No matter if you're a scientist (or a curious layperson), you can learn many fascinating facts regarding the human body. There are thousands of biological systems in the human body, and each is designed to perform a specific task. It is a wonderful place. The skeletal system, circulatory system, digestive system are just a few of the many topics you can study.
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. The human body's microbial biome is believed to be 39 trillion cells.
Teeth make up the skeletal system of the body. A person's adult teeth can have approximately 32 teeth. Teeth are not considered to be bones but are part of the bone system. The hardest substance in the human body is enamel.
The adult human heart beats about 36,500,000 times a year. The adult blood supply averages five liters. The adult bladder can hold 16-24 ounces urine. Most people draw their lungs in the same way. The adult human lungs have a surface area of 70 square meters.
More than 600 skeletal muscle cells make up the human body. Each muscle is composed of two parts. There are also muscles with different pulley directions. The human body can produce 20 tonnes of force. 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 cells are produced every second in the human body. It produces enough heat in 30 seconds to boil half a gallon worth of water. It also produces heat that is useful for digestion. This heat is used by the body to maintain homeostasis. The heart can create enough pressure to send blood 30 feet away.
There are 100,000 miles of blood vessels in the human body. The circulatory system is made up of the heart, arteries, veins, and capillaries. It circulates oxygen, carbon dioxide and nutrients throughout the body. It also helps to eliminate waste from the body. The kidneys filter out two quarters of the waste from the body.
The human nose can distinguish between 50,000 smells. It can also produce enough electricity to light up a lightbulb. The human eye can detect ultraviolet light.
The brain is the largest organ of the body. It contains 100 billion nerve cells. The adult brain needs more oxygen than other parts of your body. The brain can survive for up to 10 minutes without oxygen. The average adult brain is 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.
Over 500 functions are part of the human body. Some of these functions are digestion, filtering, and breathing. The liver is often called the "chemical factory" of the body.
FAQ
Do you wonder how much trash is produced each day across the globe?
According to the United Nations, the average person produces over 2.5 pounds of daily waste.That adds up to over 25 billion pounds of garbage per year!
Many of this trash ends in landfill dumps, or incinerators. But what happens if those dumpsters are full? Where does all that rubbish go?Well, most of it gets shipped out of the country. It is then dumped in other countries, where it pollutes their ecosystems.But now, thanks to the work of one man, we know exactly where all this trash goes. Mike Sexton is his nickname. He owns a company called Waste Watchers. He spends his time watching trucks hauling trash around North America. Then he reports back to us about what happens next.
Sexton stated that he finds the job very satisfying. CNN interviewed Sexton and said that he has a lot of fun. "We'll be following these big rigs through town. "Sexton began following truckers almost 20 year ago.
He stated that he fell in love with the product.
Sexton's favorite story was about a driver who stopped at an abandoned gas station in Los Angeles. Sexton said that the man was searching for a place to store his stuff. "He drove down the road and saw this building. He pulled over and went in. "There were two huge roll-off containers there filled with stuff. The guy took everything out and started filling up the truck again. "Then he looked at the place and decided to unload everything. There were old tires and rags, furniture pieces, mattresses, mattresses and boxes. "It was just a total mess. But it had been cleaned out before he came along. There wasn’t trash everywhere."
What is the explanation? This particular spot used to be a recycling center. People would drive there to recycle their trash. Sexton explained that they would bring household items and take them to the building. Then, after they were done, they would empty the containers.
You might see this happen hundreds of times a day. This can happen hundreds of times a week.Eventually, the truck becomes so overloaded with junk that it stops running. The truck eventually stops running and the owner decides that it is time to get rid of the vehicle.
Trash, however, isn't the only problem facing our planet.As you may have noticed, things are getting worse.According to experts, pollution levels have risen dramatically in recent years.More than half of all water bodies on Earth are polluted.Pollution from industrial chemicals has increased by more than 30 percent since 1980.Even the air we breathe is becoming increasingly toxic.A study by the World Health Organization found that the average person inhales around 100 million particles daily.
These tiny plastic particles make up the majority of the particles. Some end up in incinerators or landfills. Some of these plastics end up in rivers or oceans.
Experts warn that if there is no change, the world could soon be facing a food shortage. One expert said, "If we keep going as we are going, we're never going to make it," but most people don’t seem concerned.
What is the most mysterious area on earth?
Antarctica is one of the most mysterious places on Earth.
What is it that makes this place so interesting? Because it's unlike any other place in the world.
It is remote, isolated, and extremely difficult to visit. This site has more to it than meets your 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
No one knows exactly why Antarctica was named Antarctica. Some say it means "land on ice." Others believe it comes from Greek mythology.
Antarktis, the Greek name for the island on which Zeus' twin brothers were conceived, was used in ancient Greece. According to one source, one of the twins was conceived 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 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 so cold, there aren't any trees, plants or animals.
Yet, life is abundant in this frozen wilderness.
About 90 percent of all living things on Earth live here. It is home to approximately half of all world's animal and plant species.
What makes Antarctica so special? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large amounts of ice to float above ground.
These floating glaciers cover over 80%. They continue to grow in size each year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
The sea level could rise to 200 feet if the melting continues. That could cause massive flooding around the globe.
However, not all scientists believe this to be bad news. Some scientists think global warming might be beneficial. 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.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
Is there a Hollywood blacklist.
There is an Hollywood blacklist.
However, the list isn’t public. The names are not known to us. It matters because of this.
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. This would result in studios losing money as the actors and directors would have to go out on their own. They would also cut back on their spending on movies. This would lead to fewer opportunities and less money for blacklisted directors. This would make them bankrupt.
This could result in even more victims.
In short, when someone tries to make an oscar winning movie, they might be asked to sign a contract saying they won't speak publicly against their employers. The same goes for any director or producer who wants to get nominated for an award.
That's why you hear stories about how producers pressure directors to remove scenes from their films. Or how directors threaten to walk away from projects that don't fit their vision.
This is why there is a Hollywood blacklist. You'll likely become unemployed if you say bad things about your employer. That's bad for everyone.
It is not uncommon for people to be falsely accused. They've had the toil to clear their name.
We must stop this from happening again. Everybody should be able to freely express themselves.
Also, we must take down the Hollywood blacklist.
What dark secrets can Hollywood keep from you?
Hollywood is filled 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.
But there are also more nefarious organizations that control much of the industry. These include companies like the MPAA ("Motion Picture Association of America"), which determines film ratings. The RIAA ("Recording Industry Association of America") sets music licensing fees.
Many unions and guilds represent actors, directors writers, producers, and others. Most major movie studios and television networks are owned by large corporations which own these various organizations.
The fact is that regardless of how secretive any group may be, someone somewhere knows exactly who they are. But we don't have to fear them.
Instead, embrace them. Because they provide us with information that helps us make better decisions.
These experts tell us which movies are most likely to succeed, which songs will be in demand, and what books will sell the best.
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.
And because we've chosen to ignore them, they become even more powerful. They are the ultimate arbiters and judges of taste.
If you don't like their words, you can choose to ignore them.
Let's now take a look into some lesser-known but very real Hollywood secret societies.
And you'll understand why they're so crucial.
