50+ most surprising facts about the human body. Consider the most interesting and surprising facts about the human body. Read on!
“The human body is the best work of art.”
Jess K. Scott
Few things in the world seem as complex and interesting as our own bodies. Hundreds of thousands of years of evolution have made us one of the true wonders of nature.
But we don’t think much about it. Today we will reveal to you some of the secrets and secrets of your own bodies.
Interesting facts about the human body
Here are the most amazing facts about the human body!
People lose 600,000 skin particles every hour. This amounts to about 700 grams each year.
Did you know that the dust under the bed is your dead skin?
49. Bones at different ages
A child has 99 more bones than an adult. The skeleton of a child is mainly made up of cartilage. When a person grows up, most of this cartilage grows into “adult” bones.
Ossification occurs – the fusion of certain cartilages. Newborns have about 305 bones, while adults have only 206.
48. A few small pieces
An adult is composed of approximately 7,000,000,000,000,000,000,000,000,000 atoms. (For reference, that’s 7 octillion, or more than 7 trillion). Their amount depends on the person’s size and body composition.
47. Born to be an astronaut
The movies say that if you ever find yourself in a vacuum of space, you can disintegrate. Also, your blood may boil.
Not true! Our body is much more complex than cinema thinks. Many liquids boil in open spaces. But our blood is protected by the circulatory system.
Therefore, she is not afraid of open space. Freezing is not a problem either, as the vacuum functions as an insulator.
But that’s not all the good news: death in outer space will not be excruciating. Due to lack of air, you will pass out after 15 seconds. Death will come in a minute, and the body will float through space. Unfortunately, it will get ugly. This is all that scientists know.
46. Nose or eyes?
Researchers estimate that the average person can distinguish 1 trillion different smells. The human eye only perceives 10 million colors.
Noses are truly the highlight of the human body. We wildly underestimate them, but at the same time, we feel the world thanks to them.
45. Gross people
Are you ready to go crazy?
In a lifetime, the average person produces about 25,000 liters of saliva. This is enough to fill two pools. We also excrete about a liter of mucus a day.
Interestingly, saliva supports hygiene and health. For example, people with low salivation levels are more vulnerable to oral infections.
Your body is a source of beneficial elements.
There is enough iron in it to forge a metal nail 8 centimeters long; sulfur enough to kill all fleas in one dog.
There is enough carbon to make 900 pencils. Fat can be used to make 7 bars of soap. Phosphorus will make 2,200 matches. You can fill a ten-gallon tank with water.
These are the amazing facts about the human body.
43. “Close your eyes”
We all have tiny mites living on our eyelashes. These little parasites are not very picky: they will live anywhere as long as they have access to hair follicles. They can be found in various parts of the body of almost all mammals.
42. Strongest muscle in the body
The strongest muscle in the human body is the chewing muscle. The force of its compression is equal to 25 kilograms for the incisors and 100 kilograms for the molars.
41. Smelly people
Sweat itself is odorless. It is produced by bacteria that mix with the skin. Bacteria reside on our skin and multiply in high ambient temperatures.
40. Strong growth
Ears and nose will never stop growing. Until your death. Also, the earlobes can stretch out due to gravity.
39. Unique language
Like fingerprints, each person has a unique tongue print. Research on 3D visualization technology is currently underway. Therefore, after some time, the police can begin to take the prints of the tongue.
38. Steel Bones
Human bones are stronger than steel. 2 cubic centimeters of bone can withstand a load of 8,000 kilograms. That’s about the same as five pickups weigh.
37. Booze and blue eyes
People with blue eyes are the most tolerant of alcohol.
36. People 1, Robots 0
If the human eye were a digital camera, it would have 576 megapixels. Currently, the most expensive camera in the world has 200 megapixels.
If a robot uprising is inevitable, then it will be blurred.
35. Bacteria is man’s best friend
All bacteria in our body weigh about 2 kilograms. That’s enough to fill a giant bowl of (really disgusting) soup. You also have more bacteria in your mouth than there are people in the world.
34. Music and body
Slow and quiet music is used in the cardiovascular departments of hospitals. It relaxes patients, lowers blood pressure and heart rate.
This medical innovation goes back to some of the traditions of our ancestors. The ancient Greeks loved to use music as a method to calm the patient and relieve pain.
Native Africans and Americans also used chanting in healing rituals.
The facts about our body would be incomplete without mentioning the brain.
The brain makes up only 2% of body weight. At the same time, he consumes 20% of the total amount of oxygen and blood.
An amazing fact. This little gray ball weighs only about 1.5 kilograms. But it is precisely his merit that our species is called the crown of nature.
Interestingly, when it comes to intelligence, bigger isn’t always better. Cows, whales, and elephants have much larger brains than we do.
32. Deoxyribonucleic acid (DNA)
If you unfold human DNA, then its length is 10 billion miles. This distance is enough to get from here to Pluto and back!
31. Ultimate Betrayal
Within three days of the death, the enzymes that once digested your lunch begin to eat you up.
The ruptured cells will become food for bacteria in your gut. They will release enough poisonous gas to swell the body and make the eyes bulge outward.
30. Super storage
Over a lifetime, your brain’s long-term memory can hold up to 1 quadrillion bits of information. For our internal computer, this is incredibly high.
Interesting facts about the human body: The power of brain activity is equal to the power of a 10-watt light bulb.
29. Hot Dog Journey
The gastrointestinal tract is a 10-meter tube. It stretches from the mouth to the anus. Moving particles in the gastrointestinal tract push food, thereby regulating the digestion process.
28. Not so hairless monkeys
Humans have as many hair follicles as chimpanzees. But at first glance, it may seem that this is not so.
This is the catch. Human hair is incredibly thin and blonde. No one will say for sure why in the process of evolution we lost our fur coats.
Some people think it was an adaptation. The fact is that the thinning of the hair promoted better perspiration and got rid of fleas and ticks.
27. Electric Heart
Your heart has its own electrical impulse. This means that as long as it has a supply of oxygen, it will beat, even when separated from the body.
Your heart also pumps about 1.5 million barrels of blood throughout your life. This is enough to fill 200 tank wagons.
26 brain age
Your brain continues to develop until age 40.
25. Sweet eyelashes
Our lungs and nasal passages have tiny hairs called cilia. They can taste bitter. Their function is to cleanse the respiratory tract of dust and foreign particles.
24. “Can you feel me?”
Human fingers can sense objects up to 13 nanometers in size. This means that if your finger was the size of the Earth, you would feel the difference between houses and cars.
23. Hot body
The highest recorded human body temperature is 115.7 ° F. Temperatures above 107.5 ° F can damage the brain and cause death.
22. Touch your heart
The human heart is not on the left side of the body. It is located in the middle of the chest between the lungs while tilting slightly to the right.
21. Brain genes
Half of your genes are responsible for the brain. The other half are in favor of organizing the remaining 98% of the body.
20. Replacement of human cells
Your taste buds change every 10 days. In this case, the fat cell lives for about 10 years.
19. Shave or not shave?
There is no scientific evidence that shaving makes hair thicker. There are two reasons why this myth lives on.
First, observing people is not an accurate method.
Secondly, shaving makes the hair thicker. Yes, the mustache that a teenage boy shaves only gets thicker. But the reason for this is not shaving, but hormonal changes in the body. They are the ones that promote the growth of new and thicker facial hair.
18. Human differences
In 1 out of 10,000 people, internal organs occupy positions that are different from the norm. This condition is called situs inversus.
Interesting facts about the human body: 1 in 200 people has an extra rib.
17. Pinky – the powerhouse of the hand
Without the little finger, your hand will lose 50% of its strength. The index and middle fingers function with the thumb when squeezed and gripped. The little finger is combined with the ring finger to provide grip strength.
16. Keeping it cool there
Men’s testicles are not in vain between the legs. Sperm die at high body temperature, so the testicles must be cool. Keeping them cool is a top priority for men.
You’ve probably heard that the appendix is a waste of space. Just a relic of our earlier, less developed ancestors, i.e. rudiment.
Scientists have proven that this is not the case. The appendix had an important function: it was a “safe house” for the beneficial bacteria that live in the intestines. These bacteria have a positive effect on physical and mental health.
14. Amazing cells
Your mouth is made up of the same skin cells as your vagina. Flattened epithelial cells line the abrasion-prone areas of the body. Their peculiarity lies in the fact that they can be easily removed and replaced.
13. Cute little muscles
Muscle comes from the Latin “musculus” – “little mouse”. The term was used to nominate muscles because the biceps were thought to be like a mouse.
How do you know if you are surrounded by pathological liars? Quite simply, there is one amazing fact about the human body.
When a person lies, he blinks much less often than usual. Think of the shark-eyed TV killer. But after the lie is told, the deceiver starts blinking 8 times faster. Our eyelids are honest and try to signal deception.
11. Who said that?
More than 3% of people are born with phonagnosia: they cannot recognize the voices of familiar people. People who suffer from phonation do not suffer from aphasia, the inability to understand and formulate language.
This suggests that linguistic understanding and voice recognition are controlled by different parts of the brain.
10. Broken fingers will prevent arthritis
The scientist has broken fingers on one hand for more than 50 years. He tried to prove that it does not cause arthritis. As a result, the hand did not suffer from this disease, like his other hand. This is a small experiment, but quite interesting.
Hats off to a brave man who risked arthritis in the name of science and revealed such facts about the structure of the body!
9. Start your morning with sex
You can burn 20% more fat by exercising in the morning on an empty stomach. Sex burns 3.6 calories per minute. So, fifteen minutes of morning sex should burn 130 calories.
8. Complex genes
Humans have fewer genes than worms and tomatoes. How could this happen if a person is a more complex species? Scientists noted that the number of genes in a genome is a more complex issue than it might seem at first glance.
7. Cough at the speed of sound
A violent cough forces air out of the airways at speeds up to 620 miles per hour. This is equivalent to the speed of sound.
6. “Do you hear this? “
Hearing is the fastest organ of perception. Your brain can recognize sound 10 times faster than the eye can recognize an image. It’s only 0.05 seconds. T
So if you want to get attention, don’t wave your hands. Better to shout.
5. Dispute about bras
Bras make your breasts sag. They also do not relieve back pain. Studies have shown that women who did not wear a bra had a 7mm higher nipple position.
But this effect can only be in women who are not obese.
4. Recovering from the miracle of birth
After the birth of a child, a woman’s vaginal muscles need up to 6 months to return to their original forms.
3. Green diet
We cannot digest grass. Our body does not have a substance that would break down cellulose. An herbal diet will ruin your teeth too. It contains elements of silica, an abrasive that erases tooth enamel.
In grazing animals, unlike us, constantly growing teeth replace worn-out enamel.
2. The important thumb
Your thumb can handle more weight than any other. When leaning on it accounts for about 40% of your body weight.
1. And again about hair
Finishing with the most surprising, interesting, and amazing facts about the human body, let’s return to hair.
There are several theories that explain the presence of hair in the genital area. One of these theories states that hair affects the mating process. That is why ingenious hair has been preserved in the process of evolution.
Other theories say that hair traps secretions, thereby preserving odor. It was used by ancestors to attract partners.
So, we’ve covered the most amazing facts about the human body! Read Also: 78 Interesting Facts About Human Blood
