What does the heart smell like? Why is the collarbone easy to break? These are the facts about the body that few people know

The human body is everything that makes us up, yet there are many fascinating things that we ourselves do not know about it.

First, your brain regulates how strong your muscles are. For example, if your leg muscles contract to the maximum, they will break your femur. But the brain keeps that from happening.

That’s also why people in an emergency can lift huge loads, but a car to save children, which they normally would never be able to do. Or you can say, your body has very powerful capabilities, but that very thing can also cause you serious harm. So your brain has always kept your body softer than it really is.

When performing surgery, doctors sometimes have to take out some internal organs, but when it comes to repositioning, there’s no need to put them back in the correct position. That means your body has the ability to move organs into the right positions on their own, after surgery.

And if you care what the heart smells like, it smells like mushrooms, according to a cardiologist anesthesiologist.

People who have lived in “harsh” conditions for generations will adapt themselves in extreme ways. For example, people who live in high places often have larger lungs and a different blood composition. Or the Bajau, whose daily lives are on the water and spend a lot of time diving, have evolved to have their spleens become up to 50% larger, to be able to store more blood.

You often hate the sound of your recorded voice because it lacks the low frequencies you’re used to hearing. When you talk, you hear your voice as it travels through the air and back to your ears. It also travels through your skull to your ears, and this bone conduction mechanism transmits low frequencies better than air.

But the recorded voice has only the sound that travels through the air. That makes the difference between what you think your voice is and what it actually is. It’s also why your voice will (almost) always be at a higher pitch than you think.

On average, humans have as much body hair as chimpanzees. But human hair is much shorter and finer.

Your eyes have a separate immune system from the rest of your body, and in a lot of cases, if your body’s immune system “finds” your eyes, they’ll assume it’s a problem. foreign body and blind you.

Humans can bioluminescent and glow in the dark, but the light we emit is 1,000 times weaker than the human eye can perceive. So we can’t detect this luminescence.

When you cry and have a runny nose, it’s actually your tears.

The reason your collarbone is so fragile is because it was designed to break. The way it exists is like a circuit breaker. It breaks in place to prevent the shock of the impact from reaching your spine, and causing worse conditions.

Your body will lose muscle strength to protect your spine.

For example, stand on flat ground, raise your arms in a T, and ask a friend to push your arm down while you try to keep it stationary. It would take a lot of force to make that happen. But now, take off a shoe (or put a book under one foot) and repeat the same hip wiggle so your spine isn’t straight. It only takes a very small amount of force to push your arm down at this point.

Alzheimer’s disease is more than just gradual memory loss. It exists physically in the brain. If you could open the skull of someone with Alzheimer’s disease to look at their brain, you would actually see this sticky, fibrous, and gray matter covering their brain.

The eyeball is the fastest healing part of your body.

You will die sooner from lack of sleep than from lack of food. You can live, depending on your current health and fat level, for months without food. But it is estimated that you will die from lack of sleep within 2 weeks.

You can calm down by splashing cold water on your face, as that triggers the mammalian diving reflex.

Humans are one of the few mammals that do not produce vitamin C on their own due to a lack of certain enzymes. Other mammals that also exhibit this mutation are those in the major primate subspecies Haplorhinni (monkeys, apes, tapirs), as well as bats and guinea pigs. All other mammals produce vitamin C in the liver.

The thing that can grow new fastest after being lost on a human body is toenails.

Some women can sense exactly when an egg is released from the ovary during ovulation. And not everyone knows that women develop a new organ during pregnancy. That is, in addition to developing a child, their body also develops the placenta.

The surface area of the lungs is about the size of a tennis court.

Your body has to warm up the liquids before absorbing them, so drinking ice cold water only burns more energy and you won’t stay hydrated as quickly.

39% of people have extra bone in the knee. 100 years ago, only 11% of people had this bone.

Every minute you remove more than 30,000 dead skin cells from your body. And 30% of waste in the body is eliminated through the skin.

Your brain will continue to try to revive your body long after your heart stops beating. In some cases, up to 30 hours later, brain activity was still found trying to repair to bring the body back. This is used to find out the victim’s time of death in murder cases.

Humans have stripes, but normally we cannot see them. These are called Blaschko lines and form along the lines of embryonic cell migration. The stripes are U-shaped in front of us, V-shaped in the back, wavy on the head and face. And we also have basic and simple stripes on our limbs.
