Weird facts about the human body are fascinating to learn. One example: A human adult's skeleton is replaced every ten year. It is composed of four blood groups and 206 bone. Two kidneys are also present. In fact, the human body is one of the most complicated bodies on earth.
Every ten years, the adult human skeleton is replaced.
The human skeleton goes through continuous remodeling and reconstruction throughout life. Bone repair and remodeling are largely performed by bone cells. The body replaces nearly 100 percent its bone tissue every year. Osteoblasts are bones cells. They break down bone tissue and make new bones. This is called bone remodeling. A bone density measurement measures the amount of bone mineral within a bone.
It has two lungs
Two lungs or lobes are located in the chest cavity. These organs exchange oxygen and remove carbon dioxide. Each lung is protected by a membrane known as a pleura. The main bronchus connects the pleura to the heart and the trachea. Pleural membranes are thin and flexible, and act as an air filter. They also allow air into the lungs via the nose or mouth.
It has two ears
Despite being similar, the human ears are quite different. The complex structure of the earlobe allows us to hear and walk. Men's ears are typically larger than women's ears. The average ear length measures 2.5 inches. The earlobe measures 0.74 in long and 0.77 in wide. According to research, the size and width of the ear lobes increase with age.
FAQ
What is the most secretive town in the world?
The answer may shock you. It may even make it uncomfortable, as it challenges our perceptions of reality and our lives. There is a reason this place exists and it's not as you might expect.
It was called the City of God by ancient Greeks. It was also called the City of Destruction in the Bible.
In India, it's called Kashi (Kashmir). It is called Novgorod (Russia).
But here in America, it goes by another name - The Town That Disappeared.
A small town in western New York State, with a population of 1,200, vanished without a trace. 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 tiny community disappeared without leaving any clues as to where it went or when. Some say the earth swallowed it up. Others believe it was destroyed by a meteorite. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
The residents of this once prosperous community believe that whatever happened, their town is not gone forever. They had just moved from one town to the other.
Even a website exists to help track down the disappearances of the lost city Zugspitz.
The question is, where did this place go? Well, it's in Switzerland!
Zugspitze is located on the border between Germany and Austria. A huge lake, Lake Zugspitze, is located just beyond the summit.
It's always fascinated me how so many towns disappear, yet others remain. Is it possible that some towns disappear and others are preserved? I decided to investigate.
I was curious about the disappearing towns. What causes a community to disappear? How can one place become extinct?
There are many theories regarding the phenomenon of towns disappearing. One theory holds that a town disappears if all its buildings are demolished. Another theory holds that the town simply relocates to another location. A third theory claims that the town never existed at all.
Although theories may be a bit speculative, it is a fact that numerous towns have been destroyed by the elements. This video examines the past and present status of these areas.
Which is the most mysterious spot on Earth?
Antarctica is the world's most mysterious place on Earth.
This is why we find it so captivating. Because it is unlike any place on Earth.
It is remote, isolated, and extremely difficult to visit. There is much more to this place than meets the eyes.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Some say it means "land on ice." Others believe it comes out of 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 of the twins was born in winter. Thus, the term antarctic.
Others believe the name was derived from the Greek words tropos, which means turn, and anti, meaning against. This would be land turned away form the sun.
Whatever the reason, Antarctica has always held a special fascination for people.
It is also the lowest, windiest continent, driest, and highest. It is too cold for trees, plants and animals.
And yet, this frozen wasteland is teeming with life.
It houses approximately 90% of all Earth's living organisms. It is home to approximately half of all world's animal and plant species.
What makes Antarctica so special? Here, water freezes into ice instead of evaporating into the air.
This causes large ice masses to rise above the ground.
These glaciers cover more than 80% of the continent. These glaciers are getting larger each year.
The Antarctic ice sheet has grown 60ft since 1960.
The sea level could rise to 200 feet if the melting continues. This could lead to massive flooding across the globe.
However, not all scientists believe this to be bad news. Some scientists suggest that global warming could actually be good for us. According to scientists, global warming could be good for us because the melting of the ice sheets will accelerate, which can lead to floods that release toxic chemicals into our soil and bodies.
Others warn that this theory sounds like something out of a science-fiction movie.
What dark secrets are there in Hollywood?
Hollywood is full of secret societies. There are secret societies that are more cult-like than others. They have members who follow specific rules and rituals. While some are clubs for those with similar interests, others are not.
Some of the most powerful organizations in the industry are even more dangerous. These include companies such as the MPAA (Motion Picture Association of America), which sets film ratings, and the RIAA (Recording Industry Association of America), which sets music licensing fees.
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. However, we shouldn't fear them.
Instead, we should embrace these facts. Because they can help us make better decisions.
They also tell us about the movies that are most likely to succeed and which songs are most popular.
They allow us to make informed decisions about what we buy, watch and listen to.
We can trust them so we can ignore their advice when it doesn't suit our taste.
They are more powerful than ever because we chose to ignore them. They are the ultimate arbiters and judges of taste.
You are free to ignore their messages if that bothers you.
Let's now look at some lesser-known, but still very real Hollywood secret organizations.
And see why they're so important.
Is there any Hollywood blacklist for actors?
There is a Hollywood blacklist.
But, the list has not been made public. The names are not known to us. But here's why it matters.
The secretive nature of the information is due to the fact that actors and directors on blacklist won't be in a position to find work. Thus, they would leave the industry and studios will lose money. It would mean they would reduce their expenditure on movies. That would reduce the opportunities for blacklisted filmmakers. This would make them bankrupt.
This could result in even 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. Producers and directors who want to be nominated are subject to the same restrictions.
Producers often pressure directors to cut scenes from their films. Directors threaten to abandon projects that don’t conform to their vision.
This is the reason there is a Hollywood blacklist. If you speak negatively about your employer, you will likely be fired. It's not good for anyone.
Problem is, many people have been falsely charged. It's been a struggle to get their names cleared.
We must stop this from happening again. Everyone should have the right to speak freely.
We need to get rid of Hollywood's blacklist.
