Women are divided into several stages according to their physiological characteristics, from the fetal period to the neonatal period, and then into childhood and adolescence. With the decline of ovarian function, women gradually enter menopause and old age. At different stages, the physiological characteristics of women are constantly changing again.

1. Fetal period

Sperm and egg combine to form a fertilized egg, which is implanted in the uterine cavity and then gradually develops into a fetus. There are 23 pairs of chromosomes in the body, one of which is decisive for development.

2. Neonatal period

Because the fetus is influenced by the mother’s hormones in the uterus, the breast, ovary, uterus and vulva have developed initially. After the baby is born, the hormone level in the blood will drop rapidly, and it is easy to have a small amount of vaginal bleeding. Don’t worry too much, it will usually subside in a few days.

3. Childhood

Girls grow faster in childhood, but the reproductive organs develop slowly. Before the age of 8, the function of hypothalamus-pituitary-ovary axis was inhibited, the reproductive organs were not developed, and the vaginal epithelium was weak and wrinkle-free, which could not resist pathogenic bacteria and was prone to inflammation in children.

4. Adolescence

Girls enter puberty from the age of 10 to 19, and their reproductive organs develop rapidly, and their sexual functions are gradually improved. They begin to have menarche and their breasts develop accordingly. In adolescence, all parts of the body develop rapidly, and the secondary sexual characteristics gradually emerge.

5. Sexual maturity

Sexual maturity, that is, ovarian functional maturity, results in periodic secretion and ovulation of sex hormones. Usually from the age of 18 or so, after 30 years, this period is a period of vigorous fertility. Due to the influence of sex hormones, breast and reproductive organs also undergo periodic changes.

6, menopausal transition period

Generally, women begin to enter the menopause transition period from about 40 years old, which generally lasts for 1~10 years. During this period, ovarian function gradually declines, follicles cannot mature and eggs cannot be excluded, so menstruation becomes irregular. When it develops to a certain extent, the follicles in the ovary can be gradually exhausted, which will lead to the decline of ovarian function and eventually enter menopause. Because the estrogen level fluctuates greatly or suddenly decreases, it is easy to cause mental symptoms, leading to night sweats, poor sleep quality, irritability and hot flashes, which is called menopausal syndrome.

7. Old age

When a woman enters old age, the follicle stops, and the ovary can no longer secrete estrogen, but the ovarian stroma can secrete some androgen. Under the action of peripheral tissues, estrogen can be transformed into circulating estrogen. After women reach the age of 60, the ovarian function has completely lost, not only the body is aging and changing, but also the reproductive organs are slowly shrinking and aging. The main symptom is that the estrogen level is low and it can’t resist pathogenic bacteria, which leads to senile vaginitis. Abnormal bone metabolism also easily leads to osteoporosis, which in turn leads to fractures.

Tips

Girls should do a good job in nursing at any time, pay attention to personal hygiene at ordinary times, change their underwear once a day, avoid sharing the same room during menstruation, and change sanitary napkins at least once every two hours. In addition, lead an honest and clean life, master the correct contraceptive methods, and do not take emergency contraceptives indiscriminately, so as to avoid disrupting endocrine and hormone levels, and even make women enter menopause or lead to amenorrhea in advance. Adjust the diet, supplement nutrition reasonably, and do not lose weight by excessive dieting, so as not to affect the development of reproductive organs.

When it comes to culture, some people say that I went to college and studied as a graduate student, so I am a literate person. In fact, this is just a person’s education and diploma, not a real culture.

So, what is culture? Broadly speaking, culture refers to the sum of all material products and spiritual products created by human beings. Nowadays, there are many interpretations of the definition of culture, but in any case, culture can not be separated from literacy, and culture can not be separated from consciousness. A literate person is a person who can strive for goodness, progress and progress, a person who pursues personality charm, and a person who can be strictly self-disciplined. Such a person is a literate person with connotation.

Culture, culture, is to educate people. Wen is a civilization, and Wen is a literary spirit! Human society, from ignorance to civilization, this is the progress of society and the development of the times. A person with quality is a person who can arm his mind with culture. Such a person is a literate person and a civilized person.

Literature needs literature, but also needs culture. We should "create" people with literature and inspire people with literature, so as to keep pace with the times, keep pace with civilization, keep moving forward and strengthen ourselves. The Chinese nation has a long and splendid history and culture of 5,000 years, which makes us proud and glorious. The ancient sages have left us countless famous sayings that inspire people’s minds. These are the great wisdom of life, from which we can absorb spiritual nutrition, implant culture in our hearts, infiltrate into people’s bone marrow, and become a powerful spiritual driving force for life growth.

Culture and culture are precious in a word "Hua", and culture can be imperceptibly influenced; Culture can be passed down; Culture needs the unity of knowing and doing, being a man should talk less and do more, keep a low profile and do things with a high profile, which is the charm of culture. People live in reality, the commodity economy is a pluralistic society, colorful, singing and dancing, and all kinds of temptations come to us. Many people can’t stand the temptation of feasting, forget their initial heart, lose their kindness, empty spirit, impetuous mood, money first and self first; Some people make a lot of money, but they have no spiritual support, and eventually they fall down on the road of life.

There was a network anchor named Viya. In two years, she evaded taxes by 643 million yuan, and finally the tax authorities fined her a total of 1.341 billion yuan. She earns hundreds of millions of dollars a year. Some people don’t understand why she should do such a thing as tax evasion when she earns so much money a day. To put it bluntly, it is greed, which is the lack of culture. The lack of greed has been verified in her. People, if they leave morality and kindness, they will be greedy and will eventually be harmed by greed. Such examples are heard from time to time in reality.

A person can make money without money. Modern society provides everyone with a platform for self-development. As long as a person can work hard and strive for self-improvement, he can find his own life stage. If a person has no morality and culture, even if he earns a lot of money, he will eventually "spit it out". This is called settling accounts after the autumn, which is also called what goes around comes around, and what goes around comes around comes around. This is the causal relationship of life, and it is also a cultural embodiment of being a man.

To be a cultured person, this culture is to be a self-disciplined person, a person who can control his own behavior, a person who can control his own mouth, and a person who can control his own behavior. Perhaps some people will say that it is really too difficult and too bitter to be a man like this. In fact, suffering is also a kind of culture. If you eat bitter, you can be a master. If you don’t be a master, you have to consciously look for bitterness. This is a self-disciplined life. If you don’t suffer hardships in life, you won’t get rewards. Take pleasure in suffering, take pleasure in suffering, and strive for a life. This is the culture of being a man and a man with literacy.

Only when all personnel in the region control the community have been detected twice within 48 hours, and the resultIt is normal. After the comprehensive research and judgment of the previous epidemic prevention and control department can be issued, the unblocking instruction can be issued. Once the nucleic acid test results in the region are controlled abnormal, the control time will be extended accordingly. "

"I Jinshan" added: "The number of nucleic acid detection has soared in the near future, and the test report time is relatively prolonged, which affects the time and control time. The current situation of the epidemic prevention and control is severe and complicated.The principle of less contact and less gathering "promotes home online office."
