8 secrets of the body

Fracture is a disaster, everyone knows. But not everyone knows that spongy bones and becoming brittle are a way for the body to protect itself.

The human body is a perfect machine. Biochemical flows and mucus are always moving and mixing. In the multitude of complexities there are secrets that seem impossible to exist but are an essential component of the magic of this living machine.

Gastric juice - dangerous poison

It can be confirmed that no matter is safe from HCl acid, a corrosive chemical used to treat metals in the industrial sector. With a strong enough concentration, this acid can remove metal. However, stomach cells are unharmed before it, even the mucous membrane of the stomach wall retains this type of poison to distribute throughout the digestive system to break down food.

Broken bones are for mineral balance

As a support and support system for organs and muscles, the skeleton is responsible for regulating calcium levels in the body. The biochemical composition of bone has both phosphorus and calcium, which are then metabolized, needed for muscle and nerve systems. That's why when calcium is deficient, some functional hormones will cause a fragile and brittle fracture reaction of the bone, in order to concentrate the calcium needed for the whole body. It is only when the mineral level in the cell reaches the relative concentration that the bone condition gradually stabilizes

Although it accounts for only 2% of body weight, the brain needs up to 20% of oxygen and body energy. To keep the brain healthy enough to store nutrients, the brain's three main blood vessels continually pump oxygen. Any minor problems in these blood vessels, such as blockage or tear, will starve brain energy cells, which are essential for controlling and correcting regional functions. The end result was a fatal stroke.

Waste of eggs

On average, a girl in puberty has about 34,000 unripe follicles, but only about 350 of them ripen until menopause, 1 fruit per month. When a woman enters the late 40s and early 50s, the two ovaries produce less estrogen; Unripe follicles begin to deteriorate and do not release to the uterus as before. They will destroy themselves.

Big head, small mouth

Evolution is not perfect; otherwise we will have wings instead of wisdom teeth. But these useless bodies always follow many species, simply because they are harmless. Long before humanity evolved completely, wisdom teeth acted like triple chews, helping to crush food. But when the brain develops, the jaw bone structure also changes, leading to the appearance of the final teeth as unwanted promotional gifts.

Laugh and yawn contagious

Just by looking at someone yawning, you may have the same reaction.

Laughing too. A recent scientific evidence shows that this behavior is a kind of social imitation. Just hearing a crisp laugh is enough to stimulate the area of ​​the brain that makes your face move, making you laugh. This mimic action plays an important role in social interaction. Reactions such as sneezing, laughing, crying and yawning are all about the same way as creating a strong social connection.

Four colors of skin on the body

Blood vessels near the surface of the skin always add red pigment and combine with a golden brown pigment to create a unique brightness for each area. When the dark brown pigment produced after reacting to ultraviolet rays, a large skin surface will turn black. It is these 4 colors that mix with different proportions to create the individual shades on the body as well as the skin color of the races.

Memory stimulating space

You can't remember the birth date of your wife? Kneel down and do a flower gesture. Your memory is affected by your senses, a familiar sight or sound can also evoke certain distant details from your childhood.

According to a study, the sound of bicycle bells can make us remember the old road to school. Past memories are now faster and clearer when the subject is in the same position as before.
