No matter if you're a scientist (or a curious layperson), you can learn many fascinating facts regarding the human body. There are thousands of biological systems in the human body, and each is designed to perform a specific task. The human body is a marvellous place. There are many things you can learn about the skeletal and circulatory systems, as well as the digestive system.
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. 39 trillion cells are estimated to make up the human microbial Biome.
Teeth are part of the skeletal system. There are about 32 teeth on an adult's 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.
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 of urine. Most people draw the same size lungs. The surface area for adult human lungs measures 70 square metres.
More than 600 skeletal muscles make up the human body. Each muscle has two working parts. There are also muscles which pull in different directions. The human body contains 20 tons force. 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 generates enough heat to boil half a gallon of water in 30 minutes. It also produces heat that is useful for digestion. This heat is used to maintain body homeostasis. The heart can exert enough pressure to pump blood up to 30 feet.
The human body has 100,000 miles of blood vessels. The circulatory systems consists of the heart as well as the arteries, veins, capillaries and blood vessels. It transports oxygen, carbon dioxide, as well as nutrients throughout your body. It also eliminates waste from your body. Two quarts of waste are removed from the body by the kidneys.
Human nose can detect 50,000 different smells. It also produces enough electricity for a lightbulb to be lit. 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 consumes more oxygen than all other parts of the body. The brain can live without oxygen for between five and 10 minutes. The adult human brain weighs in at three pounds. It consumes about 20% more oxygen than the rest of our bodies. It also contains more nerve cells that the Encyclopedia Britannica. The brain generates more electricity per day than all other telephones worldwide.
There are more than 500 functions within the human body. Digestive functions include filtering and removing waste and breathing. The body's "chemical factory", the liver, is often called.
FAQ
How does the brain control the functions of your body?
To ensure that other organs and muscle functions work together, the brain sends messages. Your body's functions are controlled by your brain. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made up billions of nerve cell networks connected in groups known as neurons. Neurons communicate by sending electrical signals, called action potentials, on axons. 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 electric charge that causes the neuron's fire is created by ion movement.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters bind with receptors on the second nerve cell, opening ion channel channels to allow ions in and out. In turn, the second neuron also fires.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds to the receptors on the postsynaptic neural cell, which triggers the firing of that neuron.
Communication within the nervous system is possible thanks to neurotransmitters. They coordinate brain activity among different parts.
Is there a Hollywood blacklist of actors?
There is an Hollywood blacklist.
But, the list has not been made public. The names are not known to us. It matters because of this.
The secret is because the directors and actors on blacklist wouldn't have any job opportunities. Thus, they would leave the industry and studios will lose money. This would mean that they would cut back on movie production. The blacklisted filmmakers would have fewer chances. Which would lead them to go bankrupt.
This could result in even more victims.
When someone tries making an Oscar winning movie they might be asked for a contract. This means that they can't publicly criticize their employer. 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 speak negatively about your employer, you will likely be fired. And that's not good for anyone.
Many people have been wrongly accused. These people have had to fight to clear their names.
We must stop this from happening again. Everybody should be able to freely express themselves.
Also, we must take down the Hollywood blacklist.
Five interesting facts about your liver.
The liver is responsible to detoxify toxins and store vitamins and minerals. It helps maintain a steady body temperature and regulates blood pressure.
Are you familiar with the expressions, "I feel sluggish today", or "my head feels heavy"? These symptoms could indicate liver problems.
Common signs include yellowing skin, dark urine, fatigue, nausea and vomiting, weight loss, stomach cramps (yellow coloration), itching, and jaundice (yellow colouration). These aren't all warning signs. If you are experiencing any of these signs, it is important to consult your doctor right away.
The liver is an essential organ. It is an important organ that plays a vital role in detoxification.
-
An adult liver weighs around 1,400 grams.
-
A baby's liver is about half the size of an adult's at birth. It is four times larger by the time an infant turns three.
-
The liver is located just below the rib cage on the left side of the abdomen.
-
There are 16 major lobes of the liver. But there are also many smaller ones.
-
Red blood cells make up approximately 10 million of the liver's total.
What dark secrets can Hollywood keep from you?
Hollywood is filled with secret societies. Some secret societies are cultlike groups that have strict rules and rituals. Other clubs are for people who share common interests.
But there are also more nefarious organizations that control much of the industry. Companies such as the MPAA, which determines film ratings, or the RIAA (Recording Industry Association of America), that set music licensing fees, are examples of these.
Numerous unions and guilds also represent actors, directors, writers, producers, etc. Most major movie studios and television networks are owned by large corporations which own these various organizations.
It doesn't really matter how secretive an organization may appear, there is always someone who knows exactly what they do. But we don't have to fear them.
Instead, we should embrace them. Because they give us information that allows us to make better decisions.
They tell us what movies will likely succeed, what songs will be popular, and what books will best sell.
They allow us to make informed decisions about what we buy, watch and listen to.
Because we can trust them, we can ignore their advice when it conflicts with our tastes.
And because we've chosen to ignore them, they become even more powerful. They are the ultimate arbiters and judges of taste.
If you don't like their words, you can choose to ignore them.
Let's now look at some lesser-known, but still very real Hollywood secret organizations.
Observe why they are important.

How To
American history is full of secret societies and clubs
American History has many secret societies and clubs that are fascinating. Their mystery is just one reason. A second reason is their impact on society.
Secret societies have been used throughout America's history for promoting ideas that would otherwise not be accepted. Some of these ideas include racism and anti-Semitism. These groups also contributed to the spread of political ideologies, such as communism & socialism.
The Ku Klux Klan is the most prominent American organization. This group was established in 1865, after the Civil War had ended. It was created to protect white men against African Americans.
The Knights Templar and Freemasons were also created during this time. They all had similar goals and beliefs.
Another interesting thing about secret societies is the fact that membership was often restricted to males. However, these groups had some female members. These women were Emma Goldman and Margaret Sanger as well as Susan B Anthony.
Not only the above mentioned groups, but also other secret societies didn't share the same ideals. The Order of Skull & Bones for instance was founded in 1832. Their goal was to create an elite class within the United States.
