Weird facts about the human body are fascinating to learn. For example, an adult human's skeleton replaces itself every ten years. It contains four blood groups, and 206 bones. There are two kidneys. The human body is among the most complicated on Earth.
The adult human skeleton changes every ten year
Throughout adulthood, the human skeleton undergoes continuous remodeling and rebuilding. Bone remodeling and repair is a key function of bone cells. Nearly 100 percent of bone tissue in a person's body will be replaced over the course of their lives. Bone cells are called osteoblasts, and they break down old bones and form new ones in their place. This process is called bone remodeling. The bone density measurement is used to measure the amount bone mineral in a given bone.
It has two lungs
The chest cavity houses two lungs. These organs are responsible to exchange air and remove carbon dioxide. Each lung is covered by a membrane, called a "pleura", which is connected to both the heart (and trachea) by the mainbronchus. The pleural membranes provide air filtration. They are thin, flexible, and light. They also allow air in the lungs to flow through the nose, mouth, and nose.
It has two ears
Despite the similarities between them, human ears can be quite different in terms of their size, shape and color. The complex network of structures in the earlobe allow us to hear, see, and move. The ears of men are generally larger than the ears of women. The average ear length is 2.5 inches, and the ear lobe is 0.74 inches long and 0.77 inches wide. According to research, the size and width of the ear lobes increase with age.
FAQ
What dark secrets can Hollywood keep from you?
Hollywood is full of secret societies. There are many secret societies in Hollywood. Some are cult-like, where members adhere to strict rules and rituals. Others are clubs for people who share similar interests.
Some of the most powerful organizations in the industry are even more dangerous. There are companies like the MPAA (Motion Picture Association of America), who sets film ratings and the RIAA, which sets music licensing fees.
Numerous unions and guilds also represent actors, directors, writers, producers, etc. Many of the major TV networks and movie studios are owned or controlled by large corporations.
The point is that no matter how secretive any group may seem, someone somewhere knows exactly what they do. We shouldn't fear these people.
Instead, we should embrace them. Because they offer us information that can help us make better decision.
They also tell us about the movies that are most likely to succeed and which songs are most popular.
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 become more powerful because we choose 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.
And you'll understand why they're so crucial.
What is your most secretive community?
The answer may shock you. This may make you feel uncomfortable as it challenges your perception of reality and the way we live. But there is an explanation for why this place exists, and it's not what you would expect.
It was also called the City of God in ancient Greek. It was also called the City of Destruction in the Bible.
In India, it's called Kashi (Kashmir). It's known in Russia as Novgorod.
Here in America, however, it is called The Village That Disappeared.
One small New York State town with just 1,200 people vanished. It was abandoned without any remains, including no bodies, cars, or houses. The only thing that survived was a road sign, which pointed to its former location.
This little town disappeared, leaving no clues about where it went or when. Some say the earth swallowed it up. Others claim that a meteorite hit destroyed it. Some believe that it was taken by aliens.
The residents of this once prosperous community believe that whatever happened, their town is not gone forever. They had just relocated to another town.
You can even track the disappearance of Zugspitz on a dedicated website.
Then, where is it? Well, it's in Switzerland!
Zugspitze is located on the border between Germany and Austria. Just beyond the summit of the mountain is a huge lake called Lake Zugspitze.
It has always fascinated my that so many towns have disappeared but others still exist. Why do some disappear while others survive? I decided that I would investigate.
I wanted to learn more about mysteriously disappearing towns. What causes a community to disappear? How can one place vanish from existence?
It turns out that there are several theories about the phenomenon of vanishing towns. One theory holds that a town disappears if all its buildings are demolished. Another theory states that the town simply moves to another location. A third theory states that the town didn't exist at all.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video examines both the history and current status.
What is the most surprising fact about your 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 which circulates blood throughout the body. The blood flows through the veins and arteries to carry oxygen and nutrients to the cells.
Each minute, the heart pumps approximately 5 liters. This is equivalent to an adult consuming 2-3 cups of coffee per day.
Blood flows through the heart 24 hours a day, 365 days a year. Your heart beats nearly 100 times a minute while sleeping.
The color of someone's skin can tell if they are healthy or not. Looking closely at the skin's surface, you can see tiny blood vessels called capillaries. These vessels carry blood away to the heart via the large blood vessels. When blood flow is blocked, the skin turns blue or purple.
People suffering from sickle cell disease have no red blood cells. Their blood becomes sticky and hardens, causing them to become very ill.
To stop bleeding from a cut, you can apply a bandage to the wound. The wound must remain open for blood to flow properly. Doctors place a needle in the wound and insert it through the skin. This allows blood flow to the area that has been injured.
A doctor can also insert tubes (catheters), into an artery in the vicinity of where blood clots form. This keeps patients alive until the clot has broken up naturally.
Why do actors end up on the blacklist?
Actors are more likely to be rejected than writers. You will likely be rejected many times if you are an actor. It doesn't matter, because you will eventually find someone you love.
Actors are often very talented and can make a living anywhere. However, most actors aren't interested in making money. Actors enjoy acting and telling stories. You'll be an actor if you love acting.
Even worse, you might be told you are too young or too old to play the part. Or, you could lose out on a role in a movie. It happens all the times.
However, once you have been cast, it is possible to face 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 your character isn't real or authentic and you will be criticised. Perhaps you play a homosexual man and everyone thinks that you're straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
Or maybe you're asked to change your voice. Sometimes they ask you to sound like either a boy or a girl. They usually want you sound better.
These criticisms should be ignored. Actors often feel like they've failed if they're told they did something wrong. However, they aren't doing anything wrong.
They didn't have the talent to make them famous. They may not fit the bill sometimes, no mater how hard they try.
There are many reasons an actor might be blacklisted. Some people don't like actors. Others think actors can be lazy. Others still believe that actors cheat.
It doesn't matter what reason it may be, you won’t be banned if you keep trying. There are many roles available, and you will find them.
As long as you keep trying, you'll eventually succeed.
