You can learn fascinating facts about your body whether you're a scientist, or just curious. There are thousands upon thousands of biological systems that make up the human body. Each system is designed for a specific task. 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 created during the Big Bang 13 million years ago. The human body has 39 trillion cells in its microbial biome.
Teeth make up the skeletal system of the body. An adult's set of teeth has approximately 32 teeth. Teeth are not considered to be bones but are part of the bone system. The hardest substance found in the human body, enamel is used to make teeth.
Adult human hearts beat approximately 36,500,000x per year. An adult's average blood supply is five liters. The adult bladder can hold 16-24 ounces urine. Most people draw their lungs in the same way. A human adult lung has a surface area approximately 70 square metres.
More than 600 skeletal muscles make up the human body. Each muscle is composed of two parts. There are muscles that pull in opposite directions. The human body is capable of generating 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 produces enough heat to boil half of a gallon in 30 minutes. It produces heat that aids in digestion. This heat helps maintain the body's homeostasis. The heart can exert enough pressure to pump blood up to 30 feet.
There are 100,000 miles of blood vessels in the human body. The circulatory system includes the heart, arteries veins, capillaries, and veins. It transports oxygen, carbon dioxide, as well as nutrients throughout your body. It also removes waste from the body. The kidneys filter out two quarters of the waste from the body.
The human nose can identify 50,000 different smells. It also produces enough electricity for a lightbulb to be lit. The human eye can see ultraviolet light.
The largest organ in our body is the brain. It houses 100 billion nerve cells. 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 in at 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 per day than all of the telephones in the world combined.
The human body has over 500 different functions. Some of these functions include the ability to digest food and filter out waste. The liver is often referred to as the "chemical factory of the body".
FAQ
What are 5 interesting facts about the liver?
The liver is responsible both for breaking down toxins as well as storing vitamins, minerals. 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 could indicate liver problems.

What is the most secretive location in the entire world?
The answer may shock you. It could even make you uncomfortable, because it challenges how reality is perceived and lived. There is a reason this place exists and it's not as you might expect.
It was also called the City of God in ancient Greek. It was called the City of Destruction by the Bible.
It's also known as Kashi (Kashmir) in India. It's also known as Novgorod in Russia.
But here in America, it goes by another name - The Town That Disappeared.
One tiny town in western New York State lost its 1,200 inhabitants without trace. It was abandoned without any remains, including no bodies, cars, or houses. The only thing that survived was a road sign, which pointed to its former location.
The little village vanished, with no trace of its existence. Some believe the earth swallowed them up. Others claim that a meteorite hit destroyed it. Others claim it was taken away by aliens.
Whatever happened, the residents of this once-thriving community are convinced that their town isn't gone forever. They had just moved to a new town.
Even a website exists to help track down the disappearances of the lost city Zugspitz.
The question is, where did this place go? It's in Switzerland, actually!
You can find Zugspitze at the border of Austria and Germany. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated my that so many towns have disappeared but others still exist. Why do some disappear while others survive? I decided to investigate.
I was interested in learning more about these mysterious towns that are disappearing. What is the secret to a town's disappearance? How does one place go extinct?
There are many theories regarding the phenomenon of towns disappearing. One theory is that a city disappears after all buildings have been demolished. Another theory suggests that the town simply moves somewhere else. Another theory suggests that the town has never existed.
Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video examines the history and current status of these places.
Which is the most mysterious spot on Earth?
Antarctica is one of the most mysterious places on Earth.
Why is this place so amazing? It is unlike any other place on Earth.
It is difficult to access because it is remote and extremely isolated. There is much more to this place than meets the eyes.
This natural wonder is also home to some of the strangest wildlife species.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some say it means "land on 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 the name was derived from the Greek words tropos, which means turn, and anti, meaning against. This would mean land turned away from the sun.
Whatever the reason Antarctica has always been a fascination for people.
It is the highest, coldest, windiest, dryest, and most populated continent. It is too cold for trees, plants and animals.
Yet, life is abundant in this frozen wilderness.
It is home to approximately 90 percent of all life on Earth. 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 and becomes ice instead of evaporated into the air.
This creates large masses of ice that float above the ground.
These glaciers are responsible for covering 80% of the continent. They're getting bigger every year.
The Antarctic ice has grown 60 feet so far since 1960.
The sea level will rise up to 200 feet if melting continues. This could lead to massive flooding across the globe.
This is not necessarily bad news. Global warming may be beneficial for some scientists. 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.
What is the most interesting fact about the human body?
Two eyes, two ears and two nostrils are part of our bodies. We also have four limbs: a mouth, nose, penis, and four limbs. That's right, we have more than 50 parts of our bodies, but one thing is missing. A heart.
A heart is the pump that circulates blood throughout a body. The blood travels through the veins and arteries, transporting oxygen and nutrients to cells. It also removes carbon dioxide.
The heart pumps out approximately 5 liters of blood per minute. This is equivalent in daily coffee consumption to an adult who consumes approximately 2 to 3 cups.
Blood flows through the heart 24 hours a day, 365 days a year. While sleeping, your heart beats close to 100 times per minute.
Skin color can be used to determine if someone has a medical condition. Looking closely at the skin's surface, you can see tiny blood vessels called capillaries. These tiny vessels transport blood from the larger blood vessels to the heart. The skin turns blue or violet when blood flow becomes blocked.
People with sickle cells lack red blood cell. Patients with sickle cell disease have their blood become sticky and harden, leading to severe illness.
To stop bleeding from a cut, you can apply a bandage to the wound. For wounds to heal properly, blood must flow. Doctors will insert a needle under the skin to access the vein near the injury. This allows blood drainage from the injury area.
Doctors may also insert catheters (catheters), in an artery to treat a blood clot. This keeps the patient alive till the blood clot dissolves naturally.
Statistics
- "It is estimated that 75% of people have at least mild gum disease, with the most common symptoms being bleeding when brushing, bad breath, and dark and swollen gums," Dr. Ron Baise, a London-based dentist, tells Romper. (romper.com)
- Your mouth makes a lot of saliva every day It might seem like way too much, but your salivary glands typically produce anywhere from 0.5 and 1.5 liters a day, according to a 2009 study published in the Journal of Medicine and Life. (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)
- In one 2014 study published in the Archives of Medical Science that sought to study the prevalence of these mites, research showed that 41% of the people had them hanging out in their eyelashes. (romper.com)
