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. The human body can be described as a vast and complex wonderland. 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 were formed during the Big Bang 13 billion years ago. It is estimated that the microbial biome of the human body is 39 trillion cells.
Teeth are part and parcel of the skeletal systems of the human body. There are about 32 teeth on an adult's teeth. Although teeth aren't considered bones, they are part and parcel of the skeletal structure. Enamel, the hardest substance in the body, is what makes teeth.
The adult human heart beats about 36,500,000 times a year. The adult blood supply averages five liters. An adult bladder can hold between 16 and 24 ounces of urine. Most people draw their lungs as the same size. A human adult lung has a surface area approximately 70 square metres.
There are over 600 skeletal muscles in the human body. Each muscle is composed of two parts. There are also muscles that pull in different directions. The human body has 20 tons of force. The heart is its only muscle that does not fatigue. The human eye has 2 million working parts, and can differentiate 10 million colors.
25 million cells can be produced by the human body every second. 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 for maintaining homeostasis. The heart can create enough pressure to send blood 30 feet away.
The human body is home to 100,000 miles of blood vessels. The circulatory system consists of the heart, arteries and veins. It moves oxygen, nitrogen, and carbon dioxide throughout the body. It also filters out waste. The kidneys filter out two quarters of the waste from the body.
Human nose can detect 50,000 different smells. It also generates enough electricity to light a lightbulb. The human eye can see ultraviolet light.
The human brain is the largest organ in the human body. It is home to 100 billion nerve cells. The adult brain requires more oxygen than any other part of the body. Without oxygen, the brain can live for five to ten minutes. The adult human brain is 3 pounds in weight. It takes 20% less oxygen than the rest. It also has more nerves cells than the Encyclopedia Britannica. The brain generates more electrical impulses each day than all the other telephones in the world.
The human body has over 500 different functions. These functions include digestion, filtering out waste and breathing. The liver is often called the "chemical factory" of the body.
FAQ
Is there an Hollywood blacklist?
There is a Hollywood blacklist.
The list is not made public. As far as we know, the names aren't even known. Here's why this matters.
The reason for the secrecy is that the blacklisted actors and directors wouldn't be able to find jobs. Thus, they would leave the industry and studios will lose money. That would result in a reduction in spending on movies. Which would mean fewer opportunities for the blacklisted filmmakers. This could lead to them going bankrupt.
This could eventually lead to more victims.
In other words, if someone is trying to make an Oscar winning movie, they might have to sign a contract that says they won't speak openly against their employers. Producers and directors who want to be nominated are subject to the same restrictions.
It's no surprise that directors are often forced to take out scenes in their films by producers. Or directors threaten to walk out of projects that don’t match their vision.
This is why Hollywood has a blacklist. If you make negative comments about your employer, it's likely that you will be unemployed. This is not good news for anyone.
Many people have been wrongly accused. It's been a struggle to get their names cleared.
We must stop this from happening again. We need to ensure everyone has the right of expression.
We need to get rid of Hollywood's blacklist.
What are the darkest secrets of 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.
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.
Numerous unions and guilds also represent actors, directors, writers, producers, etc. Large corporations own most major studios and networks of television.
It is obvious that, no matter how secretive or obtuse a group appears, someone knows exactly what they do. But that doesn't mean we should fear them.
Instead, we should embrace them. Because they can help 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 become more powerful because we choose to ignore them. They are the ultimate arbiters and judges of taste.
You can ignore them if they don't agree with you.
Let's take a closer look at some of the less-known, yet still very real Hollywood secret clubs.
And see why they're so important.
How does the brain control the functions in your body?
The brain relays messages to other parts of the body to ensure their functionality. Everything in your body is controlled and managed by your brain. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Neurons communicate with each other by sending electrical signals called action potentials on axons. Every neuron has a cell wall around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. The neuron is lit by an electric charge created by the movement of ions.
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. In turn, the second neuron also fires.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds at the receptors of the post-synaptic Neuron and triggers its firing.
Communication within the nervous system is possible thanks to neurotransmitters. They also coordinate activity between different brain parts.
Which is the most mysterious spot on Earth?
Antarctica is home to the most mysterious and remote place on Earth.
Why is this place so amazing? Because it is unlike any other spot on Earth.
It is remote, isolated, and extremely difficult to visit. But there is more to this site than meets the eye.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some believe it means "land of ice." Others believe it derives from 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 twin was born in winter. Hence, the word antarctic.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would signify land turned away the sun.
Whatever the reason Antarctica has held a special fascination for people, it is undeniable.
It is the driest, windiest of all continents. There are no trees, plants, or animals here because it is too cold.
Yet, life is abundant in this frozen wilderness.
It houses approximately 90% of all Earth's living organisms. You can find approximately half the world's species of animal and plant plants here.
What is the secret to Antarctica's unique environment? Here, water freezes in ice rather that vaporizing into the atmosphere.
This causes large amounts of ice to float above ground.
These floating glaciers make up 80%. These glaciers are getting larger each year.
Since 1960, the Antarctic ice sheets has grown 60ft.
If the melting goes on, the sea level may rise by as much as 200 feet. This could lead worldwide flooding.
This does not mean that everyone is wrong. Some scientists claim that global warming could be good for us. They believe that global warming will lead to melting ice sheets faster and floods that can flush toxic chemicals out of our soils and bodies.
Others cautioned that this theory sounds too science fiction.
