No matter if you're a scientist (or a curious layperson), you can learn many fascinating facts regarding the human body. There are thousands, if not millions, of biological systems in the body. Each one has a unique purpose. It is a wonderful place. You can learn about the skeletal system, the circulatory system, and the digestive system, just to name a few.
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 make up the human microbial biome.
Teeth are part and parcel of the skeletal systems of the human body. An adult's set of teeth has approximately 32 teeth. Teeth are not considered as bones, but they make up part of the skeletal systems. The hardest substance in the human body is enamel.
The adult human heart beats around 36,500,000x a year. The average adult blood supply is around five liters. A person's bladder can store 16-24 ounces worth of urine. Most people draw their lung as one size. The adult human lungs have a surface area of 70 square meters.
The human body contains more than 600 skeletal muscles. Each muscle works in pairs. There are also muscles which pull in different directions. 20 tons of force is contained in the human body. The heart is its only muscle that does not fatigue. The eye is made up of 2 million different parts and can distinguish 10,000,000 colors.
25 million human cells are made every second. It generates enough heat to boil half a gallon of water in 30 minutes. It also produces heat for the digestion of food. This heat helps maintain the body's homeostasis. The heart can exert enough pressure to pump blood up to 30 feet.
There are 100,000 miles of blood vessels in the human body. The circulatory system consists of the heart, arteries and veins. It moves oxygen, carbon dioxide, and nutrients throughout the body. It also helps to eliminate waste from the body. There are two quarts of waste filtered out of the human body by the kidneys.
Human nose can detect 50,000 different smells. It also generates enough electricity that it can light a bulb. The human eye can see ultraviolet light.
The human brain is the biggest organ in the body. It houses 100 billion nerve cells. The adult brain has more oxygen use than the rest. Without oxygen, the brain can live for five to ten minutes. The adult human brain weighs three pounds. It consumes about 20% more oxygen than the rest of our bodies. It also has more nerve cells than the Encyclopedia Britannica. The brain generates more electricity per day than all other telephones worldwide.
The human body has over 500 different functions. Some of these functions include the ability to digest food and filter out waste. The liver is often called the "chemical factory" of the body.
FAQ
What is the most mysterious location on Earth?
Antarctica is the world's most mysterious place on Earth.
We find this place so fascinating. Because it's unlike any other place in the world.
It is isolated, remote, and very hard to visit. But there is more to this site than meets the eye.
You'll also find the strangest species of wildlife in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
Antarctica is named for no one. Others believe it means "land with ice". Others believe it comes out of Greek mythology.
Antarktis is the name Antarktis was given to an island in ancient Greece by Zeus' twin brothers. According to legend, one twin was born in winter. This is why the word "antarctic" was chosen.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would mean land turned away from the sun.
No matter the reason, Antarctica is a place that has always fascinated people.
It is the driest, windiest of all continents. Because it is too frigid, there are no trees, animals, or plants.
Yet, life is abundant in this frozen wilderness.
It is home to approximately 90 percent of all life on Earth. About 50% of the world's plant and animal species can be found here.
What is Antarctica? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large masses to form of ice which float high above the ground.
These glaciers are responsible for covering 80% of the continent. And they're growing larger every year.
The Antarctic ice has grown 60 feet so far since 1960.
If the melting goes on, the sea level may rise by as much as 200 feet. That could cause massive flooding around the globe.
Not everyone believes this is bad news. Some scientists suggest that global warming could actually be good for us. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
What are some dark secrets in Hollywood?
Hollywood is full of secret societies. Many secret societies are cult-like and follow rigid rules. Others are just clubs for people with common interests.
But there are also more nefarious organizations that control much of the industry. Companies such as the MPAA, which determines film ratings, or the RIAA (Recording Industry Association of America), that set music licensing fees, are examples of these.
Numerous unions, guilds, and associations represent actors, writers, producers, editors, and other creative professionals. Many of the major TV networks and movie studios are owned or controlled by large corporations.
It doesn't really matter how secretive an organization may appear, there is always someone who knows exactly what they do. We shouldn't fear these people.
Instead, we should embrace these facts. Because they provide us with information that helps us make better decisions.
These people tell us what movies and songs will succeed, and which books will sell best.
These help us to decide what we'll watch, read, listen, and buy.
We can trust their advice and we can ignore it if it contradicts our values.
They are more powerful than ever because we chose to ignore them. They become the ultimate arbiters of taste.
You are free to ignore their messages if that bothers you.
Now let's take a look at some lesser-known yet very real Hollywood secret society.
You'll see why they are so important.
Why are actors blacklisted?
When you're an actor, there's more rejection than when you're a writer. As an actor, it's likely that you will be rejected a lot. You will find someone who loves and accepts you eventually.
Actors have a lot of talent, so they can make a decent living almost anywhere. Actors aren't always interested in making a living. Actors love acting, and love telling stories. You'll be an actor if you love acting.
Sometimes, auditions are cancelled because you are either too young or too old for the job. Sometimes, you may lose an audition for a movie. It happens all too often.
Once you've been cast you might also be subject to criticism. People will tell you that you look terrible or shouldn't be wearing makeup. If you're lucky, you won't even hear negative comments.
Sometimes you'll be criticized because you're playing a character that isn't realistic or authentic. Maybe you play a gay man, and everyone thinks you're straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
You might be asked to change the sound of your voice. Sometimes they ask you to sound like either a boy or a girl. Most times, though, they want you to sound better.
These criticisms should be ignored. Actors often feel like they've failed if they're told they did something wrong. But the truth is that they haven't done anything wrong.
They didn't have the talent to make them famous. They don't always fit the bill, no matter how hard they try.
There are many reasons an actor might be blacklisted. Some people don't like actors. Others feel that actors are lazy. Still, others say that actors are cheaters.
It doesn't matter what reason it may be, you won’t be banned if you keep trying. There are many opportunities for you to find your role.
You'll succeed as long as you keep trying.
Is there any Hollywood blacklist for actors?
There is a Hollywood blacklist.
But the list isn't made public. We don't know the names. Here's why this matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. So they'd go out of business, which means that the studios would lose money. This would mean that they would cut back on movie production. That would reduce the opportunities for blacklisted filmmakers. This could lead to them going bankrupt.
This could eventually lead to more victims.
When someone tries making an Oscar winning movie they might be asked for a contract. This means that they can't publicly criticize their employer. This applies to any producer or director who wishes to be nominated.
Producers often pressure directors to cut scenes from their films. Directors threaten to abandon projects that don’t conform to their vision.
This is why Hollywood has a blacklist. If you are negative about your employer, you'll most likely go unemployed. It's not good for anyone.
Problem is, many people have been falsely charged. It's been a struggle to get their names cleared.
This kind of thing must stop before it can happen again. It is essential that everyone has the freedom to express their opinions.
Therefore, it is necessary to eliminate the Hollywood blacklist.

Hollywood scandals that shocked the globe
It's shocking to see someone make a name for themselves. It's even more frightening to see them fall from grace.
It is amazing to see how an industry handles its mistakes. Many celebrities have used alcohol and drugs in excess. Some even died young because of it.
It's worse when stars make public their problems, and then are ignored by everyone. We found ourselves in that situation last week.
Heath Ledger, after a long and successful professional career, finally gave in to his demons. He succumbed after taking too many prescription medications. After a brief struggle with death, he died.
His family and friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once thought to be one the greatest actors of all time. Two Academy Awards nominations were given to Heath for his role in Brokeback Mountain.
In addition to acting, Heath also wrote and directed films, including A Knight's Tale, Monster's Ball, and Iron Man 3.
Hollywood loved Heath, but he became too big for his britches. He started to use drugs and drink heavily. He ended up in rehab and became clean.
After he had gotten sober, he decided to make amends. He produced a documentary called Room 237 that documented the making process of The Shining. It was supposed to hit theaters this year. However, it won't until next year.
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. It would have been nice for him to have received some assistance before things spiraled outof control.
We hope Heath's story warns others who might think they can still have it all.
