1. Chemical buffer.

Important chemical buffers are bicarbonate, phosphate, and protein. Chemical buffers act rapidly to protect tissue and cell function, and these buffers quickly bind to excess acids or bases, neutralizing adverse effects until other buffer systems are in their hands.

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 body maintains acid-base balance in the body through three pathways. The first is through the buffering system of the blood. There are a number of substances in the blood that can neutralize both acids and alkalis, the most important of which are sodium bicarbonate (NaHCO3, or baking soda) and carbonic acid (H2CO3), which have a ratio of 20 1.

When acid enters the blood, NaHCO3 neutralizes with it; When a base enters the blood, H2C....

Free radicals, also known as "free radicals" in chemistry, refer to atoms or groups with unpaired electrons formed by the homogenization of covalent bonds of the molecules of a compound under external conditions such as photothermal and other conditions.

To put it simply, in our world of atoms, there is a special law, that is, as long as there are more than two atoms combined, their peripheral electrons must be paired, and if they do not match, they have to look for another electron to make themselves stable matter. Scientists call these atoms or molecules with unpaired electrons free radicals.

Under the action of free radicals, collagen will react, so that **not enough nutrients**, resulting in **tissue vitality decline, loss of elasticity, wrinkles, aging of the whole body, dull complexion, etc. At the same time, with the increase of age and the increase of free radicals, the degree of free radical corrosion of protein cells and fat cells in the body is also deepening, and lipofuscin accumulates more and more, resulting in the slow formation and appearance of pigmentation.

Free radicals in the human body are divided into oxygen radicals and non-oxygen radicals. Oxygen radicals are dominant, accounting for about 95% of the total number of free radicals. Oxygen radicals include superoxide anion (), hydrogen peroxide molecule (H2O2), hydroxyl radical (OH·), hydroperoxy (H), alkyl peroxy (ROO·), alkoxy (RO·), nitrogen oxygen radical (NO·), peroxynitrite (ONoo), hydroperoxide (ROOH) and singlet oxygen (1O2), etc., which are also collectively known as reactive oxygen species (ROS), which are the most important free radicals in the human body.

Non-oxygen radicals mainly include hydrogen radicals (H·) and organic radicals (R·).

Free radicals are a very active, very restless substance, just like the bachelors in our human society who are not willing to be lonely. Free radicals are created when the original structure of a stable atom is broken by an external force, resulting in the atom missing an electron. So it will immediately look for the other half with whom it can be united.

It is reactive and easily reacts chemically with other substances. When it gains or loses an electron in the process of combining with other substances, it returns to equilibrium and becomes a stable structure. This activity of electronic gains and losses can be beneficial or harmful to humans.

SOD can effectively scavenge free radicals and protect the health and safety of human cells. In the case of insufficient SOD, it is very necessary to supplement exogenous SOD, such as Guao Bio SOD lozenge.

Free radicals, the culprit of aging.

Free radicals are molecular genes that carry unpaired electrons. There are many types of free radicals, and the free radicals used to explain the mechanism of aging are mainly superoxide radicals, hydroxyl radicals and lipid-like peroxide radicals. Among them, the products of superoxide radical action are strong oxidants, which can oxidize the unsaturated fatty acids in lipid-like to lipid peroxides.

Under normal circumstances, due to the presence of free radical scavengers in organisms, such as sex hormones, SOD, catalase, etc., the production and removal of free radicals in organisms are relatively balanced, and participate in many normal physiological and biochemical reactions. If the synthesis of free radical scavengers is malignant or the free radical response is disordered, it will lead to a series of pathological changes in the body.

Eating organic selenium + vitamin C + vitamin E can be antioxidant.

I look at the beautiful and quiet beauty today, and I will see it every day in the future, but it's a pity that I forgot what free radicals are, haha,

It's very simple, since you're a student, do some research in school.

1. In what kind of environment can students be most interested in learning 2, in a high school, the proportion of students with various hobbies 3, what aspects of school education are students very dissatisfied with, how to improve, what are the good suggestions4, during the vacation, what is the main scope of activities of high school students, activities and activities5, what are the main aspects of the current high school students' feelings about the future, the above content is just a little I thought about casually, you can also add your own content to investigate, Divide these contents into categories, make a questionnaire, conduct a poll in your school, or conduct a random sample survey, and then analyze the results of the survey to see the current learning status and motivation of high school students. This information, if well organized, is very helpful for the management of the school. Your research is mainly from an objective standpoint, thinking about both the school and the student, so that it will not be extreme.

The current education reform is not very satisfying. If you do a good job in your research and research, you can also provide some reference and opinions for schools or educational circles.

There is an environment above, in fact, I think it may be more feasible for you to do a social survey, and it is more demanding for appointment. For example, to investigate the operation of the local nursing home, whether people are satisfied with the work, etc. You can also do a market survey to compare how local people view the current housing market, and you can take a certain group of people to conduct a survey.

It's a way for you all to be involved, and it's challenging, but you can definitely do it with hard work. Hope it helps. The specific plan will also be discussed by your group, depending on your specific situation.
