shiitake mushrooms, carrots, bamboo shoots, potatoes, konjac, kelp, seaweed, citrus, watermelon, grapes, bananas, apples, pears, strawberries, chestnuts, persimmons, milk, wine, etc. So what are the main acidic foods?

Such as rice, flour, animal meat (beef, pork, mutton, chicken, duck, etc.) and eggs.

Generally, the daily staple food requirement of middle-aged and elderly people is 300 400 grams. If you eat some alkaline root foods such as sweet potatoes and potatoes, the amount of staple foods can be appropriately reduced. Animal meat is the most important acidic food, and it should generally be controlled within loo grams per day.

Usually eat more alkaline foods such as vegetables and fruits to avoid acidic constitution.

pH balance refers to a steady state in which the pH of the blood is usually maintained within a range under normal physiological conditions, i.e., the arterial pH is stable between averages.

Excessive or insufficient production of acids and alkalis in the body causes changes in the pH of the blood, a state called acid-base imbalance. The maintenance of basic life activities mainly depends on the delicate acid-base balance in the body or the stability of the internal environment, and even a small imbalance may greatly affect the body's metabolism and the function of vital organs.

The normal value is, first, check the pH value, which is fundamental to understanding other indicators. < pH indicates acidosis; pH", indicating alkalosis. The analysis of metabolic or respiratory acidosis or alkalosis is then based on other indicators.

The acid-base balance of the normal human body is mainly regulated by chemical buffers, the respiratory system and the kidneys, each of which has different effects

1. Chemical buffers (bicarbonate, phosphate and protein):

Chemical buffers act very quickly, and some buffers quickly bind to excess acids or bases, neutralizing adverse effects until other buffer systems are functioning.

2. Respiratory system:

The respiratory system is the second line of defense against acid-base imbalances, retaining or expelling acids from the body through underventilation or hyperventilation, allowing for rapid pH adjustment in minutes.

3. Kidneys. The kidneys play an important role in maintaining acid-base balance in the body by reabsorbing acids and bases or excreting them in the urine. The kidneys' compensatory regulation of acid-base balance works over hours or days.

The human body mainly passes.

BAI three ways.

DU regulates acid-base balance: cellular pathways, renal pathways, respiratory pathways. Return.

1. Answering the cell pathway:

The main extracellular ions are sodium ions, chloride ions; The ions in the cell are mainly potassium ions, bicarbonate ions. When the acidity of the body fluid changes and needs to be adjusted, ions can be exchanged to adjust the pH of the body fluid, such as acidosis, the hydrogen ions in the extracellular fluid will be exchanged with potassium ions, changing the acidic environment outside the cell.

2. Renal pathway: This is the most important humoral regulation pathway in the human body. The kidneys have a strong excretory and reabsorption function. For example, in alkalosis, the kidneys excrete excess alkali and reabsorb acid. to maintain acid-base balance.

3. Respiratory routes; The carbon dioxide we exhale can be regarded as an acidic substance, so when the body is acidosis, the breathing will deepen and accelerate, so metabolic acidosis is easy to form Coosmo's large breathing.

The pH of a healthy person's blood can be stabilized within the range because the human body has a well-established acid-base balance regulation function. The body itself has a compensatory function, which can be metabolically regulated at any time to maintain acid-base balance. The organs that regulate acid-base balance are mainly the lungs and kidneys.

For example, if the body has too much acid, it can break down the typical acidic carbonic acid into carbon dioxide and water, and excrete the excess carbon dioxide from the body through the lungs, or through the kidneys, or add alkaline substances to neutralize the acidic substances and keep them in balance. On the contrary, if there is too much alkaline substance in the body, the excess alkaline substance can be excreted through the kidneys, and at the same time, acidic substances can be used to neutralize the alkaline substance to achieve acid-base balance. However, the body's own regulatory function is limited, if the metabolic disorder continues to worsen, beyond the compensatory function, it breaks the normal acid-base balance, it is called acid-base imbalance, that is, pathology.

The body's self-regulating system of acid-base balance mainly depends on the following aspects:

1) Rely on the blood buffer system to regulate acid-base balance.

2) Regulate acid-base balance through pulmonary respiratory function.

3) Regulate acid-base balance through the excretion or reabsorption function of the kidney, although the human body has a perfect acid-base balance regulation function, but only within a certain range of qi action. Acid-base imbalance occurs when certain metabolic diseases cause accumulation of acidic intermediates, excessive acidic or alkaline substances in the diet or medications, lung and kidney dysfunction, and imbalance of water and electrolytes, and acidic or alkaline substances in the body exceed the body's ability to buffer and excrete them, and the blood pH level cannot be maintained within the normal range.

Generally, it mainly relies on monohydrogen phosphate, dihydrogen phosphate and CO2 to maintain the acidity and alkalinity of body fluids, and there is a special gastric juice in the stomach that shows strong acidity, which is not balanced by this.

The pH of the human body is between. A person can balance the acid-base through various methods. For example, the stomach is hydrochloric acid, and the food forms chyme in the stomach and then enters the duodenum, in order to prevent gastric acid from corroding the digestive tract, the liver and pancreas secrete the alkaline substance HCO3 - digestive juice neutralizes with the acid in the chyme.

The carbonic acid H2CO3 produced by the human body itself can also be excreted through the respiratory breath of the lungs (in the form of water and carbon dioxide after decomposition). Carbonate H2CO3 can also be turned into H+ and HCO3- through the action of the kidneys, of which HCO3- can be used to neutralize acids in the body.
