There are many fascinating facts about human bodies, regardless of whether you're an expert or a layperson. 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 find out about the skeletal structure, the circulatory and digestive systems, to name just 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 were formed at the Big Bang 13 billion year ago. 39 trillion cells are estimated to make up the human microbial Biome.
Teeth are part of the skeletal system. A person's adult teeth can have approximately 32 teeth. Teeth are not considered as bones, but they make up part of the skeletal systems. The hardest substance in our body, enamel, makes up teeth.
Adult human hearts beat approximately 36,500,000x per 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.
There are more than 600 skeletal bones in the human body. Each muscle works in pairs. There are also muscles that pull in different directions. The human body contains 20 tons force. The heart is the only muscle that doesn't tire. The eye can distinguish 10 million colors and has 2 million parts.
The human body produces 25 million cells per second. It generates enough heat for boiling half a gallon (or more) of water in just 30 minutes. It produces heat that aids in digestion. This heat is used by the body to maintain homeostasis. The heart can exert enough pressure to pump blood up to 30 feet.
The human body is home to 100,000 miles of blood vessels. The circulatory system includes the heart, arteries veins, capillaries, and veins. It is responsible for moving oxygen, carbon dioxide, nutrients, and other substances throughout the body. It also eliminates waste from your body. There are two quarts of waste filtered out of the human body by the kidneys.
The human nose can distinguish between 50,000 smells. It can also produce enough electricity to light up a lightbulb. The human eye can sense ultraviolet light.
The human brain is the biggest organ in the body. It has 100 billion nerve cell. The adult brain consumes more oxygen than all other parts of the body. The brain can survive five to 10 minutes without oxygen. The adult human brain weighs three pounds. It takes 20% less oxygen than the rest. It also has more nerve cells than the Encyclopedia Britannica. The brain generates more electrical impulses each day than all the other telephones in the world.
Over 500 functions are part of the human body. These functions include digestion, filtering out waste and breathing. The liver is sometimes called the "chemical plant" of the body.
FAQ
How does the brain control the functions of your body?
The brain communicates with other organs to ensure their cooperation. Your body's functions are controlled by your brain. It tells you your stomach to digest food; your lungs to inhale air; and it tells you your arms and legs how to move.
Your brain is composed of billions and billions nerve cells, connected in groups called neurons. Action potentials are electrical signals that neurons send to one another. Each neuron has its own cell membrane around its nucleus. The cell membrane houses channels that allow ions, such as potassium and sodium, to enter and exit the cells. The electric charge that causes the neuron's fire is created by ion movement.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. As a result, second neuron fires as well.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.
Communication within the nervous system is possible thanks to neurotransmitters. They are also responsible for coordinating activity between various parts of the brain.
What is your most secretive community?
It may surprise you to hear the answer. It might even make you uncomfortable because it challenges our perception of reality and how we live. But there is a reason that this place exists. It isn't what you would expect.
The ancient Greeks called it the City of God. It was also called the City of Destruction in the Bible.
It's known in India as Kashi (Kashmir). It's also known as Novgorod in Russia.
But here in America, it goes by another name - The Town 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 tiny community disappeared without leaving any clues as to where it went or when. Some believe the earth swallowed them up. Some claim it was destroyed by a meteorite impact. Some believe that it was taken by aliens.
Despite what may have happened, the people who lived in this once-thriving area are confident that their town will not be lost forever. They had just moved to another town.
You can even track the disappearance of Zugspitz on a dedicated website.
So, where exactly did this town go? It's in Switzerland, actually!
Zugspitze is located on the border between Germany and Austria. Lake Zugspitze lies just above the summit of the mountain.
It has always fascinated me that so many towns have disappeared, yet some still remain. Is it possible that some towns disappear and others are preserved? I decided that I would investigate.
I wanted to learn more about mysteriously disappearing towns. What is the secret to a town's disappearance? How can one place vanish from existence?
It turned out that there are many theories about disappearing towns. One theory says that a town disappears when all the buildings are demolished. Another theory holds that the town simply relocates to another location. The third theory is that the town was never actually there.
Although theories may be a bit speculative, it is a fact that numerous towns have been destroyed by the elements. This video examines both the history and current status.
What are the darkest secrets of Hollywood?
Hollywood is filled with secret societies. Some are cult-like groups where members follow strict rules and rituals, while others are simply clubs for those who share common interests.
There are other nefarious entities that have a significant influence on 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.
Numerous unions and guilds also represent actors, directors, writers, producers, etc. Most major movie studios and television networks are owned by large corporations which own these various organizations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. However, we shouldn't fear them.
Instead, we should embrace and celebrate them. Because they offer us information that can help us make better decision.
They tell us what movies will likely succeed, what songs will be popular, and what books will best sell.
They are, in short, what help us choose what we will watch, read and listen too.
We can trust them so we can ignore their advice when it doesn't suit our taste.
Because we have chosen to ignore their power, they are even more powerful. They are the supreme arbiters of taste.
You can ignore them if they don't agree with you.
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.
