皮肤——身体最大的器官（Skin -- the largest organ of the body）

皮肤——身体最大的器官（Skin -- the largest organ of the body） 皮肤——身体最大的器官(Skin -- the largest organ of the body) (1) what a beautiful thing a flawless skin is. We take care of it, nurture it, and try to improve it. However, we usually just "take it as a layer of skin", in fact, this misunderstanding and underestimation of the skin. Human beings have never created sensors, shields, and bulletin boards better than they have. (2) the skin is a good protective cover. It's the outermost layer, the skin, thinner than the Sharon packing film. It is resistant to dirt and water. Tightly knit epidermal cells form a strong barrier that retains moisture and keeps unwanted moisture out. The dead and detached cells are arranged compactly on the surface, making the skin more tenacious, like a transparent armored garment. The skin's intelligence is even admired by the army, and the skin that is made up of cells will strengthen the skin as soon as it is needed. Melanin producing pigment cells can resist the number one enemy of the skin - sunlight, sunlight on the middle layer of the skin - dermal damage is particularly large. (3) contains a lot of dermal collagen, it can tighten the skin with collagen has been degraded, will produce wrinkles and make the skin relaxation. Underneath the dermis is subcutaneous fat, which softens the texture of the skin. There are also blood vessels, hair follicles, sweat glands, and oil producing glands in the skin. These little things swim in the chemical messenger hormone plasma, and the white blood cell walks along. A large number of nerves are busy shuttling, transmitting information from the brain to other organs. Receiving good sensory endings, eyes open, careful observation and careful handling of our surroundings: We caress the soft petals of roses, but shrink from fear of being pricked by the pricks. (4) the skin is a powerful interface between the mind, the body and the outside world. The neuro immune skin endocrine network treats the skin as an independent, untamed sage. It tells us a lot about its owner. Think about it; if you accidentally reveal the secret of your heart, you blush; when something goes wrong, the skin will give you a warning from pimples; the shrinking skin reveals your fear. It is also as an endocrine organ full of life, for the other part of the body manufacturing like vitamin D, as well as their use of steroids and thyroid hormone, although it's not clear why, but found that many neurotransmitters in the brain is made by the skin. (5) in addition, the skin is an important sentinel of the immune system. The communication between thought and skin is much more than we see. For example, in the absence of itching or slapping, the brain can make you feel itchy without any external cause. Emotional stress can affect the protective function of the epidermis or cause inflammation in the skin. The skin has specialized white blood cells that can eat invading microbes and trigger systemic immune responses. Because the skin effect is outstanding, so researchers want to challenge the old test, the rinderpest vaccine injected directly into the muscle in this lack of immunity, it can reduce the pain, which is similar to pulmonary tuberculosis test. Although only a small portion of the dose was used, the effect seems to be good. (6) there are also gender differences in the skin. Perhaps because of the evolutionary process, women stay at home, while men in outdoor brave hunting, so the female skin thin and less fat than men, women's skin more easily by sunlight and cigarette smoke damage, easy long wrinkles, sweat and women less than men, so it is easier to heat stroke. 1, read the full text, please tell me this article describes what aspects of the skin content? 2, the use of multiple methods for example, as an example and analyzes its function. Give an example: Effect: Article 3, paragraph (4) the underlined part give three examples, three examples of this is to illustrate what / 4. One of the following mistakes about the content of the article is () A, skin is a human sensor, protective cover and notification device. B consists of dermis, epidermis, blood vessels, hair follicles, sweat glands, and oil producing glands. The underlined part in C and paragraph 5 is to specify the idea that "the communication between the mind and the skin is much more than we see.". The word "D" added to the last paragraph is used correctly, indicating that it is a guess of the author. 5, "it (skin) as an endocrine organ also has a full life", what is the meaning of "substantial life" here? 6, combined with the content of the article and health knowledge, to the familiar people around you to introduce several ways to prevent premature skin wrinkles. (at least 3 species) [answer] 1, structure, function and the reason of female skin easy to wrinkle (or sex difference of skin) 2, there are many ways to illustrate the method. Skin, for example, is the sentinel of the immune system. The skin to the front of the sentinel, vividly illustrates the skin immune system off the immune system and the information directly to the skin. (other examples can only be understood in the process of analyzing action.) 3, in order to explain, "it will tell us a lot about the situation of its owner", or to illustrate "the skin is an independent, difficult to tame the wise."". (any answer can be) 4, B. 5. Making vitamin D, steroids and thyroid hormones for other parts of the body, and making neurotransmitters. 6, (a) to prevent or delay the degradation of collagen in dermis; (two) to avoid sun exposure; (three) do not smoke or not long time stay in multiple room; (four) to participate in physical exercise; (five) excessive alcohol drinking; (six) pay attention to nutrition, a balanced diet (; seven) psychological balance; (eight) use the prescribed anti wrinkle drug and injection etc.. Just list three ways to make sense of Science
