Scientists have long studied the human body as a living person, and many interesting facts are known about it. However, some of them are quite unusual and unbelievable! Although science claims that this is true, there is no reason to disbelieve in the best minds of mankind
Facts about the human body
- Our brain utilizes 20% of all oxygen in the blood. And the power it produces is not enough to light a 10-watt lamp.
- The nerves in the human body move at an amazing speed of 400 km / h. So there is a "signal delay", but it is ignored.
- The largest organ in the human body is the lungs. If they are spread out on the ground, they will take up space like a tennis court.
- A human bone can withstand a load 5 times more than steel of the same size, but it is weaker and can break if hit hard enough.
- The human body without body tissues could not move at all. Up to 200 muscles are used to complete a single step (interesting facts about muscles).
- Our eyes will never shine like an eagle. However, the human eye is so sensitive that if the Earth were flat, we could clearly see the flickering of a candle 30 miles [48 km] away. As long as there are no vision problems, of course.
- The number of bacteria in the human body exceeds the number of cells that make up the body itself.
- On average, the adult body produces about 25 million new cells every second. They replace those dead cells very quickly.
- The smallest human tissue is found in the ear. The largest is the gluteus maximus, which moves the legs.
- Human hair can weigh up to 100 grams, and men's hair is twice as thick as women's hair.
- The stomach can digest almost anything. Stomach juice contains hydrochloric acid, which can dissolve even iron.
- Many scientists agree that nails are an unnecessary part of the human body. There are theories that in some stages of evolution, man will lose it as an unnecessary part of the body.
- In nature, there is no such thing as a perfectly bald person. Each of us has the same number of hairs per square inch of body as a monkey. But almost all of these hairs are short, simple and thin so that you cannot see them with your physical eyes.
- If you stretched 300,000,000 capillaries into your lungs from start to finish, the line would stretch about 1609 miles.
- Like deep-sea creatures, humans are naturally bioluminescent, which means they glow in the dark. However, the light emitted by the human body is surprisingly weak. It is so weak that human eyes cannot distinguish it.
- People shed tears arranged differently depending on the cause of our crying. Emotions such as grief, guilt, sadness or happiness lead to dramatic changes in the structure of the tear cells. Like a snowflake, there is no such thing as molecularly sad.
- Our brain consists of flesh and tissue smaller than fluid and is 80 percent water. However, a large part of the human body also has it.
- Sneezing has a real function. Eliminates any congestion in the nasal cavity and throat. The power of sneezing is so great that it exceeds speeds of 160 miles per hour, and during sneezing, the heart stops for a while.
- Eye color depends on the spread of the pig in the anterior layer of the iris. Brown is the most common eye color in the world (interesting facts about the eyes).
- The smell is gender dependent, and women often surpass men in sensitivity, awareness and distinction of smell. The sense of smell is especially strong in children, but loses 40-50% in the first year of life.
- The average person travels about 100,000 miles [160,000 km] in his or her lifetime, equivalent to the length of the four-equator earth.
- The aging process of the human body and its possible regeneration are studied in the science of gerontology.
- Certain organs in the human body grow throughout life, such as the nose and ears. Some, on the contrary, are declining. For example, the adrenal glands.
- Over time, we humans lose our sense of taste. By the time we are 60 years old, about half of our taste buds are dead.
- The human body is experiencing changes in the way it grows. Newborn babies have about 300 bones, but some grow together. and for adults only 206.
