There are many fascinating facts about human bodies, regardless of whether you're an expert or a layperson. There are thousands and thousands of biological system in the human body. Each is designed to do a specific job. The human body is an amazing 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 were formed at the Big Bang 13 billion year ago. The human body has 39 trillion cells in its microbial biome.
The skeletal system of the human body includes teeth. Adult teeth have 32 teeth. Teeth are not considered as bones, but they make up part of the skeletal systems. Teeth are made of enamel, which is the hardest substance in the human body.
An adult's heart beats approximately 36,500,000 times per 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 in the same way. A human adult lung has a surface area approximately 70 square metres.
There are more than 600 skeletal bones in the human body. Each muscle has two working parts. There are also muscles which pull in different directions. The human body has 20 tons of force. The heart is the only muscle that doesn't tire. 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 can boil half a gallon water in 30 minutes. 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.
Human bodies have over 100,000 miles in blood vessels. The circulatory network is composed of the heart and arteries, veins and capillaries. It transports oxygen, carbon dioxide, as well as nutrients throughout your body. It also removes waste from our bodies. The kidneys filter out two quarters of the waste from the body.
The human nose is capable of recognizing 50,000 different scents. It also produces enough electricity to light one lightbulb. The human eye is capable of detecting ultraviolet light.
The brain is the largest organ of the body. It contains 100 billion nerve cells. The adult brain requires more oxygen than any other part 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 contains more nerve cells than 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 include digesting food, filtering 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 relays messages to other parts of the body to ensure their functionality. Everything that happens within your body is controlled by the brain. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Action potentials are electrical signals that neurons send to one another. Each neuron has a cell membrane surrounding its nucleus. The cell membrane houses channels that allow ions, such as potassium and sodium, to enter and exit the cells. The neuron is lit by an electric charge created by the movement of ions.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters can bind to receptors at the second neuron. They open ions channels, allowing ions to move in and outside of the channel. In turn, the second neuron also fires.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. An impulse travels along a synapse that connects the two neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
Neurotransmitters are important for communication within the nervous system. They also help coordinate activity between different parts of the brain.
Have you ever wondered what amount of trash is generated each day worldwide?
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? Most of that trash is shipped out of the country. It then gets dumped in foreign countries, polluting their ecosystems. However, now we know where all that trash goes. Mike Sexton is his real name. He is the founder of Waste Watchers. He watches over trucks that transport trash across North America. He reports back to us about the next steps.
Sexton stated that he finds the job very satisfying. CNN asked Sexton if he thought it was a lot of fun. "We'll be following these big rigs through town. "Sexton began to follow truck drivers around 20 years ago.
"It's all I felt," he stated.
His favorite story involved a driver who pulled off at an abandoned gas station near Los Angeles. Sexton described, "The guy was looking somewhere to put his load." "He saw the building as he drove down the road. He pulled over and went in. "There were two huge roll-off containers there filled with stuff. He took out everything and began to fill up the truck. "The man looked around the area and decided to unload all of it. There were old tires and rags, furniture pieces, mattresses, mattresses and boxes. It was a complete mess. But it was cleaned out before he came. 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 that people would bring home their household items, and then take them to the building. After they were done, they would dispose of the empty containers.
You might see this happen hundreds of times a day. This could happen hundreds times per week. Finally, the truck stops running completely due to its excessive junk. And eventually, the owner decides to abandon the vehicle.
Trash isn’t the only problem we face on the planet.
The majority of these particles are made of small pieces of plastic. Some of these plastics end up in rivers or oceans.
Experts warn that the world may soon face a shortage of food if we don't make any changes. Experts warn that "if we keep going the way we are, we're not going make it," although scientists agree that the world is heading toward disaster. Most people, however, don't seem to be concerned.
What are 5 interesting facts about the liver?
The liver is responsible of breaking down toxins and storing nutrients. It also regulates blood pressure, and maintains our body's temperature.
Is it not often that we hear people say "I feel sluggish today" and "my head feels heavier?" These symptoms may be a sign of liver disease.
You may notice symptoms such as dark urine, yellowing skin and fatigue. These aren’t the only warning signs. These are not the only warning signs. Make an appointment immediately with your doctor if they occur.
The liver, an essential organ, is vital. It is responsible for detoxification as well digestion, metabolism and immunity.

What is the most mysterious place on earth?
Antarctica is considered the most mysterious area on Earth.
We find this place so fascinating. Because it's unlike any other place in the world.
It is very remote and isolated. However, there's more to this location than meets the eye.
You'll also find the strangest species of wildlife in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
Antarctica is not known by anyone. Others believe it means "land with ice". Others believe it comes from Greek mythology.
Antarktis in ancient Greece was the name given the island where Zeus' twin brother brothers were born. One of the twins was said to have been born in winter. Therefore, the name antarctic.
Others believe the name was derived from the Greek words tropos, which means turn, and anti, meaning against. This would translate to land that is turned away from the sun.
Whatever the reason Antarctica has held a special fascination for people, it is undeniable.
It is also the lowest, windiest continent, driest, and highest. Because it is so cold, there aren't any trees, plants or animals.
Yet, life is abundant in this frozen wilderness.
Here are about 90% of all the living creatures on Earth. You can find approximately half the world's species of animal and plant plants here.
What is it that makes Antarctica so unique? Here, water freezes into ice instead of evaporating into the air.
This causes large masses to form of ice which float high above the ground.
These floating glaciers cover over 80%. They are growing in size every year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
If the melting continues, sea level could rise up to 200ft. This could lead to massive flooding across the globe.
Not everyone believes this is bad news. Some scientists think global warming might 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.
Others, however, warn that this theory sounds almost like a plot for a science fiction film.
Statistics
- The average human adult male heart rate is between 70 and 72 beats per minute, while the average for adult women is between 78 and 82 beats, which is significantly faster, according to 2014 published in the Journal of Clinical and Diagnostic Research. (romper.com)
- It might not sound like something that's truly plausible — and it is quite rare — but according to a 2015 study published in the Asian Cardiovascular & Thoracic Annals, it's possible to hurt yourself and even break a rib just by sneezing. (romper.com)
- In fact, nearly 24% of U.S. women are affected with one or more pelvic floor disorders, according to research funded by the National Institutes of Health. (romper.com)
- A 2012 paper published in the Proceedings of the National Academy of Sciences reported that people blink about 15 to 20 times each minute, meaning, if you do the math, you spend about 10% of the time that you're awake blinking. (romper.com)

American history's secret societies and clubs
The secret societies and clubs in American History are fascinating for many reasons. Another reason is the mystery that surrounds them. Their impact on our society is another reason.
Secret societies and clubs have been used throughout America’s history in order to promote ideas that might otherwise be considered taboo. Some of these ideas include racism and anti-Semitism. These groups also helped spread political ideologies such as communism and socialism.
The Ku Klux Klan, the most famous American organization, is also the most important. This group was formed in 1865 after the Civil War ended. Its purpose was to protect white men from African Americans.
Other organizations established during this period were the Knights Templars and Freemasons. These groups all shared similar goals and beliefs.
Another interesting aspect about secret societies is their ability to restrict memberships to men only. These secret societies also included women. These women included Emma Goldman. Margaret Sanger and Susan B Anthony.
Other secret societies, aside from the ones mentioned, did not share the same ideals. The Order of Skull & Bones for instance was founded in 1832. Their goal was to create an elite group within the United States.
