The human body is an incredibly complex and complicated system that still baffles doctors and scientists on a regular basis, despite thousands of years of medical knowledge. As a result, there should be no surprise that even on parts of the body and the functions with which we deal every day, fraught with strange and unexpected facts and explanations. 100 Here the strangest and most interesting facts about the human body.

Interesting facts about the brain

The brain is the most complex and least understood part of the human anatomy. It is unrealistic a lot of what we do not know, but here are some interesting facts that we already know:

1. Nerve impulses to and from the brain travel at incredible speed - 170 miles per hour.

But few of us know how and why we react so quickly to what is happening around us? How is your finger, you hurt, it hurts right now? And this is connected with the super-fast movements of nerve impulses from the brain to the rest of your body, and vice versa, causing your reaction as efficiently as possible, and speed as a powerful sports car.

2. The brain consumes the same amount of energy as 10 - watt light bulb.

Cartoons, where the image appears light bulb over his head when a thought comes to mind of the character, in fact, not so far from the truth. Your brain generates as much energy as a small light bulb, and it's happening, even while you sleep!

3. The human brain cells can hold five times more information than any encyclopedia.

Scientists have yet to determine the final amount, but in the brain capacity electronic conditions are believed to 3 or even 1,000 terabytes. National Archives of the UK, with more than 900 years of history, which takes up to 70 terabytes, making your brain's memory is pretty darn impressive.

Hair and nails

Although they are not living part of your body, most people spend a lot of time caring for the hair and nails. So, next time when you will be directed to a haircut or manicure, think about this fact.

11. Facial hair grows faster than any other hair on the body.

If you have the stubble on his face, probably quite familiar with this fact. In fact, if the average person would never shave his beard, it would grow more than 30 feet during his lifetime (it is longer than the killer whale).

12. Every day the average person loses 60-100 strands of hair.

If you are already bald, then you have a good chance he would not give in to this pattern. Well, if not, your hair loss will vary according to the season, pregnancy, illness, diet and age.

13. A woman's hair thickness is about half the diameter of the hair of a man.

While it may seem strange, it should not be too surprising for many women in fact around less. Hair diameter also varies by race.

14. One human hair can withstand a 3.5 oz.

That is a fact, just one thread in the case of the use of hundreds of thousands of hairs that are normally present in the human mind makes the tale of Rapunzel much more plausible.

We do not always like to talk about it, but everyone has to do with bodily functions on a daily basis. Here are some interesting facts about the involuntary and sometimes unpleasant actions of our bodies.

We sneeze at a speed of 100 miles / h.

Here's a good reason why you can not keep your eyes open when sneezing, (correction, if you keep your hands forever, then we can sneeze with his eyes open, I already wrote about it, and "MythBusters" even showed :)). Sneezing flies out of your body at a speed close to 100 miles / h. This, of course, a good reason to cover your mouth when sneezing.

Earwax is essential for a healthy ear.

While many people find earwax, something disgusting, it really is a very important part of the defense system of your ear. It protects the delicate inner ear from bacteria, fungi, insects and even dirt. It also cleans and lubricates the ear canal.

Cough microbes rolls at a speed of about 60 miles / hr.

cold viruses constantly spread in such a way around the office or classroom, during cold and flu season. Spraying during coughing occurs far and wide, which is not surprising. Another reason to cover your mouth.

Women blink twice as often as men.

It is so much flicker every day what you imagine is difficult. The average person blinks about 13 times per minute. Although we do not notice it.

A full bladder is roughly the size of the ball.

It is no wonder that you have to run to the bathroom when you feel the call of the ancestors. The average capacity of the bladder about 400-800 ml, but most people feel the desire to get rid of excess fluid well before reaching the maximum numbers.

About 75% of human waste of water.

Most commonly thought that the whole thing in urine, since it is the main part of the liquid human waste, but the truth is that what we think of solid waste in fact - also mostly water. You should be appreciate that the majority of the waste is sufficiently filled with water, as otherwise would be chronic constipation, which is very painful.

500,000 sweat glands on the feet can not produce more than a pint of sweat a day.

But we, and half a liter is enough :) that make shoes become ominous. In addition, men tend to be much more active sweat glands than women.

During your life, you will produce enough saliva to fill two swimming pools.
