There are many fascinating facts about human bodies, regardless of whether you're an expert or a layperson. There are thousands upon thousands of biological systems that make up the human body. Each system is designed for a specific task. The human body is a marvellous 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 created during the Big Bang 13 million years ago. 39 trillion cells are estimated to make up the human microbial Biome.
Teeth make up the skeletal system of the body. An adult's set of teeth has approximately 32 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 around 36,500,000x a year. Adult blood supply averages around five liters. A person's bladder can store 16-24 ounces worth of urine. Most people draw their lungs as the same size. The surface area for adult human lungs measures 70 square metres.
More than 600 skeletal muscles make up the human body. Each muscle works in pairs. There are also muscles that pull differently. The human body has 20 tons of force. The only muscle in the body that does not tire is the heart. The eye can distinguish 10 million colors and has 2 million parts.
25 million cells are created every second by the human body. It generates enough heat to boil half a gallon of water in 30 minutes. It produces heat that aids in digestion. This heat is used to maintain body homeostasis. The heart can generate enough pressure to squirt blood 30 feet.
The human body has 100,000 miles of blood vessels. The circulatory system is made up of the heart, arteries, veins, and capillaries. It moves oxygen, nitrogen, and carbon dioxide throughout the body. It also filters out waste. There are two quarts of waste filtered out of the human body by the kidneys.
The human nose is capable of recognizing 50,000 different scents. It also produces enough electricity to light one lightbulb. The human eye can sense ultraviolet light.
The largest organ in our body is the brain. It is home to 100 billion nerve cells. The adult brain uses more oxygen than the rest of the body. The brain can live without oxygen for between five and 10 minutes. The adult human brain is about three pounds. It uses about 20% of the oxygen the rest of the body does. It also has more nerves cells than the Encyclopedia Britannica. The brain generates more electricity per day than all other telephones worldwide.
There are over 500 functions in the human body. Some of these functions are digestion, filtering, and breathing. The "chemical factory" of our bodies is the liver.
FAQ
Did you know that there are approximately 1.6 billion metric tons of trash produced every day in the world?
The United Nations states that an average person produces more than 2.5 pounds of waste per day. That's over 25 billion pounds of garbage each year!
Most of this rubbish ends up in landfills or incinerators. But, what happens when those dumpsters fill up? It goes to the United States, where most of it is exported. The rest is dumped abroad, where it pollutes other ecosystems. Now, we know the exact location of all this garbage. Mike Sexton is his nickname. He runs Waste Watchers, a company that monitors the movements of trucks carrying trash all across North America. He then reports back about what happens next.
Sexton said he enjoys his job. CNN spoke with Sexton that they have a lot fun. "We often see large rigs passing through our town and we will follow them. "Sexton started following truck driver almost 20 years back.
He stated, "I just fell in Love with It."
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 along the road and saw this structure. He backed up and entered the building. "There were two enormous roll-off containers filled with stuff. The man took all the stuff out and filled up his truck with more. "The man looked around the area and decided to unload all of it. There were lots of old tires, rags furniture, mattresses, mattresses, cans, cans, and other items. "It was a complete mess. But it had been cleared out before he arrived. There wasn't any trash anywhere."
This is the reason why it happened. It's because this area used to be a recycle center. People would drive from all over the country to recycle their trash. Sexton explained, "They would bring their household goods and take them here," and they would then empty the containers.
This could happen hundreds of time per week. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. The owner finally decides to stop using the truck.
But, this isn't the only problem that our planet is facing.
The majority of these particles are made of small pieces of plastic. Some end up in rivers and oceans, while others end up in fish's stomachs.
Experts warn that the world may soon face a shortage of food if we don't make any changes. Experts warn, "If you keep going like you're going," we could soon face a global food shortage. But most people don't seem to be worried, even though scientists are unanimous in warning us that the world is heading towards disaster.
How does the brain control the functions in your body?
The brain relays messages to other parts of the body to ensure their functionality. Your brain controls all that happens in your body. 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 consists of billions of nerve cells connected in groups called neurons. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Each neuron has its own cell membrane around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. The electric charge that causes the neuron's fire is created by ion movement.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. In turn, the second neuron also fires.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. The impulse travels along an synapse between the neurons. The transmitter binds to the receptors on the postsynaptic neural cell, which triggers the firing of that neuron.
For communication within the nervous systems, neurotransmitters are essential. They are also responsible for coordinating activity between various parts of the brain.
Is there a Hollywood blacklist?
There is a Hollywood blacklist.
But the list isn't made public. We don't know the names. But, here's why it matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. The studios would be out of business as they lose money. Which means they'd cut back on spending money on movies. This would lead to fewer opportunities and less money for blacklisted directors. This could lead to them going bankrupt.
This could lead to more victims.
A contract may be required to agree to not speak against employers if someone attempts to make an Oscar winning movie. Producers and directors who want to be nominated are subject to the same restrictions.
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. Negative comments about your employer will most likely lead to you being unemployed. And that's not good for anyone.
There are many people who have been falsely accused. They've had the toil to clear their name.
This must be stopped before it happens again. It is essential that everyone has the freedom to express their opinions.
Also, we must take down the Hollywood blacklist.
What is the most mysterious location on Earth?
Antarctica is considered the most mysterious area on Earth.
Why do we find this place so intriguing? Because it's unlike any other place in the world.
It is isolated, remote, and very hard to visit. However, there's more to this location than meets the eye.
You'll also find the strangest species of wildlife in this natural wonder.
So let's explore how this remarkable destination became famous for its mystery.
Antarctica, The South Pole
No one knows exactly why Antarctica was named Antarctica. Some believe it means "land of ice." Others believe it derives from Greek mythology.
Antarktis in ancient Greece was the name given the island where Zeus' twin brother brothers were born. According to legend, one of the twins was born in winter. The term antarctic is derived from this.
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.
Whatever the reason Antarctica holds a special fascination, people have always loved it.
It is the continent with the lowest, windiest and highest temperatures. It is too cold to support trees, plants, and animals.
Yet, life is abundant in this frozen wilderness.
It is home to approximately 90 percent of all life on Earth. There are about 50% of the world's animal, plant and plant species.
What is the secret to Antarctica's unique environment? Here, water is frozen into ice rather than vaporizing into the air.
This creates large masses of ice that float above the ground.
These floating glaciers cover over 80%. These glaciers are getting larger each year.
The Antarctic ice sheet has grown 60ft since 1960.
If the melting continues, sea level could rise up to 200ft. It could result in massive flooding all over the world.
But not everyone thinks this is bad news. Some scientists believe that global warming can be beneficial. They say that as temperatures rise, the ice sheets might melt faster, causing floods that flush out tons of toxic chemicals from our soil and bodies.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
