What is the most fascinating fact about the human body
There are two eyes, two ears. Two nostrils. Four limbs. A mouth, nose and penis. It's true, we have more 50 parts of our body, but there is one thing missing. A heart.
A heart is a pump that circulates blood throughout the body. The blood travels through the veins and arteries, transporting oxygen and nutrients to cells. It also removes carbon dioxide.
The heart pumps out about 5 liters per minute. This is equivalent to an adult consuming 2-3 cups of coffee per day.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. When you're asleep, your heart beats approximately 100 times per hour.
You can tell whether someone is healthy or unhealthy because of the color of their skin. 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. If blood flow is blocked, skin can turn blue or purple.
Red blood cells are not available to sickle cell patients. Their blood becomes sticky and hardens, causing them to become very ill.
To stop bleeding from a cut, you can apply a bandage to the wound. The wound must remain open for blood to flow properly. To do this, doctors insert a needle through the skin into the vein next to the injury. This allows the blood from the injured area to drain.
Doctors can also insert catheters into the artery close to the area where the bloodclot has formed. This keeps the patient occupied until the clot is broken down naturally.
Is there a more mysterious place than the Earth itself?
Antarctica is considered the most mysterious area on Earth.
Why do we find this place so intriguing? Because it is unlike any place on Earth.
It is remote, isolated, and extremely difficult to visit. This site has more to it than meets your eye.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's look at how this extraordinary destination became so mysterious.
Antarctica: The South Pole
No one knows exactly why Antarctica was named Antarctica. Others believe it means "land with ice". Some believe it means "land of ice". Others believe it is Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to legend, one twin was born in winter. The term antarctic is derived from this.
Others think the name came from the Greek words anti, meaning against, and tropos meaning turn. This would mean land turned away from the sun.
Whatever the reason Antarctica has always been a fascination for people.
It is the continent with the lowest, windiest and highest temperatures. Because it is so cold, there aren't any trees, plants or animals.
This frozen wasteland is still alive.
Here are about 90% of all the living creatures on Earth. Here are approximately 50% of all the animal and plant species in the world.
What is the secret to Antarctica's unique environment? Here, water freezes in ice rather that vaporizing into the atmosphere.
This results in large masses of ice floating above the ground.
These floating glaciers make up 80%. They continue to grow in size each year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
If the melting continues, the sea level will rise by up to 200 feet. That could cause massive flooding around the globe.
But not everyone thinks this is bad news. Some scientists believe that global warming can be beneficial. They claim that the melting of ice sheets could accelerate as temperatures rise. This would lead to flooding that removes tons of toxic chemicals and soil from our bodies.
Others cautioned that this theory sounds too science fiction.
What is the reason actors are blacklisted?
An actor is more likely to get rejected than a writer. As an actor, it's likely that you will be rejected a lot. You will find someone who loves and accepts you eventually.
Actors are usually very talented, meaning they can make a living almost anywhere. However, most actors aren't interested in making money. Actors love acting and storytelling. So if you're an actor, chances are you're going to put yourself out there.
Sometimes you may be told by the audition panel that you are too young, too old, or wrong for the role. Or, you could lose out on a role in a movie. That happens a lot.
You may be criticised once your casting is complete. Some people will say that you look awful or shouldn't wear makeup. If you're lucky, you won't even hear negative comments.
Sometimes it's because you play a character that's not realistic or authentic. You might play a gay man and everyone assumes that you are straight. You might play a tough woman, but she is very emotional.
You might be asked to change the sound of your voice. Sometimes they ask you to sound like either a boy or a girl. Most times, though, they want you to sound better.
The best way to deal with these criticisms is to ignore them. Actors often feel like they've failed if they're told they did something wrong. The truth is they haven’t done anything wrong.
They were not born with the talent that would make them famous. Sometimes, no matter what they do, they just don't fit the bill.
An actor can be blacklisted for many reasons. Some people don't like actors. Others feel that actors are lazy. Others believe actors cheat.
It doesn't matter what reason it may be, you won’t be banned if you keep trying. There are many opportunities for you to find your role.
As long as you keep trying, you'll eventually succeed.
How does your brain control your body's functions?
To ensure that they work together, messages are sent by the brain to other organs. 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. Every neuron has a cell wall around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. Ion movement creates the electric charge that causes the neuron to fire.
Neurotransmitters, which are chemicals that release neurotransmitters when a neuron fires up, can be found in the space between the neurons and the next one. Neurotransmitters can bind to receptors at the second neuron. They open ions channels, allowing ions to move in and outside of the channel. The second neuron also fires.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. The impulse travels along an synapse between the neurons. The transmitter binds at the receptors of the post-synaptic Neuron and triggers its firing.
Neurotransmitters are important for communication within the nervous system. They coordinate brain activity among different parts.

Hollywood scandals that shocked all of the world
There is nothing more shocking than witnessing someone get famous for the wrong reasons. But there's also nothing worse than seeing them fall from grace.
It is amazing to see how an industry handles its mistakes. We've all heard stories of celebrities who used drugs and alcohol excessively. Some even died young because of it.
It's worse when stars make public their problems, and then are ignored by everyone. We found ourselves in that situation last week.
After a long and successful career, Heath Ledger finally succumbed to his demons. He took too many prescription pills and died shortly after.
His family and close friends had difficulty accepting his death. The media took to him publically.
Heath was once regarded as one of the best actors today. He was nominated for two Academy Awards for his performance in Brokeback Mountain.
Heath was not only an actor, but also directed and wrote films like A Knight's Tale and Monster's Ball.
Hollywood loved Heath, however he soon grew too big for his good looks. He became addicted to drugs and drank heavily. He was eventually able to get clean and went to rehab.
Now that he was sober, he wanted to make amends. He then made "Room 237," a documentary that chronicled The Shining's making. The film was originally supposed to be released in this year's theaters, but it will not make its way into the cinemas until next year.
Heath tried unsuccessfully to get into Hollywood again, but nothing happened. He was actually arrested twice for drug charges.
We are not suggesting that Heath should be allowed back into the show business. However, it would have been nice if he could have gotten some help before things spiraled out of control.
We hope Heath's story will serve as a warning to others who may think they can still have everything.
