Surprisingly, in a dream, our brain is working less. and often more than during daytime active lifestyle
Scientists say that the more a person IQ, the more he sees dreams

The total area of our lungs (all tiny bubbles - the alveoli) is comparable to the area of a tennis court
Heart rate in women on average lower than men, due to the lower body weight, and consequently, a smaller volume of blood, in need of "pumping"
The liver - one of the most difficult and loaded organs in our body. The number of functions it reaches several hundreds, including, for example, bile production, utilization of erythrocyte, the synthesis of the set of proteins and detoxification
The size of the heart reaches two stacked fists and the diameter of the largest vessel - the aorta is comparable to the diameter of a garden hose watering
The left lung is slightly smaller than the right due to the fact that we must make room for the heart
The human body is made with a large margin of excess reliability - people survive if it remove the stomach, spleen, three-quarters of the liver, 80% of the intestine, one kidney, one lung, as well as almost all the organs of the pelvic and groin area. Of course, a pleasant kind of life can not be named, but the removal of these organs is not deadly
The functions of the body
The air exhaled during sneezing, moving at a speed exceeding 160 kilometers per hour.
The same air during coughing spreads at a rate of slightly less - 100 kilometers per hour
Some people sneeze from bright light (I - too)
Women blink twice as often as men
Filling volume of the bladder is an average of 400 milliliters, although some people are able to "endure" to a volume of one liter
Approximately 75% of all human feces comprises water
On foot legs we are half a million sweat glands in the grid can allocate up to half a liter of sweat
Over a lifetime, we have released in the mouth so much saliva that it is possible to fill two swimming pools
An adult day break wind around 14 times, even if sure does not do so. Otherwise, they accumulate in the stomach and cause pain
Earwax - is not just an unfortunate misunderstanding. It lubricates and cleans the ear canal, as well as protects the delicate internal auditory organs from bacteria, fungi and insects
Reproduction
There are up to more than 120,000,000 sexual acts, that is, every day, about 4% of the world's population have sex. Not surprisingly, the Earth's population rapidly increased
The largest human cell - female egg, with a diameter of about a millimeter and can be seen with the naked eye. The smallest cells - the sperm, which is only slightly larger than the size of the cell nucleus
Your teeth have started to grow even six months before the birth. More precisely, begin to form special dental tubercles, which later become the teeth
Most babies are born with blue eyes because of the presence of these substances melanin. Under the action of ultraviolet light it decomposes and begins to "exude" real eye color

The strongest bone in the human body - jaw
To make a step, our body 200 engages muscles. And there are steps we make every day about 10 thousand ...
The only organ in the body that can not be restored - the teeth. The outer part of the tooth is the enamel, that is non-living tissue and can not regenerate itself, giving the work the dentist
Bone stronger some steel grades. Of course, the bone is more fragile, but if you take the same weight of steel, the bone is stronger
Of the 206 bones in our body is in pieces 52 feet
Through a microscope
32 million bacteria inhabit every inch of our body
Skin person updated on average every 27 days
Every moment in our body cells die 3,000,000,000
Every hour we have shed 600,000 particles of skin
Every day in the adult human body is made 300,000,000,000 new cells
The imprint of the language, like a fingerprint, is unique for each person
In our body enough iron to make a nail desyatisantimetrovyh
Our lips have intense red color due to the large number of capillaries that are close to the skin surface. Typically in these blood rich in oxygen, because of it has a red color. When we are cold, blood vessels and reduced oxygen saturation decreases, which leads to the blueness of the skin of the lips (and not only)
Miscellaneous
