The baby's epiglottis cartilage is not well developed, so the baby can inhale and swallow at the same time, but the adult can't. The total number of various germs living in the mouth every day will be more than the total population of the world! 80% of the fat leaves the body according to the lungs. This discovery is undoubtedly a great comfort to some people who like to overeat on holidays. Experts have found that more than 80% of the body's fat leaves the body according to breathing, making the lungs a key human organ for everyone to lose weight. There is a kind of fat in human blood called vaseline triglyceride, which consists of three atoms: carbon, hydrogen and oxygen. The release of unnecessary fat must open the atoms in the molecular structure of vaseline triglyceride according to the whole process called air oxidation. According to the way of tracking every atom in the human body, an elite team of experts from the University of New South Wales in Australia found that when 10KG fat is oxidized by air, 8.4KG fat will leave the human body in the form of carbon dioxide according to the lungs.

You can't suffocate yourself, because the instinctive reaction of human brain survival will make you suddenly inhale when you die of lack of oxygen! Breathing is controlled by the thalamus, but the thalamus is not controlled by your subjective consciousness, so if your subjective consciousness wants to suffocate, after a certain period of time, if you are unconscious, the thalamus will temporarily usurp the position and automatically let you breathe in. Eating more carrots will promote skin yellowing! Excessive intake of β -carotene causes "carotene anemia" and makes the skin appear transient yellow. The intake of many β -carotene generally does not produce toxic effects. After reducing the intake of beta-carotene for a few days or weeks, the symptoms will subside, which is harmless to the human body. The results showed that even if the daily supplement of β -carotene reached 180-300mg, there was no poisoning phenomenon. The human body has a lot of interesting cold knowledge, and because medicine has not completely deciphered the human body, with the passage of time, there will be more and more unpopular knowledge.

Blood circulation system It only takes 20 seconds for the human body to circulate once a week. If a person lives to be 80 years old, blood night will circulate in the body 1260 1440 times, which is extremely fast. When the human brain is closed, the working pressure in the aorta is the largest, and the pressure in the lumen at this time is called regulated pressure. This work pressure is enough to make the body's blood night spit out 9 meters. According to medical clinical research, heart disease is more likely to occur on Mondays. I know this very well. After all, I need to be sad at this moment when I go to work on Monday than when I visit the grave. Every member of the human body has 300 million cells that die, but actually it is not enough for 0.0005438+0% of the number of somatic cells that the human body replaces every day. About 10 trillion yuan to 50 trillion individual cells are upgraded in the body every day. There are 4.96 million germs attached to every cubic centimeter of human skin, but fortunately, most of them are harmless.

People's gastric mucosa should be removed and replaced every three or four days, otherwise gastric juice can digest the stomach. Several analyses from different countries show that the length of male vagina diameter is related to the length of index finger. 50% of human DNA is the same as that of banana and apple. Why banana apples? Incidentally, not only bananas and apples, but also humans and monkeys have 99% identical DNA. According to Phyllis? According to Dr. Frost, the genetic inheritance of many animals and plants controls human cells in a similar way. However, it is very different from the related parts of human bones and colors.
