You can discover many interesting facts about the human body, whether you are a scientist or just a curious layperson. There are thousands and thousands of biological system in the human body. Each is designed to do a specific job. The human body can be described as a vast and complex wonderland. Learn about the skeletal system and the circulatory system.
The human body is made up of about 7,000,000,000,000,000,000,000,000,000 (7-octillion) atoms. These atoms formed 13 billion years ago during the Big Bang. It is estimated that the microbial biome of the human body is 39 trillion cells.
The skeletal system of the human body includes teeth. Adult teeth have 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.
An adult's heart beats approximately 36,500,000 times per year. An adult's average blood supply is five liters. The adult bladder can hold 16-24 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 that pull differently. 20 tons of force is contained in the human body. The heart is the only muscle of the body that doesn't fatigue. The human eye has 2 million working parts, and can differentiate 10 million colors.
25 million cells are created every second by the human body. It produces enough heat to boil half of a gallon in 30 minutes. It also produces heat for the digestion of food. This heat helps maintain the body's homeostasis. The heart can pump enough blood to reach 30 feet.
There are 100,000 miles of blood vessels in the human body. The circulatory network is composed of the heart and arteries, veins and capillaries. It is responsible for moving oxygen, carbon dioxide, nutrients, and other substances 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 can distinguish between 50,000 smells. It also generates enough electricity to light a lightbulb. The human eye can sense ultraviolet light.
The human brain is the biggest organ in the body. It contains 100 million nerve cells. The adult brain consumes more oxygen than all other parts of the body. The brain can survive without oxygen for five to 10 min. The adult human brain weighs in at three pounds. It uses about 20% of the oxygen the rest of the body does. It also has more nerve cell than the Encyclopedia Britannica. The brain generates more electrical impulses per day than all of the telephones in the world combined.
There are over 500 functions in the human body. Digestive functions include filtering and removing waste and breathing. The liver is sometimes called the "chemical plant" of the body.
FAQ
Have you ever wondered how much trash is produced worldwide each day?
According to the United Nations there are more than 25 billion tons of garbage produced each year.
Most of this trash ends up in landfill dumps or incinerators.But what happens when those dumpsters get full? All that trash ends up being shipped out of country. It is then dumped in other countries, where it pollutes their ecosystems.But now, thanks to the work of one man, we know exactly where all this trash goes. Mike Sexton is his real name. He owns a company called Waste Watchers. He spends his time watching trucks hauling trash around North America. He reports back to us about the next steps.
Sexton claims he is very satisfied with his job. CNN interviewed Sexton and said that he has a lot of 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."
His favorite story is about a driver that pulled into an abandoned gas station just outside Los Angeles. Sexton recalls, "The guy was searching for somewhere to put his loads." "He drove down the street and saw this building. He pulled over and went in. "There was a pair of large, full-sized roll-off boxes. The man removed everything from the truck and started to load it again. He then looked around and decided to load everything. There were tires, rags. furniture, mattresses. boxes, bottles, cans. "It was just an absolute 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 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.
This could happen hundreds of time per week. This could happen hundreds times per week. Finally, the truck stops running completely due to its excessive junk. The owner eventually decides to dump the truck.
However, trash is not the only problem on our planet.
Plastic pieces make up most of these particles. Some end up in rivers and oceans, while others end up in fish's stomachs.
Experts say if nothing changes, we could soon face a global food shortage. One expert said, "If we keep going as we are going, we're never going to make it," but most people don’t seem concerned.
What are 5 interesting facts about the liver?
The liver is responsible in breaking down toxins, storing vitamins and mineral, and for regulating blood pressure. It also regulates blood pressure, and maintains our body's temperature.
How often do we hear someone say, 'I feel sluggish today' or 'my head feels heavy'? These symptoms could be signs of liver problems.
Other symptoms include itching, yellowing of the skin, heavy urine, yellowing of the skin, fatigue and nausea. These are not the only warning signs. If you feel any of these warning signs, consult your doctor immediately.
The liver is an essential organ. It is an important organ that plays a vital role in detoxification.
-
The average adult human liver is approximately 1,400g.
-
A baby's liver is about half the size of an adult's at birth. It becomes about four times more large by the age of three than an infant's liver.
-
The liver is located on the left side, just below your rib cage.
-
There are 16 main lobes in the liver, but many smaller lobules are inside the lobes.
-
The liver contains about 10 million individual red blood cells.
Is there a Hollywood blacklist?
There is a Hollywood blacklist.
But, the list has not been made public. As far as we are aware, the names are not even known. It matters because of this.
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. The blacklisted filmmakers would have fewer chances. They would then go bankrupt.
This could eventually 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. This applies to any producer or director who wishes to be nominated.
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 Hollywood has a blacklist. Negative comments about your employer will most likely lead to you being unemployed. That's bad for everyone.
Many people have been wrongly accused. They've had the toil to clear their name.
This is unacceptable behavior and must be stopped. Everybody should be able to freely express themselves.
So we need to take down the Hollywood blacklist.
How does your brain control your body's functions?
The brain sends messages to other organs and muscles to ensure they work together. Everything in your body is controlled and managed by your brain. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Neurons communicate by sending electrical signals, called action potentials, on axons. Each neuron has its own cell membrane around its nucleus. There are channels within the membrane that allow ions such a sodium or potassium to enter and exit the cell. The neuron fires when there is ion movement.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters attach to the receptors of the second neuron and open ions channels for ions to pass in and out. As a result, the second neuron fires too.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. An impulse travels along a synaptic link between the two neuron. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
Communication within the nervous system is possible thanks to neurotransmitters. They also help coordinate activity between different parts of the brain.
