100 amazing curiosities about the human body

Often people think that we know their body very well, how it works and the processes that take place in it at all times.

But in fact, the human body is so complex and mysterious that it sometimes confuses even the best connoisseurs, doctors and scientists.

The human body is a very complex and very complicated system, which despite thousands of years of studies still surprises researchers with the new things they discover.

Why is man special? Because our body is full of surprises and incredible abilities.

For example, you know that man can live without food for 70 days, but I cannot live without sleep for 11 days. Did you know that the surface area of ​​our lungs is equal to that of a tennis court?

Did you know that without the little finger, a person would lose 50% of their hand strength? Or that information passes through human nerve centers at 400 km per hour? Or that human teeth are as strong as shark teeth?

A man can live without most of his organs. Our body may look weak, but it can survive without a stomach, without 75% of the liver, 80% of the intestine, and without a kidney.

100 amazing curiosities about the human body

39- Although it may seem unbelievable to you, but for every square centimeter of skin, an individual has approximately 32 million bacteria. It seems unimaginable actually, but it is true. However, it is not to alarm us and terrify us, since a good part of these bacteria are harmless and without consequences for our organism.

40-A strand of hair can hold the weight of an apple.

41- Have you ever wondered why we cut our toenails less often than our fingernails? Because the nails, which are more exposed, grow faster than those which stay hidden. There is even a difference between the hands, as the nails grow faster on the hand you write with and on the longer fingers.

42- Sleep is very important for humans. You can go weeks without food, but just 11 days without any sleep at all and you fall asleep forever.

43-The forms and signs in language are unique to each person.

44- It is known that an adult has fewer bones than a small child, and yet what not everyone knows is the fact why this happens. Babies, according to studies, have approximately 350 bones in their entire body. Over the years, as a person grows, the bones fuse with each other, and so, in adulthood, a person has 145 fewer bones, or 205 bones in total.

45- The source of body odor, including that of the feet, is sweat. In fact, the feet are among the body parts that sweat the most. Together, they can produce about 500,000 sweat drops per day.

46- The colder the room you sleep in, the more likely you are to have bad dreams.

47–A person produces about 600 millimeters of saliva every day.

48- Our ears secrete more wax when we are scared than when we are normal. Hormones and chemical reactions that occur when we are afraid cause the production of wax in our ear to increase. Although the phenomenon in question has been studied and demonstrated, the causes are unclear to scientists.

49- It is impossible to tickle yourself. Even the most sensitive people will never have the ability to tickle themselves.

50- The strongest muscle of our body is the tongue and the strongest bone of the body is the jaw.

52- Teeth are the only part of the body that cannot repair itself. All this, because teeth are not a "living" part of our body.

53-The speed of receiving impulses from the brain is 400km/hour.

The human brain is capable of memorizing 5 times the information contained in the Encyclopaedia Britannica, or any other type of encyclopedia. .

54- Only the brain uses 20% of the oxygen that enters our body and is transported in the blood. The cerebral mass is equal to 2% of our body, but it consumes more oxygen than any other part of the body.

55-During blood circulation in one day, it covers a distance of 19,312 km.

56-The total length of nerves in the human body is 75 km.

57- A person takes about 20,000 breaths a day.

58-The human eye can distinguish up to 10 million different colors. But our brain cannot remember everything.

59- Facial hair grows much faster than any other hair on the body. If you are a man, you know very well how fast the beard grows, just think that if a man did not cut his beard during his life, the latter would grow to be more than nine meters long.

60- Humans bat their eyelashes an average of 4,200,000 times a year. Also eyelashes are the strongest human hairs.

61- The finger that grows the fastest is that of the middle finger. To be more precise it is the fingernail that you use the most. Moreover, the speed of nail growth is closely related to the length of the fingers, although it is not yet well known why.

62–Our ears grow during life by 1/4 of a millimeter per year.

63- Hair looks indestructible. In addition to being able to catch fire, hair is able to not decompose even after death. Hair cannot be destroyed by water, cold, or climatic changes, and is very resistant to various acids or chemical agents.

64- The largest organ of our organism is the small intestine (intestinum tenue). Although it is called "small intestine" by the English, it is 4 times longer than the average length of an adult.

65- The human heart produces blood with a pressure to pump it up to 9 meters high. So don't worry if you can hear your own heartbeat. To pump blood throughout our body in such a short time requires a good pressure from the contraction of the heart.

66- It is thought that the human body has more than 96,000 kilometers of blood vessels. By doing a simple calculation with our dishes two trips around the world can be made in less words.

67- Gastric juices are capable of digesting even a razor blade. Every 3 or 4 days a new mucous membrane is created in our stomach. This is due to the great strength of the acids present in the stomach and those who suffer from ulcers can understand very well how painful these acids are, especially when they attack the walls of the stomach.

68-In 1 square centimeter of our skin, there are about 100 pain sensors.

69-Men have fewer taste sensors in their tongue than women.

70- A man can live without most of his organs. Our body may look weak, but it can survive without a stomach, without 75% of the liver, 80% of the intestine, and without a kidney. You probably wouldn't feel very well, but the missing organs wouldn't kill you.

71- The blood in the human body travels very fast. From the heart to the toes it takes 16 seconds, to the brain in 8 seconds, to the lungs in just 6 seconds.

72- An average person consumes about 35 tons of food during his life.

73- Our skin has four colors. Even white skin has 3 other hidden colors. So close to the veins the skin turns red. The skin is also accompanied by yellow pigment in its parts. The last color is black and is influenced by melanin. This causes the skin to appear black in large parts of it. All four of these colors mix and create different colored people across the globe.

74- Maybe it is better to play basketball in the morning, because our bodies are on average one centimeter more than in the evening. It may sound strange, but according to science, a person in the morning, after sleeping, is slightly taller than during the day. This happens because the interannular cartilage discs contract (contract) during the day, and stretch at night.

75- When we laugh, the brain activates 17 facial muscles, while when we cry, 43 muscles are activated.

76- You breathe more than 20,000 times a day! In one month hair grows 1 centimeter, in one year 13 centimeter. If they didn't cut their hair all their lives, they would be 10 meters long.

77- Blood circulates through blood vessels 100 thousand kilometers in 23 seconds. This speed of blood circulation is 215 times greater than the speed of ships in the universe. In 11 seconds, 25 billion carrier trucks loaded with essential oxygen and nutrients (red blood cells) unload their cargo through the starved cells of the blood capillaries. The life of red blood cells lasts 42 days, although they can live up to 127 days in the face. This means that our blood is renewed every 2 months, so 200 billion red blood cells are born and die every day.

78- The diaphragm, the muscle that separates the chest cavity from the abdominal cavity, is the most active muscular organ during human life. This organ never rests. This muscle contracts (contracts) 11 thousand times per hour, about 264 thousand times during the day or 670 million times for 70 years of life.

79- Our brain is the most perfect computer in the world. It consists of 100 billion cells, equal to a power of over 10 thousand computer programs in permanent operation. The area of ​​these computers is 250 thousand km² (half the area of ​​France). Let's add something: it takes a little love and intimacy to give birth to the new creature, the human. No computer can ever do that.

80- Cyclones and anticyclones rarely exceed the speed of 130 to 140 km per hour, while the speed of the air coming out of the lungs through the vocal cords during sneezing reaches a speed of 390 km per hour.

81- Digestion of food is carried out in all links of the organs of the digestive system. It takes at least 12 hours for the body to digest food.

82- How many times has our heart beat when we are 79 years old? Scientists have solved this question. About 2.5 billion times.

83- At the end of his life, his body produced 950 kilometers of hair, while his eyes were closed about 415 million times.

84- The temperature of the human body is lower when we wake up in the morning, compared to the temperature the body shows in the evening. A temperature of 37 degrees Celsius at 7 in the morning may indicate a fever, while at 5 in the afternoon it may be normal. Due to the rhythm of the body, it has been discovered that the human body is more predisposed to suffer a heart attack in the early hours of the morning. And this condition is almost 2 times more dangerous than at other times of the day.

85- Child births are also more frequent in the morning and evening hours, also due to the progress of the rhythm that the organism follows.

86- But the rhythm of the organism also shows the changes that occur in the psychic sphere, which can also be followed by damage if disorders occur. Because of these disorders, some suicides are committed in the early hours of the morning. For this reason, even the medical prescriptions given by doctors follow a certain schedule. According to the most frequent cases, medications are usually taken in the morning and at dinner. For example aspirin and antihistamines would have a more complete effect if taken in the morning. But some types of medication, for example cancer chemotherapy, may be more effective if given at night.

87- People usually like sex at night, right before bedtime, compared to other moments during the day. If we lived in complete darkness, we would follow such a day-night cycle that would exceed 25 hours. The "genetic clock" controls body temperature, hormone secretion, and many other activities at the cellular level.

88- The speed of a human sneeze is 160 km/h.

89- If you want to preserve your identity, be careful, don't stick out your tongue. It is a way of saying how in fact, just like the fingers and their prints, the tongue and the mark it leaves is defining for an individual. Each of us is unique at this point.

90- Until today, no one has been able to discover the mechanism in the brain which causes our laughter. But the only truth rests on the involuntary: only human beings are prone to laughter, and children begin to laugh when they are 4 months old.

91- It seems that our brain works like a computer, in the hours of sleep, staying constantly in operation. This was discovered by a study conducted by the University of Los Angeles. While we are sleeping, our brain archives memories without ever stopping and organizes the information collected during the day. Meanwhile, he is preoccupied with "deleting" all unnecessary data.

92- The front part of our brain, as you know, is divided into two hemispheres, the left and the right. Each of the two has distinct characteristics and functions: the left side controls language, while the right side perceives images. Or otherwise, the "engineer" that is in us is hidden in the left part, while the "poet" is in the right part. Also interesting is that the right side controls the left side and vice versa.

93- Our brain is composed of hundreds of billions of neurons and many blood vessels: if they could be joined and put all in a straight line, they would reach about 100 thousand kilometers in length!

94- Cerebral pain does not exist! In the brain, there are no pain receptors. This is one of the reasons why surgeons can perform brain surgery on an awake patient. This allows them to monitor the situation and make sure they don't disrupt any cerebral function.

95-Appendicitis is part of the digestive system. In early man, it performed the function of continuing the digestion of food. In today's man, appendicitis has lost this function, being a waste of the digestive system. Most of the population have it removed after surgical interventions.

96-80% of the brain is water which means you need to be careful of dehydration.

97- The amazing computing power of your brain only requires about 10 watts of power to operate.

98- The brain can store everything, technically, your brain has the capacity to store everything you have experienced, seen, read or heard.

99- You have to leave the water tap open for at least 45 years to equal the amount of blood that is pumped through the heart on average throughout our lifetime.

The 100-Skeleton is an engineering marvel which is composed of 206 different bone parts joined together. The human body, thanks to these parts jointed with each other, possesses an extraordinary ability of movement. The bones are extremely strong and able to be easily used, even in places where the bones are jointed with each other there are signs of creation, the rubbing surfaces of the joints are covered with a layer of thin and pupal cartilage and in this layer there is a slippery fluid, if the ashtray presses it in any place, this fluid from the pupae comes out and enables the surface of the joint to slide like oil. Thanks to this perfect construction, man performs his movements with omniscience and great speed.
