FAQ
How does the brain control the functions in 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 you your stomach to digest food; your lungs to inhale air; and it tells you your arms and legs how to move.
Your brain is composed of billions and billions 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. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. Ion movement is what causes the neurons to fire.
Neurotransmitters are chemicals released when a neuron fires. Neurotransmitters attach to the receptors of the second neuron and open ions channels for ions to pass in and out. The second neuron also fires.
When another neuron sends an impulse to the presynaptic neural cell, neurotransmitter is released. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds to receptors on the postsynaptic neuron, triggering the firing of the postsynaptic neuron.
Neurotransmitters are important for communication within the nervous system. They coordinate brain activity among different parts.
Ever wonder how much trash gets produced each day around the world?
According to the United Nations the average person creates more than 2.5 lbs of waste daily. That adds up over 25 billion kilos of garbage every year.
Most of this rubbish ends up in landfills or incinerators. But, what happens when those dumpsters fill up? Most of that trash is shipped out of the country. The rest is dumped abroad, where it pollutes other ecosystems. Now, we know the exact location of all this garbage. Mike Sexton is his real name. He runs a company called Waste Watchers.He spends his days watching the movements of trucks transporting trash across North America. He reports back to us about the next steps.
Sexton stated that he finds the job very satisfying. CNN's Sexton said, "We have a lot to enjoy." "You know, we see these big rigs come through town, and we'll follow them. "Sexton started following truck driver almost 20 years back.
He stated that he fell in love with the product.
He loved the story of the driver who pulled into an abandoned gas station near Los Angeles. Sexton recalls, "The guy was searching for somewhere to put his loads." "He drove down the road and saw this building. So he pulled over and went inside. "There was a pair of large, full-sized roll-off boxes. He took out everything and began to fill up the truck. "The man looked around the area and decided to unload all of it. There were old tires and rags, furniture pieces, mattresses, mattresses and boxes. "It was just a total mess. But it had been cleared out before he arrived. There wasn’t trash everywhere."
Why did this happen? Well, the answer is that this particular location used to be part of a recycling center.People who learned about this facility would drive here to recycle their trash. Sexton explained, "They would bring their household goods and take them here," and they would then empty the containers.
This could happen hundreds of time per week. The truck can be stopped running if it is so full of junk that it has to come back hundreds of times per week. The truck eventually stops running and the owner decides that it is time to get rid of the vehicle.
Trash, however, isn't the only problem facing our planet.As you may have noticed, things are getting worse.According to experts, pollution levels have risen dramatically in recent years.More than half of all water bodies on Earth are polluted.Pollution from industrial chemicals has increased by more than 30 percent since 1980.Even the air we breathe is becoming increasingly toxic.A study by the World Health Organization found that the average person inhales around 100 million particles daily.
The majority of these particles are made of small pieces of plastic. Others get washed into rivers or oceans.And when they reach the ocean, they often end up in the stomachs of fish.
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 is the most fascinating fact about the human body
We have two eyes, two ears, two nostrils, four limbs, a mouth, a nose, and a penis. You're correct, there are more than 50 parts in our bodies. But, one thing is missing. A heart.
A heart is a pump, which circulates blood throughout our bodies. The blood moves through the arteries and veins to transport oxygen and nutrients into the cells, and remove carbon dioxide.
The heart pumps out approximately 5 liters of blood per minute. This is equivalent of an adult drinking 2 to 3 cups of coffee each day.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. While sleeping, your heart beats close to 100 times per minute.
You can tell whether someone is healthy or unhealthy because of the color of their skin. Capillaries are tiny blood vessels visible on the skin's surface. These small vessels carry blood from the large blood vessel in the skin back towards the heart. When blood flow is blocked, the skin turns blue or purple.
Red blood cells are not available to sickle cell patients. Their blood becomes very sticky and hardened, leading to serious illness.
Bandages are used to stop bleeding after you have cut yourself. Blood must continue to flow to allow the wounds to heal properly. Doctors insert a needle into the injured area through the skin. This allows blood drainage from the injury 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.
What is the most mysterious place on earth?
Antarctica is considered the most mysterious area on Earth.
Why is this place so amazing? Because it is unlike anything else on Earth.
It is isolated, remote, and very hard to visit. But there is more to this site than meets the eye.
You will also find some of the oddest wildlife species in this natural wonder.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
Antarctica is not known by anyone. Some believe it refers to "land of ice". Others believe it comes out of Greek mythology.
Antarktis is the name Antarktis was given to an island in ancient Greece by Zeus' twin brothers. According to legend, one twin was born in winter. Hence, the word antarctic.
Others believe the name was derived from the Greek words tropos, which means turn, and anti, meaning against. This would be land turned away form the sun.
Whatever the reason, Antarctica has always held a special 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.
About 90 percent of all living things on Earth live here. It is home to approximately half of all world's animal and plant species.
What makes Antarctica so special? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large ice masses to rise above the ground.
These floating glaciers cover 80% of the continent. They're getting bigger every year.
The Antarctic Ice Sheet has grown 60 feet in the past 60 years.
If the melting goes on, the sea level may rise by as much as 200 feet. This could lead to widespread flooding.
This is not necessarily bad news. Some scientists believe that global warming can be beneficial. According to scientists, global warming could be good for us because the melting of the ice sheets will accelerate, which can lead to floods that release toxic chemicals into our soil and bodies.
But others warn that this theory sounds like a plot from a science fiction movie.
