What s wrong with human physiology?

The eyelashes are there to protect the eyes from dust, foreign objects, sweat, etc., but they are the ones that go in the eye.

After human beings evolved to walk upright and learned to use tools, they were much ahead of other animals, and now many people say that humans are superior animals, more advanced than other animals.

However, as a human being, do you know that there is something irrational about human physiology? If you don't know, you'd better find out! The temple, about the temple, should be dominated by everyone, this is one of the dead holes of human beings, it is distributed behind the corners of human eyes, although the human skull is the hardest bone of the body, however, the position of the temple is not, but the thinnest and most fragile position of the skull.

In addition, below the temples are numerous arteries and veins, such as the middle meningeal artery and the middle meningeal vein"Trigeminal nerve"with"Ciliary ganglia"Wait, the temple is the interweaving point of these arteries and veins. Further down is the temporal lobe of the brain, which is responsible for processing auditory information and is also associated with memory and emotion.

Therefore, the temple is very important, and the consequences can be serious once it is injured, but this part is left open and there is no protection. Therefore, there is something unreasonable.

Vomiting, vomiting, everyone should have experienced it, vomiting is actually a protective mechanism for the human body to deal with food poisoning. When the body feels that there is an abnormality or a foreign body in the digestive system, or is in the process of being poisoned, it will react with vomiting to expel some food that is not good for the human body in the stomach.

Especially when you really have food poisoning, vomiting is really effective. However, this vomiting mechanism is a lot of the time"Misdiagnosis"You might make it so bad that you don't know what's going on, and then you just throw up.

When humans give birth, when many other animals give birth, the mother can give birth and cut the umbilical cord herself, and many small animals can move quickly throughout their lives, such as chimpanzees or actual primates, but humans cannot.

There are two reasons for this: (1) even if a woman's pelvis is relatively wide, it is still too small compared to a human head, because the human head is relatively large, so the production process will become very difficult, and the pain of women will be aggravated a lot, so it is more difficult to squeeze out; (2) The woman's birth canal is very tortuous, and if she wants to give birth to the child, she first turns in the birth canal, and then the fetus does not know the way, so it will impact and rotate about twice.

Compared to other animals, there is nothing unreasonable about human physiology.

Existence must be useful, so even if there is something unreasonable, it is reasonable.

There is nothing unreasonable, and there is nothing unreasonable about human beings because of their continuous evolution.

Human physiological phenomena are all inevitable, and they are all signals given by the body to themselves.

There is nothing irrational about human physiology according to human evolution.

Humans evolved from four-legged walking to upright walking, and the angle of the body relative to the ground changed

From the point of view of evolution, from crawling to walking upright, there is a great process of physiological change from walking upright to the present.

The mechanism of vomiting in humans is very irrational.

The physiological structure of the human body is basically reasonable, and it has been constantly evolving and changing over the centuries. Functionally, it seems that every organ has its irreplaceable function, which may be the result of long-term human evolution and adaptation to nature. Most of the current environment is reasonable, but human beings are still evolving and changing, and some irrational places will gradually be replaced.

In fact, it is normal for human physiology to be irrational, and it is not a strange thing. This is a natural condition in the evolutionary process. Moreover, evolution never stops, and humans are still evolving.

In the face of the future environment, we may have other so-called unreasonable situations. But there is more than one irrationality. Humans evolved from four-legged walking to upright walking.

The angle of the body relative to the ground has changed, and the bone structure has changed, but the physiological structure has not kept up in time. Therefore, cervical spondylosis should occur due to discomfort in the head and spine. Most of the weight of the body is shared by the limbs, which is carried by the spine instead, resulting in lumbar spondylosis.

When the body is upright, gravity acts on the internal organs, leading to diseases such as stomach prolapse.

The improvement of human intelligence has greatly promoted the development of the brain, greatly increased the brain volume of the fetus, made the fetal head too large, and brought great difficulties to the development and birth process of the fetus. Human omnivorous and cooked foods render the cecum and appendix useless. However, the cecum and appendix have not yet degenerated and disappeared, and bacterial infections often occur, which can be life-threatening and require surgical removal.

These phenomena show that human evolution is not perfect, and there are many irrational places, and there are still far from the perfect level of evolution.

In fact, biological evolution is far from being the "ultimate body", but has been adapting to the environment. When the earth's environment changes, some populations that cannot adapt to the environment will become extinct, and individuals who can adapt to the environment will be preserved. Under this natural selection, living beings have some imperfections, such as difficulties in childbirth, and the inability to achieve immortality.

This is not an inherently irrational design, but rather a series of sacrifices made to adapt to the environment.

There is only one heart. Nerve cells cannot be regenerated, and the position of the brain is very prominent, making it easy to get injured. There are a lot of risks in the human body, and there are also some cancer cells.

Teeth, will bring us a lot of trouble, spine, cervical spine, knees, elbows, legs, these structures are unreasonable, it is not easy for human beings.

Human wisdom teeth, appendix, third eyelid, tonsils exist unreasonably, except for pain, no other function, and the forehead is the strongest position in the human body, but the temple is the weakest position.

The first temple is exposed, the second pelvis is too small, the third female has frequent menstruation, the fourth brain is slowly developed, and the fifth human has a vomiting mechanism.

Nerve cells, spine, elbows, legs, brain, these structures of the human body are all somewhat irrational.

If primitive people live in the wild, there are many unreasonable places, such as the brain volume, especially the proportion of energy consumption, the small visual range of the eyes, the sparse hair, etc., which are not conducive to wild hunting, making it difficult for humans to survive in the wild.

I feel the most unreasonable place, is the eruption of wisdom teeth, it is really very unreasonable, obviously this tooth is not needed, but it has to grow out, and it is easy to become inflamed, and it is easy to compress other teeth, and it is unbearable to pull it out!

In ancient times, wisdom teeth were used to grind food, but with the development of human civilization, food has become more and more refined, resulting in the complete loss of wisdom teeth, and it will also cause tooth decay due to dirt and dirt.

First of all, I think the first unreasonable is that people will suffer from cervical spondylosis if they sit for a long time, and the process of giving birth to a child is also very painful.

The place where I feel that the physiological structure of the human body is not reasonable is the belly button, because it is more prone to hernia. There are straight inguinal hernias, oblique inguinal hernias, these are very common diseases. In addition, the retina of human beings is reversed, so it is easy to cause retinal detachment.

And the human pelvis will be very small, which will easily lead to dystocia.

The human body is very complex, and the organs inside perform their own functions and maintain the functions of the human body. There are many good designs in the human body, but there are also some physiological designs that are not reasonable, such as the human appendix, feet, and spine.

The appendix used to work, but now it has no real effect. In the early days, human ancestors directly ate plants, and at that time there was a need for an organ in the body to digest plant fibers, and the appendix came into being. Later, as humans continued to evolve, the appendix gradually lost its usefulness.

Today, the appendix does not play a role in the body, but it has not evolved and disappeared, and it still exists in the human body, sometimes becoming inflamed. If the inflamed appendix is not treated in time, it can also cause sepsis, which can be a threat to people's health.

Human feet are overly complex, causing unnecessary injuries to humans. Our feet support human walking, it's not big, but it has 26 bones inside. In the early days, our ancestors lived on trees, and their complex feet made them very flexible and could hold branches with their feet at will.

However, when humans walk on the ground, it is clear that such feet do not need to be so complicated. Humans don't need so many bones to work together when they walk, and some bones become redundant, and in some cases increase the risk of cruralgia in humans.

The human spine is not durable. Human ancestors were originally reptiles, and the spine was designed according to the specifications of reptiles. By the time humans walk upright, the spine is overwhelmed.

Now in old age, the spine will bend and you will also have back pain.

The above three places are irrational aspects of human physiology, some of them are redundant, some are embarrassing and heavy-duty, and they all need to be improved. The human body has lived on the earth for so many years, in fact, it is constantly adapting to nature, gradually evolving, and perhaps in many years, these will be solved. In fact, there are many unreasonable things about human beings, and they can only be improved slowly over time.

The eyelashes are there to protect the eyes from dust, foreign objects, sweat, etc., but they are the ones that go in the eye.

What is irrational about human physiology? After reading it, I was terrified.

The mechanism of vomiting in humans is very irrational.

Yes, that is the duodenum in the human body, commonly known as the cecum. If you can't digest food, it will become inflamed.

The appendix is the most useless in the human body, and scientific studies have shown that the appendix has no effect on the human body, but in some cases it can harm the human body and needs to be removed.

The unreasonable part is that you will accidentally bite the meat in your mouth, and it will swell and become inflamed.
