Breaking the Speed Limit

Breaking the Speed Limit
Our bodies do not move as fast as other animals, the cheetah for example, but we can exceed 100 miles per hour with something; our sneezes. When we sneeze, we expel air from our nose and mouth at the whopping speed of 100 miles per hour. That is pretty fast considering that it is coming out of our face and many may wonder why we do not blow our nose clean off with that kind of force.

We Are Visual Beings

9=We Are Visual Beings
We are visual beings because of the amount of information we process through our eyes, rather than through other senses. While bats may process most of their information through their ears, we process 90 percent of all our information through our eyes. The other 10 percent of the information is processed by our other four senses of touch, taste, smell and sound.

Our Bodies Are Hot

Our Bodies Are Hot, Hot, Hot!
The human body is one big energy producing machine. When you look at a picture of the human body with infrared technology, all you see is radiating heat. That heat is generated within our bodies and it helps to keep us alive. In fact, the human body generates so much heat that in only 30 minutes, the average body gives off enough heat (throughout the entire body) to bring half a gallon of water to boil. That may not seem like much given you can boil water in only a few minutes on the stove, but remember that your body is boiling this water by doing nothing but what it does every day; keep you alive!

Nature’s Filter

Nature’s Filter
Your kidneys help to get rid of toxins from our bodies and without our kidneys, both of them, we would die. The reason for this is the amazing filter capacity of kidneys. Each kidney contains one million filters. This means your body has two million individual filters in it, which filter out 1.3 liters of blood per minute and expel 1.4 liters of urine per day!
Without this vitally important filtering, our bodies would quickly fill with toxins and we would soon find ourselves very sick and very close to death. This is why people whose kidneys have failed need to be hooked up to kidney dialysis machines.

We Grow Every Night

We Grow Every Night
Yes, that’s right, every single night your body grows by a little bit. It is estimated that the human body grows about one-third of an inch while you sleep because your cartilage discs are squeezed by the force of gravity when you are standing or sitting. So, when you wake up and start walking, your height shrinks back down to your normal height.

our Lungs, Bones and Nails!

Your Lungs, Bones and Nails!
Here are essentially three facts in one. First, your lungs are full of tiny blood vessels called capillaries. In both your lungs, there are 300,000 million capillaries and if you were to take all of these capillaries and lay them out end-to-end, they would stretch for 1,500 miles. Second, we can break our bones but our bones are actually quite strong. One block of bone the size of a matchbox can support the weight of nine tones, which is actually four times as much weight as concrete can hold. Third, your fingernails are constantly growing and if you lose a fingernail, it will take roughly half a year for the nail to grow back from the base to the tip.

Beware the Power of Stomach Acids

Beware the Power of Stomach Acids
Your stomach is a very powerful part of your body. The stomach acids that sit inside of our stomach are so strong that they can dissolve zinc. You would think that such a strong acid would eat through our body in seconds, but our stomach lining actually renews itself so fast that there is not enough time for the acid to eat through the lining. If it was not for this renewing capacity, we would have a large hole in our body within minutes.

Your Hair Is the Superman of the Body

3. Your Hair Is the Superman of the Body
When we say your hair is the Superman of the body, what we mean is that your hair is pretty much indestructible. Hair decays at an extremely slow rate and that means hair often stays around longer than most other parts of your body. In fact, mummies that date back thousands of years still have hair on their heads. Changes in climate, humidity and temperature can’t hurt your hair, and neither can many different varieties of acids and chemicals. The only real weakness your hair has is to fire, which is probably because your hair is made up of so much carbon.

Cool Facts

2.. The Death of Hundreds of Millions
Each minute, our body is dying, this is a fact. Each time 60 seconds has passed by; our body has lost 300,000,000 cells. Yep, that’s right, that many cells, which amount to the population of the United States, die in our bodies every single minute. While this may seem like a lot of dying cells, and you would think our bodies would decay within hours, there are more cells being born than dying in our bodies. Each day, 10 to 50 trillion (50,000,000,000,000) cells are replaced in our body.

Cool Facts

1. You Can Live Without Many of Your Internal OrgansMany of us think that if we were to lose one of our internal organs, we would die immediately, and while this is true for the heart, it is not so true for other internal organs. In fact, you can remove your spleen, one kidney, one lung, as well as 75 percent of your liver, 80 percent of your intestines and most of the organs located in your pelvis and groin area. That’s right, all of those organs can disappear and you will still be functioning. You may not function so well, and you may not live for as long as you hoped, but yes, you can live without those organs.

Interesting Facts About . . .
The Human Body


In the average adult, the skin covers 12-20 square feet and accounts for 12% of body weight.b


There are more than 600 individual skeletal muscles in the human body.c


An adult skeleton has 213 bones.a


Cartilage is one of the few tissues that grows throughout life. Between ages 30 and 70, a nose might grow half an inch, and the ears grow about a quarter of an inch.e


A newborn's skull contains gaps between its bony plates. In an adult, the jagged plates interlock tightly like a jigsaw puzzle.a


The average human head has about 100,000 hairs.c


As a person ages, the diameter of each hair on the head shrinks. Hair is thickest in the early 20s, but by age 70, it can be as fine as a baby's. Aging also causes hair to grow where it is not wanted, such as in the nose and ears, and to fall out where it is desired.e


Hundreds of billions of neurons carry electrical signals that control the body from the brain and the spinal cord.c


After sustaining trauma to the brain—such as an injury, stroke, or infection—some people develop “alien hand syndrome,” a condition where the victim can feel sensation in the hand, but has no control over movement and does not sense the hand as a part of the body, as if it belonged to an alien being.d


The Greek philosopher Aristotle believed that the brain exists mainly to help cool the spirit. It is now known that the brain controls nearly every function of the body and mind.c


When the pituitary gland malfunctions, it can boost or reduce the amount of growth hormone in a growing child's body, resulting in gigantism or dwarfism.a


The senses are highly attuned to our world, but they have limits. For example, humans cannot see in the ultraviolet spectrum as bees do, nor can they differentiate between the hundreds of millions of odors that a bloodhound can.c


The appendix has no function in modern humans. It is believed to have been part of the digestive system in our primitive ancestors.b


Humans smell “in stereo.” Scent signals from each nostril travel to different regions in the brain. This may help a person determine the direction the odor is coming from.c


The skin contains approximately 640,000 sense receptors, scattered unevenly over the body's surface. These receptors are most abundant in the ridges of the fingertips, in the lips, at the tip of the tongue, in the palms, on the soles of the feet, and in the genitals.e


An estimated five million olfactory receptors are clustered in the membrane at the upper part of our nasal passages. These receptors help us distinguish among thousands of different odors.e


There are about 9,000 taste buds on the surface of the tongue, in the throat, and on the roof of the mouth.b 


Taste buds contain chemoreceptors that respond to chemicals from food and other substances that are dissolved by the saliva in the mouth.e


Humans produce about 10,000 gallons of saliva in a lifetime. Saliva is required for taste—until food is dissolved by saliva, we cannot taste it.b


Hearing is one of the less acute senses in humans, compared to the many other animals which can detect sound at much higher and lower frequency than humans can.c


The lens of the eye thickens as a person ages, causing many middle-aged people to need glasses


As humans grow older, the lens in the eye grows thicker. This is why people who once had perfect vision often need glasses in their 40s.c


An adult human body contains approximately 100 trillion cells.e


The body carries about 25 trillion red blood cells (erythrocytes), the most abundant cells in the body. Red blood cells make up about 45% of blood's volume.e


Every hour, about 180 million newly formed red blood cells enter the bloodstream. Red blood cells are basically shells. Before being released from the bone marrow, most of a red blood cell's internal structure is ejected, creating a disc-shaped balloon that is ideal for carrying oxygen and a small amount of the body's carbon dioxide.c


White blood cells, or leukocytes, make up about 1% of blood. This number can double within a day when a body responds to infection.c


The circulatory system of arteries, veins, and capillaries is about 60,000 miles long.e


The heart beats more than 2.5 billion times in an average lifetime.b


Unlike other muscles, the heart muscle contracts without stimulus from the nervous system. Signals for the heart to beat come from the sinoatrial node near the top of the right atrium.c


In a healthy adult, the small intestine can range between 18 and 23 feet long, about four times longer than the person is tall.b About 90% of the body's nutrients are absorbed into the bloodstream in the small intestine.c


At about five feet in length, the large intestine is shorter than the small intestine. However, it is more spacious so it can store and process material that will be eliminated.c


There are approximately 400 feet of seminiferous tubules in the testes of a human male.c This is where sperm is stored until an ejaculation releases 200 million to 500 million sperm, each of which is capable of fertilizing an egg.e


During ovulation, the number of white blood cells in the cervical mucus drops dramatically. If it did not, the white blood cells would destroy all foreign bodies, including sperm.e


Unlike other cells, which contain an individual's full DNA, the egg and sperm each contain only half of the DNA required to create a new human. Both halves must be combined for humans to reproduce.g





A good diet helps a child's brain develop properly


Proper diet is critical for brain development in children. The brains of children who have died of malnutrition during the first year of life have fewer brain cells and an overall smaller size than the brains of healthy children.f


DNA, the basic building block of life, is a long molecule containing four chemical bases: adenine (A), guanine (G), thymine (T), and cytosine (C).g


The human genome—half the DNA contents of a single nucleus—contains about 31 billion base pairs: 31,000,000,000 A's, G's, T's, and C's.g


Six billion steps of DNA are contained in a single cell. This DNA can be stretched six feet, but it is coiled up in the cell's nucleus, which measures only 1/2500 of an inch in diameter.e


The maximum length of a mammal's life is generally related to its size. Thus, a man's lifespan should be somewhere between that of a goat and a horse, between 10 and 30 years. However, humans have developed ways to protect themselves from predators and disease, increasing their average lifespan to 74.7 years in the United States.e

Amazing Facts Of Body

These are the fifteen most wonderful things about our bodies that, hopefully, are news to most of our readers! So, onwards:
1. The stomach’s digestive acids are strong enough to dissolve zinc. Fortunately for us, the cells in the stomach lining renew so quickly that the acids don’t have time to dissolve it.


2. The lungs contain over 300,000 million capillaries (tiny blood vessels). If they were laid end to end, they would stretch 2400km (1500 miles).


3. A mans testicles manufacture 10 million new sperm cells each day – enough that he could repopulate the entire planet in only 6 months!


4. Human bone is as strong as granite in supporting weight. A block of bone the size of a matchbox can support 9 tonnes – that is four times as much as concrete can support.


5. Each finger and toenail takes six months to grow from base to tip.
6. The largest organ in the body is the skin. In an adult man it covers about 1.9m2 (20sq ft). The skin constantly flakes away – in a lifetime each person sheds around 18kg (40 lb) of skin.


7. When you sleep, you grow by about 8mm (0.3in). The next day you shrink back to your former height. The reason is that your cartilage discs are squeezed like sponges by the force of gravity when you stand or sit.
8. The average person in the West eats 50 tonnes of food and drinks 50,000 liters (11,000 gallons) of liquid during his life.


9. Each kidney contains 1 million individual filters. They filter an average of around 1.3 liters (2.2 pints) of blood per minute, and expel up to 1.4 liters (2.5 pints) a day of urine.

10. The focusing muscles of the eyes move around 100,000 times a day. To give your leg muscles the same workout, you would need to walk 80km (50 miles) every day.


11. In 30 minutes, the average body gives off enough heat (combined) to bring a half gallon of water to boil.


12. A single human blood cell takes only 60 seconds to make a complete circuit of the body.


13. A foreskin, the size of a postage stamp, from circumcised babies take only 21 days to grow skin that can cover three (3) basketball courts. Amazing isn’t it. Thanks to science. The laboratory-grown skin is used in treating burn patients.


14. The eyes receive approximately 90 percent of all our information, making us basically visual creatures.


15. The female ovaries contain nearly half-a-million egg cells, yet only 400 or so will ever get the opportunity to create a new life.
