5 of impossible things that your body does every day
As the stomach digesting itself, and why we run the risk of cancer up to 1000 times per den
What do we do to stay alive? We breathe and eat, with desirable that these processes took place close to a sofa and TV. But our bodies are working overtime every day and solve extremely complex problems that we do not even suspect.
1. Your kidneys are literally trying to piss tastes, exploring it for toksinov
The taste and olfactory receptors are concentrated not only in my head. Over the past decade, researchers, to his great surprise, found that these special cells scattered throughout our body, they are in our tissues and organs such as the kidneys, heart, spine, upper respiratory tract. Cells have receptors even in the red blood cells. Initially, experts believed that it was some kind of anatomical defect, but now they had a more interesting theory: our whole body is constantly "trying to taste" the world around us. Yes, this conclusion sounds like madness, or some kind of horror movie script, but it may well be true.
Take, for example, the kidneys. Receptors that recognize smells were detected in small groups kidney cells called «macula densa». These areas regulate the rate of filtration of blood, and hence the rate of urine, but the presence in these areas of the above receptors suggests that they literally "sniff" the urine and "try it on taste", carried out in such a way similarity of chemical analysis.
Even our blood can "sniff". In one experiment, blood cells, scientists placed on one side of the chamber and particularly an aromatic compound that interacts with the olfactory receptors blood cells - on the other. And with enthusiasm (and perhaps with horror) we watched as the blood cells move closer to the source of the smell.
Now hold on, because now you will hear something even more strange.
You know what else has the "smell"? Sperm.
There is speculation that sperm uses his "olfactory receptors" to look for a female egg. Like a bloodhound.
2. synapses in our brain is 1,000 times more than the stars in our galaktike
For some time, researchers believed that the human brain about 100 billion neurons. This theory was debunked when they had a direct investigation, and found that this number is closer to 86 billion.
However, there are more synapses, the connections between neurons, which are connected together to form a huge network that is our mind.
The total number of synapses is staggering: 100000000000000.
This number is 1,000 times greater than the number of stars discovered in the Milky Way galaxy.
The brain performs 20 million billion operations per second, and compared to him even the most advanced computers look very, very pale. In 2013, Japanese experts in cooperation with the German tried to build a machine that could simulate the entire computing power that lies in the human skull. Using the power of the 82944 processor, the experts were able to achieve something that is comparable in strength to one second of our mind. To get to such a power, it took them 40 minutes.
And yet, here you are, reading this site, and your browser is open 16 more tabs with different entertainment sites on which you're going to go. This is about how to use the Large Hadron Collider in the kitchen as a toaster.
3. Your hearing is so sensitive that it can differentiate between temperaturu
Evolution has tried to modify his ears so as to ensure our survival in a world in which previously dominated the saber-toothed cats and mammoths huge.
First of all, it has a strange shape: it is assumed that all these strange folds, creases and folds in the other slot should help people to better determine which side of him sneaking up predator.
Did not surprised? And how about this: You can literally "hear the temperature." Yes, it turns out, too, are such phrases.
For the first time such a suggestion put forward by representatives of a British advertising company that once tried to find out: whether the subjects feel the difference between hot and cold tea poured into a glass, listening only to the sound pours a drink. The experimental results are striking: 96% of the test volunteers correctly identified the temperature of the drink is poured. It could not be a coincidence. Some believe that all this may be due to the different viscosity liquids poured. Molecules in cold liquids vary not so vigorously and better "glued" to one another while in the hot liquid are worn as mad. A super-our ears are designed so that they can hear how "lazy" molecules in a liquid.
4. Mucous your stomach twice a week is completely dissolved acid and recovering
This is a question that probably at least once asked each person: "Why our stomach does not digest itself»?
After the stomach, eventually, permanently it produces a deadly hydrochloric acid, which is even used for pickling steel. Of course, you would not like to see something like that happen inside your body. But why the stomach remains intact?
The fact that our stomach has a unique ability to regenerate. Here's how it works: in your stomach has special cells that produce protein-rich and viscous mucus to protect the stomach from acid, which it uses in the process of digestion. Once the acid has done its job, the cells of the stomach neutralize it with an alkaline bicarbonate and is excreted from the body.
But even his own super-goo is not enough to give the final acid resistance. The stomach is still digesting itself. That is why it carries out difficult work to heal itself, with it must go faster than dissolution. Gradually, the "spent" mucus layer in the stomach is completely replaced by the new, and it happens twice a week.
5. You can make cancer a thousand times during dnya
Cancer - the eternal curse of the human race. And all my life sitting on a diet of carrots and greens, but eventually your chances of cancer will be reduced to make the probability of 38% (women) and 43% (men). It is almost the same as if you just flip a coin.
And all because the cancer develops amazingly easy. This occurs when cells that are born and die, on average, once every few days, and are fixed accumulate mutations making it corrosive. This cell starts to divide at a breakneck pace, ignoring the natural mechanism. It turns into a murderer.
How often is this?
It is believed that each of the many trillions of cells in your body receives tens of thousands of potentially dangerous changes daily. Your body - both John McClane from the "Die Hard" desk tolerates strikes, but continues to damn hard work.
In other words, every day we can get cancer at least a thousand times.
But no need to worry. Special enzymes travel through our body, DNA for inspecting potentially dangerous mutations that can cause cancer. If somewhere there is a problem, and cell replication process turned its replication scheme upside down (yes, it happens sometimes), these incredible enzymes, assistants can detect the fault and release for her "patch" before it has time to grow in the deadly tumor.
Of course, this can not be 100% effective. Sometimes, it slips through the protective net, and then there is disease. But considering the entire volume of the potential of cancer, which prevents every day, we can confidently say that our body - amazing.
