Interesting Facts from book
“Oddities of our body. Entertaining anatomy”
written by Juan Steven, trans. A.Davydova

Since ancient times, people have tried to understand the mystery of man. Scientists, philosophers, representatives of art and culture still cannot explain unique creation which is Homo sapiens. In this article we want to tell the most interesting facts about the structure of man. You will see that even at the biological level, we are incredibly precise and intelligent.

But first I would like to remind you that two sciences are engaged in the study of a person at the biological level: physiology and anatomy.

The structure and work of human organs

Of course, you guess that there is acid in the stomach that breaks down food. So the concentration of hydrochloric acid (and that's what it's called) is such that it can freely dissolve a razor blade.

The stomach has a lot of nerve endings, which is why scientists conditionally call it the “second brain”.

If all blood vessels stretched in one line, then it will be 100 thousand kilometers. It is mentioned that the circumference of our planet is 40 thousand kilometers. That is, with a rope of vessels, you can wrap the earth two and a half times.

Have you ever wondered what internal organs we could exist without? So, if a person's stomach and spleen are removed, leaving only one quarter of the liver, 20% of the intestines, one kidney, the only lung, and remove almost everything from the pelvic region, he will be able to live. Of course, this will not full life but still better than not existing at all!

The heart creates such pressure in the body that blood from the artery can squirt more than 7 meters.

The liver, despite its seemingly inconspicuous activity, performs up to 500 important functions in our body.

When smiling, about 17 facial muscles contract. But when we frown - 43 muscles. It turns out that it is much easier for us to smile than to frown.

Many even children know that in the morning we are one centimeter taller than in the evening. This is because during the day the cartilages of the spine are compressed, as it were, and during the night they return to their standard position.

Scientists have proven that the strongest muscle is the tongue. Interesting!

The tibia is the strongest bone in the skeleton. It can withstand more than four tons, and the next one is the femoral one - its indicator is 3 tons.

The heaviest bone is the jawbone.

Teeth are the only organ that does not regenerate.

If, reading the previous fact, you have a misunderstanding, then let us explain: a tooth is not a bone, but an organ.

At birth, a child has about 300 bones, and when he grows up - only 206. This is due to the fact that many bones grow together with age.

When we sneeze, air escapes from the mouth at a speed of 160 kilometers per hour, and in the process of coughing - 100 kilometers per hour.

sneeze with open eyes impossible.

It is well known that women blink almost twice as often as men.

Volume Bladder an adult is approximately 400 milliliters. Although, of course, some "talented" people are able to tolerate up to 1 liter!

How much saliva do you think is secreted in the mouth every day? If it were possible to collect the saliva secreted by you throughout your life, then it would be possible to fully fill two pools with it.

Feelings

Interestingly, after a hearty meal, our hearing becomes a little dull.

It is believed that two-thirds of the world's population does not have one hundred percent vision. And in the age of computerization, this figure is likely to increase.

If there were no saliva in the mouth, we would not be able to taste any taste at all.

Women have a more sensitive sense of smell than men, and every fiftieth inhabitant of the planet practically does not distinguish smells.

In general, the nose is able to distinguish up to 50 thousand smells and their shades.

When a person turns 60, they slowly begin to lose up to 50% of their taste buds.

Ears and nose always grow from birth.

The largest human cell is the egg and the smallest is the sperm.

Teeth in the fetus begin to grow after the third month of pregnancy. Already during this period, unique fingerprints are also determined.

With age, every second inhabitant of the earth begins to snore in his sleep.

Every 25-30 days, human skin is completely renewed.

Every hour, about 600,000 skin particles fall off the body.

Fingerprints are absolutely unique for all people. Language has the same property.

This interesting fact for adults. A man experiences an erection every hour and a half. However!

It's no secret that iron is present in the body. But did you know that it is enough to make a nail 10 centimeters long?

If the bedroom is cold during sleep, it is likely that you will be dreaming of something scary.

The average person generates enough heat in one hour to boil two liters of water.

When you are in stressful condition or you are afraid of something, then the sulfur in the ears is released in greater quantities than during calm.

Interesting, but impossible to tickle yourself. Our senses are too smart to react to this.

It is believed that the arm span is equal to height. This fact can be checked independently at home.

Not a single animal in the world can cry from an excess of feelings. Only Homo sapiens is endowed with such a gift.

Left-handers live a few years less than right-handers. But this is not a genetically determined relationship, but simply most things are adapted specifically for right-handed people.

Unique fingerprints, except for humans, have primates and koalas.

At the end I want to say one important thing. It has been proven that 90% of diseases are caused by stress. That's why, Dear friends, keep calm, as Carlson said, live long and do not get sick!

What you will not find in our body: an amazing zoo and mythical characters, mysterious plants and tools, colorful mosaic and a lot of edible things, geographical names and just funny words and objects. After all, anatomists use more than 6,000 (!) Terms to designate the most diverse nooks and crannies of our body.

Let's start with this phrase: “The entrance to the cave was guarded by an elderly gatekeeper, and there, inside, in the center of the labyrinth, in a crescent crevice, an amazing bird was sitting: a cockscomb, a wedge-shaped beak, fish scales; just fantastic!”

Amusing? But the most interesting thing is not so much in this phrase itself, but in the fact that it contains the names of several anatomical formations of our body.

Cave, scales, cockscomb... Can these ordinary words be anatomical terms? It turns out that they can, and besides, they are officially registered and accepted in all countries of the world. Human anatomy - the science of the structure of his body - is one of the most fascinating sections of biology and medicine. But also one of the most difficult. And anatomy is a beautiful scientific discipline. Her language is sweet-sounding Latin. Look at your palm. The palm is like a palm, and in Latin it is called the mysterious combination “palm manus” (palma manus). Even the place on which we sit is not called anything, but "regio glutealis" (regio glutealis).

Let's go back to our example. So where did the cave come from in the human body? In the meantime, there are even a few of them. One cave is part of the middle ear cavity, a special depression in the temporal bone, and the other is part of the stomach. By the way, the entrance to this cave, or rather, the exit from it, is really “guarded” by the gatekeeper. This is the name of the end part of the stomach, passing into the duodenum 12. Also, after all interesting name. The length of this gut is exactly a dozen cross-laid fingers. And the intestine itself is located in such a way that it forms a "horseshoe". However, this is a trifle compared to the cistern, which is also comfortably located in abdominal cavity. A chylous, or lacteal, cistern is the expansion of a large lymphatic vessel.

At the very beginning of the duodenum there is an extension called the bulb. That's really what there is more than enough in our body, so it's bulbs. They will be typed in a whole garden bed. They are in the duodenum, in the aorta, in the brain; hair follicles seems to be known to everyone, but only experts know about the bulb of the penis. What else is rich in our "anatomical menu"? Two apples: Adam's and eye (the first - on the neck, the second - it is clear where). There are also olives - a paired thickening of the brain stem. Not far from them are the almond-shaped and lenticular nuclei - special accumulations of the medulla.

"There are many things in the world, friend Horace ...". How can you remember this famous quote no matter how surprised. However, any organ of our body, any part of it, every nook and cranny of this body is truly remarkable. beautiful world in which we live without noticing it.

Among the many living beings that live on Earth, man is the most intelligent and most advanced in his development. The mind opens the way for us to self-knowledge, including understanding how our body works. Today, more than 6 billion people live on Earth. Each of them is unique in terms of personality, behavior, appearance, body proportions, manner of movement….

The voice is produced in the vocal cords of the larynx. The exhaled air contributes to their vibration and the appearance of sounds, which are then converted with the help of lips, teeth, tongue and palate into vowels and consonants of human speech. Sounds fly out of the mouth at a speed of 1200 km / h (340 m / s), speech flow at very fast speech is 300 words per minute, and the distribution radius ...

The human body consists of more than 50 trillion. microscopic cells. They perform certain functions that ensure the coordinated work of the body. Liver cells (hepatocytes) form tissue. This tissue, together with other types of tissue, forms the liver organ. The liver and related organs are combined into digestive system. The human body is arranged according to the hierarchical principle, i.e. as a sequence of different difficulty levels,…

If the average duration of one sound (for example, the note “la”) without changing the tone and on one click for most people is 20-25 s, then the record is 55 s. Singing voices are classified according to their sound strength as follows: Ordinary voice - 80 dB Concert voice - 90 dB Opera voice - 100 dB Voice in a comic opera - 110 dB ...

There are 12 major systems in the human body. These are muscle, bone, nervous, endocrine, circulatory, lymphatic, digestive, respiratory, integumentary (skin, hair and nails), reproductive (male and female), excretory and immune system. Each system is responsible for some one process or several processes necessary to sustain life. For example, the circulatory system, which includes the heart, blood vessels and blood, supplies all the cells of the body…

80 billion people have lived on Earth since the appearance of man (currently 5 billion people live, and 75 billion people have died). If you line up the skeletons of all the dead (7 skeletons per meter), then a queue is formed that is 26 times the distance from the Earth to the Moon (10 million kilometers). The total weight of these skeletons is 1275 billion...

There are 4 main types of tissues in our body. epithelial tissue, consisting of densely packed cells, covers the skin with a protective waterproof surface layer and lines gastrointestinal tract. Connective tissue connects individual parts of the body and performs a supporting function. Its varieties are tendons, bone and cartilage tissues. Muscle tissue is made up of cells capable of contracting and thereby causing...

Funny terms that bear the names of places, objects or topics of everyday life, we divided into several groups. Nature, geography, architecture The aqueduct of Sylvius is the cavity of the midbrain. The tree of life is a gyrus on the surface of the cerebellum; Atlas (atlas) - the first cervical vertebra. “Strait”, or “gorge” [transl.] - the opening of the pelvis. “Slope” [trans.] of the foot. Spaces and cavities “Gastric cave” [transl.] – stomach cavity….

Our muscles weigh 28 kilograms! Any movement, from blinking to walking and running, is carried out with the help of muscles. Muscles are made up of cells that have unique ability shrink. Most muscles work in pairs as antagonists: when one contracts, the other relaxes. The biceps muscle of the shoulder, contracting and shortening, bends the arm (the triceps relaxes at the same time), and when the triceps contracts (the biceps is relaxed), ...

Skeletal muscles Skeletal muscle cells (muscle fibers) are long and thin. They are formed by many parallel threads - myofibrils. Myofibrils also consist of filaments, or myofilaments, 2 types of proteins - actin and myosin - that give skeletal muscles a transverse striation. When a signal from the brain enters the muscle along the nerve fiber, the myofilaments slide towards each other, and the muscle fibers ...

There are a lot of "surprises" in the human body. Here are just a few figures and facts about the fascinating human anatomy and physiology.

The expression "scared to death" has its justification. Defense mechanisms of our body, in case of danger, adrenaline is added to the blood, which leads to improved blood supply to the muscles, dilated pupils and other “improvements”. However, adrenaline in large quantities is toxic to the body, so in some cases it can cause death.
Studies have shown that in Germany, on the days when the national team plays at the World Cup, the number of heart attacks increases sharply. And this is quite logical.

Even though the penis is not a bone, it can be broken. This usually happens when the penis is in an erect state and a force is applied to it in an unusual direction. When this happens, a crackling sound can be heard, after which the penis swells and remains in a “broken” shape. This can usually be corrected with surgery.
70% of people pick their nose, thirty of them do not interrupt this fascinating process even while eating.
