The human body is a highly complex and complex system that continues to confuse physicians and researchers on a regular basis despite the medical knowledge gained over the years. It should not be surprising, then, that there are strange and unexpected facts and explanations about the parts of the body that we witness every day. From sneeze to nail growth, there are 100 funny, weird, and interesting facts about the human body.
Although we do not pay much attention to our internal organs, we eat, breathe, and move through them. Here are some things to think about when your stomach sounds.
- The largest internal organ is the small intestine. The smallest of the two intestines is four times longer than the average adult. If it were not creased back and forth, it would not fit into the abdominal cavity.
- The heart produces enough pressure to allow the blood to flow 9 meters. No wonder we can hear the heartbeat so easily. To deliver blood quickly and efficiently throughout the body requires a great deal of pressure to ensure that the heart and the thick walls of the forearms are strongly compressed and pump blood to different parts of the body.
- Stomach acid can damage the razor blade. But you don’t need to eat metal stuff to check the strength of your stomach. The acid in the stomach is called hydrochloric acid and it can corrode not only pizza but also various metals.
- Man has about 60,000 miles of blood vessels. To better understand, the length of the Earth is about 25,000 miles. If blood vessels were aligned, they would be twice the length of the Earth’s circumference.
- Every 3 to 4 days stomach gets a new interior wall. If the mucous cells surrounding the stomach walls are not constantly replaced by new ones, the stomach lining will destroy them. People with ulcers know how painful it is to have stomach acid on the stomach walls.
- The lung surface is the size of a tennis court. To provide blood with oxygen effectively, the lungs contain thousands of branching bronchi and small, alveolus-sized grooves. In turn, they contain microscopic capillaries that exchange oxygen and carbon dioxide. The larger the surface of the lungs, the easier it will be to perform this exchange.
- A woman’s heart beats faster than a man’s. The main reason for this is simply that women tend to be smaller in composition and that blood is pumped to a smaller and less mass. But the heart of the two sexes can work quite differently, especially when traumatized by a heart attack.
- Scientists have calculated about 500 liver functions. The liver is one of the most functioning, most occupied and largest organs. Its functions include degradation of red blood cells, gall production, plasma protein synthesis, detoxification and so on.
- The diameter of the aorta is approximately the diameter of the garden horn. The heart of an adult is approximately two fists in size, and consequently the size of the aorta is also large. The artery should be so large that it would provide the whole body with oxygen-rich blood.
- The left lung is smaller than the right lung to allow enough space for the heart. If most people were asked to draw lungs, they would think both right and left. While the heart is located more in the center of the chest, it is slightly tilted to the left, “narrowing” the left lung.
- If most of the body’s internal organs are removed, one can continue to live. The human body appears fragile, but it can survive in the stomach, spleen, liver, 75%, intestine, 80% of the intestine, one kidney, one lung, and in fact, all the organs of the kidney and groin.
- The size of the adrenal gland changes throughout life. Located just above the kidneys to the right, these glands produce stress hormones, such as adrenaline or cortisol. At the 7th month of gestation, the glands are about the same size as the kidneys. During childbirth, they become smaller and continue to shrink throughout life. And in old age, they are barely visible.
The most complex and least discovered part of the human anatomy is the brain. We don’t know much about the brain, but here are some facts.
- Nerve impulses travel to and from the brain at 170 miles (273.59 km). Have you ever wondered how you can respond to a phenomenon so quickly or why your foot hurts when you hit something hard? It is the result of high-speed movement of nerve impulses from your brain to the whole body and vice versa.
- The brain works at about the same amount of power as a 10-watt bulb. You will notice in the cartoons that, after coming up with a great idea, a light shines on the hero’s head. now it makes more sense, doesn’t it? Your brain produces as much energy as a small bulb, even while sleeping.
- The brain cell can contain about five volumes of encyclopedia information about 30 volumes. The exact number of scientists has not yet been determined, but by electronic terminology, it is assumed that brain capacity is expected to be 3-1000 terabytes (1 terabyte = 1000 gigabytes). The British National Archives, which has a history of nearly 900 years, occupies just 70 terabytes, making the memory of the human brain very impressive.
- The brain uses about 20% of the oxygen in the blood stream. The brain makes up 2% of the body mass but consumes the most oxygen at the same time. Therefore, the brain is highly susceptible to the potential loss of oxygen. So take a deep breath to let your brain cells swim in the oxygen pool.
- The brain is more active at night than in the day. If we were to move logically, we would have thought that active activities during the day would require more energy and strength than, for example, lying in bed at night. But actually, on the contrary. when we are “switched off”, our brains are “switched on”. The reason for this is not yet known, but we can thank our brains for good dreams.
- Scientists say that the higher a person’s IQ, the more a person dreams. This may be true, but don’t think you have mental disabilities if you can’t remember what you dreamed of at night. Most people cannot remember their dreams, except that the average duration of the dream is 2-3 seconds. hardly enough to register.
- The neurons are constantly growing. For years, doctors have suggested that the brain and nerve tissue cannot grow and recover. Although growth does not occur as other tissues do, neurons do indeed grow throughout our lives, bringing research into the brain and related diseases elsewhere.
- Different neurons transmit information at different speeds. The neurons are not alike. The transfer speed can range from 0.5 meters per second to 120 meters per second.
- The brain doesn’t feel pain. Although the center of pain felt by cutting or burning a finger is the brain itself, it has no pain receptors and does not feel pain. This, of course, does not mean we will not have headaches. There are thousands of vessels, tissues, and nerves around the brain that are quite susceptible to pain and can cause severe headaches.
- 80% of the brain is water. The brain is not the solid, gray mass seen on television. The living brain is a soft, slimy, pink and jelly-like organ due to its high blood vessels and high water content.
Muscles and bones
The muscles and bones provide the outline and structure of the body. Through them we walk, jump, sit, and lie down.
- It takes 17 muscles to breathe, and it requires 43 to breathe. If you don’t want to train your face, choose the cookie option. Anyone who has long blinked or blinked their eyes knows that the face is tired as a result, but the mood does not improve.
- The baby has 300 bones since birth, but by the age of 20 it has dropped to 206. The reason is that most of the newborn’s bones are small and not merged. this facilitates the baby’s passage through the vagina. As the bones grow, the bones grow and merge.
- In the morning one is about 1 cm taller than in the evening. As a result of various physical activities, the growing bones between the bones shrink and shrink during the day, and at the end of the day we appear slightly slower than in the morning.
- The tongue is the strongest muscle. You can’t make body presses in a language, but it’s the strongest muscle in the body by its size. Indeed, if we think about it, language is trained every day, because it does the job of talking, chewing, swallowing every time.
- The strongest bone is the jawbone. The latter is the strongest and the most late-breaking bone.
- 200 muscles work in one step. This is quite a lot of muscle work, as people do about 10,000 steps a day.
- The tooth is the only component of the body that does not recover. The outer layer of the tooth is called enamel. it’s not a living tissue. And because it is not a living tissue, it cannot recover. Hi, dentist?
- To lose muscle requires twice as much time than it gained. But the lazy should not use this fact as an impetus to train. Getting muscle tissue and getting into good physical shape is relatively easy, so use this fact as a motivation to get up and exercise on the couch.
- Bone is stronger than some steels. However, bone is subject to fracture because it is less dense than steel. The bone has about 138 kPa and the bony 70,000 kPa. Steel is heavier than bone, but kilograms per kilogram, bone is nevertheless the strongest material.
- The bones of the feet make up the ¼ of the body bones . Of the 200 bones, 52 are giants with legs.
