FAQ
How does your brain control the functions within your body?
To ensure that they work together, messages are sent by the brain to other organs. Your body's functions are controlled by your brain. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Every neuron has a cell wall around its nucleus. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. The neuron fires when there is ion movement.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. As a result, the second neuron fires too.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. An impulse travels along a synaptic link between the two neuron. 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 are also responsible for coordinating activity between various parts of the brain.
What is the most surprising fact about your body?
There are two eyes, two ears. Two nostrils. Four limbs. A mouth, nose and penis. Yes, more than 50 parts to our bodies. But one thing is missing. A heart.
A heart is a pump that circulates blood throughout the body. Blood travels through the arteries and veins, carrying oxygen and nutrients to the cells and removing carbon dioxide and waste products.
Each minute, the heart pumps 5 liters of blood. This amount is equivalent to an adult drinking 2-3 cups of coffee daily.
The blood flows throughout the heart 24/7, 365 days a calendar. Your heart beats nearly 100 times a minute while sleeping.
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 vessels carry blood back to the heart from the large blood vessels beneath the skin. The skin becomes blue-colored or purple when blood flow is restricted.
Red blood cells are missing in people with sickle-cell disease. Their blood becomes sticky and hardens, causing them to become very ill.
Bandages are used to stop bleeding after you have cut yourself. Blood must continue to flow to allow the wounds to heal properly. Doctors place a needle in the wound and insert it through the skin. This allows the blood to drain from the injured area.
Doctors also insert tubes (catheters) into the artery near the site where the blood clot forms. This keeps patients alive until the clot has broken up naturally.
Which is the most mysterious spot on Earth?
Antarctica is home to the most mysterious and remote place on Earth.
What is it that makes this place so interesting? Because it is unlike any other spot 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 see how this incredible destination became famous for its mystery.
Antarctica, The South Pole
No one knows exactly why Antarctica was named Antarctica. Some believe it means "land of 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. This is why the word "antarctic" was chosen.
Others believe that the name comes from the Greek words anti meaning against and tropos meaning to turn. This would be land turned away form the sun.
Whatever the reason Antarctica has always been a fascination for people.
It is the highest, coldest, windiest, dryest, and most populated continent. Because it is so cold, there aren't any trees, plants or animals.
Yet, this frozen wasteland is alive.
About 90 percent of all living things on Earth live here. About 50% of the world's plant and animal species can be found here.
What is Antarctica? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large amounts of ice to float above ground.
These floating glaciers cover over 80%. And they're growing larger 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 worldwide flooding.
This does not mean that everyone is wrong. Global warming may be beneficial for some scientists. They suggest that rising temperatures could cause ice sheet melt faster, leading to floods that flush out toxic chemicals from soil and bodies.
Others warn that this theory sounds like something out of a science-fiction movie.
These are five interesting facts about livers
The liver is responsible to detoxify toxins and store vitamins and minerals. It helps maintain a steady body temperature and regulates blood pressure.
We hear it all the time: "I feel sluggish today" or "my head feels heavy". These symptoms could indicate problems with your liver.
Other symptoms include itching, yellowing of the skin, heavy urine, yellowing of the skin, fatigue and nausea. These are not all the warning signs. You should immediately consult your doctor if you have any of these symptoms.
The liver, an essential organ, is vital. It is an important organ that plays a vital role in detoxification.

The average adult human liver is approximately 1,400g.
-
At birth, a baby's liver is half the size of an adult. By age three, it is about four times larger than that of an infant.
-
The liver is located just below the rib cage on the left side of the abdomen.
-
There are 16 major liver lobes. However there are many smaller, more intimate lobules.
-
Red blood cells make up approximately 10 million of the liver's total.
Statistics
- 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)
- "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)
- You spend about 10% of your time awake blinking (romper.com)
- According to a 2018 study published in Free Radical Biology & Medicine, this is because blood pressure is regulated by our innate circadian rhythm and internal clock. (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)

Hollywood scandals that stunned the world
There is nothing more shocking than witnessing someone get famous for the wrong reasons. There's nothing more shocking than watching someone fall from grace.
The best thing about watching how an industry reacts when it makes mistakes is the best part. Many celebrities have used alcohol and drugs in excess. Some even died young because of it.
The worst thing is when these stars are made public about their problems and shunned. That's where we found ourselves last week.
Heath Ledger, after a long and successful professional career, finally gave in to his demons. He succumbed after taking too many prescription medications. After a brief struggle with death, he died.
His family and friends struggled to accept his passing, and the media had a field day bashing him publicly.
Heath was once regarded as one of the best actors today. Two Academy Awards nominations were given to Heath for his role in Brokeback Mountain.
In addition to acting, Heath also wrote and directed films, including A Knight's Tale, Monster's Ball, and Iron Man 3.
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, it was time 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.
Every time Heath tried to get back into Hollywood, something happened. In fact, he was actually twice arrested for drug-related charges.
We don't believe Heath should have been allowed to go back into the entertainment industry. But it would have been nice to get some help before things spiralled out of control.
We hope Heath’s tale will be a wakeup call to anyone who may believe that they can still have all.
