You can learn fascinating facts about your body whether you're a scientist, or just curious. There are thousands upon thousands of biological systems that make up the human body. Each system is designed for a specific task. The human body is a marvellous place. There are many things you can learn about the skeletal and circulatory systems, as well as the digestive system.
The human body is made up of about 7,000,000,000,000,000,000,000,000,000 (7-octillion) atoms. These atoms formed 13 billion years ago during the Big Bang. 39 trillion cells are estimated to make up the human microbial Biome.
Teeth are part of the skeletal system. Adult teeth have 32 teeth. Teeth are not considered bones, but they are part of the skeletal system. The hardest substance in our body, enamel, makes up teeth.
Adult human hearts beat approximately 36,500,000x per year. Average adult blood supply amounts to five liters. The adult bladder can hold 16-24oz of urine. Most people draw the same size lungs. A human adult lung has a surface area approximately 70 square metres.
There are over 600 skeletal muscles in the human body. Each muscle has two working parts. There are also muscles with different pulley directions. The human body contains 20 tons force. The heart is our only non-fatal muscle. The eye can distinguish 10 million colors and has 2 million parts.
25 million cells are created every second by the human body. It produces enough heat in 30 seconds to boil half a gallon worth of water. It produces heat that aids in digestion. This heat helps maintain the body's homeostasis. The heart can create enough pressure to send blood 30 feet away.
Human bodies have over 100,000 miles in blood vessels. The circulatory network is composed of the heart and arteries, veins and capillaries. It moves oxygen, carbon dioxide, and nutrients throughout the body. It also removes waste from the body. The kidneys filter out two quarters of the waste from the body.
The human nose is capable of recognizing 50,000 different scents. It also produces enough electricity for a lightbulb to be lit. The human eye is capable of detecting ultraviolet light.
The human brain is the largest organ in the human body. It contains 100 billion nerve cells. The adult brain requires more oxygen than any other part of the body. The brain can survive for up to 10 minutes without oxygen. The adult human brain weighs in at three pounds. It consumes about 20% more oxygen than the rest of our bodies. It also has more nerves cells than the Encyclopedia Britannica. The brain generates more electrical impulses each day than all the other telephones in the world.
There are over 500 functions in the human body. Some of these functions include the ability to digest food and filter out waste. The body's "chemical factory", the liver, is often called.
FAQ
What is the most secretive place in the world, and why?
It may surprise you to hear the answer. It could even make you uncomfortable, because it challenges how reality is perceived and lived. There is a reason this place exists and it's not as you might expect.
The ancient Greeks called it the City of God. According to the Bible, it was called the City of Destruction.
In India, it's called Kashi (Kashmir). It is called Novgorod (Russia).
Here in America, however, it is called The Village That Disappeared.
One small community in western New York State with 1,200 residents vanished without a trace. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
This little town disappeared, leaving no clues about where it went or when. Some say the earth swallowed it up. Others say it was destroyed in a meteorite collision. Some believe that it was taken by aliens.
Whatever happened, the residents of this once-thriving community are convinced that their town isn't gone forever. They had just relocated to another town.
You can even track the disappearance of Zugspitz on a dedicated website.
The question is, where did this place go? Well, it's in Switzerland!
Zugspitze is located on the border between Germany and Austria. The lake Lake Zugspitze is just beyond the mountain's summit.
It has always fascinated and astonished me to see how many towns have vanished but still exist. Is it possible that some towns disappear and others are preserved? I set out to find out.
I wanted more information about the mysterious disappearing of towns. What causes a town to disappear? How can one place become extinct?
It turns out that there are several theories about the phenomenon of vanishing towns. One theory says that a town disappears when all the buildings are demolished. Another theory suggests that the town simply moves somewhere else. Another theory suggests that the town has never existed.
No matter what theories you may have, there is no doubt that many towns across the globe were swallowed by the ground. This video examines the history and current status of these places.
Why are actors blacklisted?
As an actor, rejection is much more common than for writers. An actor will probably be rejected quite often. You will find someone who loves and accepts you eventually.
Actors are typically very talented and can earn a living virtually anywhere. However, most actors aren't interested in making money. They love acting, and they love telling stories. If you are an actor, you will most likely put yourself out there.
You might even go to auditions where you're told that you're too old, too young, or not right for the role. Or, you could lose out on a role in a movie. This happens all the time.
After you've been cast, there may be criticism. Some people will say that you look awful or shouldn't wear makeup. If you're lucky, you won't even hear negative comments.
Sometimes your character isn't real or authentic and you will be criticised. Perhaps you're a gay man who everyone believes is straight. You might play a tough woman, but she is very emotional.
Or maybe you're asked to change your voice. Sometimes they ask you to sound like either a boy or a girl. They want you to sound better most of the time.
To ignore criticisms is the best way to respond. Actors can feel like they have failed when they are told they did something wrong. But the truth is that they haven't done anything wrong.
They weren't born with a talent that made them famous. Sometimes, no matter what they do, they just don't fit the bill.
There are many reasons an actor might be blacklisted. Some people don't like actors. Some people think actors are lazy. Still, others say that actors are cheaters.
No matter what the reason, you won't be blacklisted if your persistence persists. There are plenty of jobs available and you'll find them.
Keep trying and you will eventually succeed.
What is the most interesting fact about the human body?
There are two eyes, two ears. Two nostrils. Four limbs. A mouth, nose and penis. You're correct, there are more than 50 parts in our bodies. But, one thing is missing. A heart.
The heart is a pump that circulates blood throughout your body. The blood moves through the veins. It transports oxygen and nutrients to your cells. It also removes carbon dioxide.
Each minute, the heart pumps 5 liters of blood. This amount is equivalent to an adult drinking 2-3 cups of coffee daily.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. Your heart beats nearly 100 times a minute while sleeping.
You can tell whether someone is healthy or unhealthy because of the color of their skin. The capillaries are tiny blood vessels that can be seen on the skin's surface. These vessels carry blood back to the heart from the large blood vessels beneath the skin. When blood flow is blocked, the skin turns blue or purple.
People with sickle cells lack red blood cell. Patients with sickle cell disease have their blood become sticky and harden, leading to severe illness.
To stop bleeding from a cut, you can apply a bandage to the wound. Blood must continue to flow to allow the wounds to heal properly. Doctors insert a needle into the injured area through the skin. This allows blood drainage from the injury area.
Doctors also insert tubes (catheters) into the artery near the site where the blood clot forms. This keeps the patient occupied until the clot is broken down naturally.
What is the most mysterious place on earth?
Antarctica is one of the most mysterious places on Earth.
Why do we find this place so intriguing? It is unlike any other place on Earth.
It is remote, isolated, and extremely difficult to visit. There is much more to this place than meets the eyes.
These wild animals are also found in this natural wonder.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some believe it is "land of the ice". Others believe it derives from Greek mythology.
Antarktis was an ancient Greek name that was given to the island where Zeus and his twin brothers, Zeus. According to legend, one twin was born in winter. Hence, the word antarctic.
Others believe that the name is a combination of the Greek words anti and tropos which mean against and turn. This would translate to land that is turned away from the sun.
Whatever the reason Antarctica has held a special fascination for people, it is undeniable.
It is the driest, windiest of all continents. Because it is too frigid, there are no trees, animals, or plants.
This frozen wasteland is still alive.
About 90 percent of all living things on Earth live here. You can find approximately half the world's species of animal and plant plants here.
What is the secret to Antarctica's unique environment? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large ice masses to rise above the ground.
These glaciers are responsible for covering 80% of the continent. They are growing in size every year.
The Antarctic ice has grown 60 feet so far since 1960.
The sea level could rise to 200 feet if the melting continues. That could cause massive flooding around the globe.
This is not necessarily bad news. Global warming may be beneficial for some scientists. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
Others warn that this theory sounds like something out of a science-fiction movie.

Hollywood scandals that shocked the world
There's nothing more shocking than watching someone become famous for the wrong reasons. But, it's equally shocking to watch them fall from the graces.
It's fascinating to see how industries react to their mistakes. Many celebrities have used alcohol and drugs in excess. Some even died young because of it.
But, the worst part? When those stars openly discuss their issues and are ignored by everyone. We were there last week.
Heath Ledger gave up after a long career that was successful. He died after succumbing to prescription drugs.
His family and close friends had difficulty accepting his death. The media took to him publically.
Heath was once thought to be one the greatest actors of all time. His performance in Brokeback Mountain earned him two Academy Awards nominations.
Heath not only acted, but also wrote and directed films including A Knight's Tale. Monster's Ball. Iron Man.
Hollywood loved Heath. However, he quickly grew too large. He began to drink heavily and took drugs. He ended up in rehab and became clean.
He wanted to make amends now that he was sober. So he made a documentary called "Room 237," which chronicled the making of The Shining. It was originally scheduled to release this year, but it won’t be available in theaters until next.
Heath was unsuccessful in his attempts to get back into Hollywood. Heath was in fact arrested twice on drug charges.
We don't believe Heath should have been allowed to go back into the entertainment industry. However, it would be nice if he could get some help before things spiral out of control.
We hope Heath's story will serve as a warning to others who may think they can still have everything.
