The 'interesting and horrifying' truth about yourself makes you surprised

The human body always has strange things that not all of us know.

Our bodies are formed by many different system pieces. Every piece of this puzzle is the most perfect "apparatus" of creation, but hidden in it is a lot of miracles that sometimes you have to stumble, when you hear it.

And here are some amazing phenomena that happen in our bodies. Check now to know if you understand all about your body?

1. Tongue is the most flexible organ in the human body

It looks small but the tongue is really extraordinary and has great stamina when used regularly for eating, talking, swallowing but never gets tired.

That's because the whole tongue is muscle. But the tongue is not the only muscle that is formed from 8 different muscle types, tightly coiled together to form a flexible matrix.

Along with strong bonding, the tongue also shows agility and flexibility when combined with lips and teeth to turn sounds from vocal strings into syllables and words.

The ability to speak fast, slow, standard or not depends much on the high flexibility of the tongue. In a minute, the tongue can produce more than 90 words.

2. Our skin is really elastic

Did you know that 2.54cm of skin can last 2-3 times its actual size? And the man from England - Gary Stretch Turner named Guinness world record with the world's most elastic skin.

His skin was so loose that he could pull away from his body by 16cm. According to experts, Gary has a rare genetic disease called Ehlers-Danlos syndrome, which affects only 1 in 10,000 people.

The expression of Ehlers-Danlos syndrome is that the skin, joints become loose, sagging, bruises appear immediately after a strong impact or the blood vessels are easily broken - due to abnormal collagen production .

3. Not 1 but we have 3 types of tears

According to Robert Provine - professor of neuroscience and psychology at the University of Maryland (USA), we have 3 types of tears.

1. The most common type is " basal tear" - the kind of water that always exists in our eyes. It helps maintain moisture, improves eye function, and prevents infection.
2. The second type is " irritation tears". It is the kind of tear that comes out when your eyes meet certain factors, such as when you are in the act, or have an eye problem. It helps soothe the pain, along with some biocides to help your eyes heal faster.
3. Emotional tear - tears when we cry. This is the most mysterious kind of tears, because the experts so far have not really understood it.

Although it looks like a type, they are all different under a microscope.

4. Iris is a small and spooky muscle bundle

Under the microscope, our eyes appear spooky. The black part is the pupil, while the orange-colored area is the iris.

Muscle bundles on the iris are also tired of overworked. That's why our light response will be slower at the end of the working day.

5. Before forming, our face was originally a unified block

My face begins to form in the first 3 months of pregnancy. From an original ugly cavity, they bunched up in the middle of the upper lip, creating the groove that was the central part of the face.

Around 8-10 weeks of pregnancy, your baby's face, nose and upper lip are forming. The skin has begun to grow on the eyes forming eyelids. The root of the tooth began to appear in the mouth.

Until the 12th week, the chin and nose will form clearly on the face, the bones on the face are full and become more rigid.

6. Our teeth are always covered by a civilization of bacteria

We know that plaque always exists and adheres to the surface of teeth.

These are things that will appear when you eat and drink without brushing your teeth afterwards. Of course it is very dirty, even overflowing with bacteria.

Under the microscope, you will understand that plaque . is essentially bacteria, at a rate of up to 100%. It is an excess product of bacteria when consuming food on the teeth

The first few hours, they neutralize with saliva, then plaque becomes thicker and saliva cannot penetrate inside. Acid in plaque will begin to dissolve tooth enamel, causing our tooth decay.
