FAQ
How does the brain regulate the functions of the body?
The brain relays messages to other parts of the body to ensure their functionality. Your brain controls all that happens in your body. It tells your stomach to digest food and your lungs to breathe air; it tells your arms and legs to move.
Your brain is made up billions of nerve cell networks connected in groups known as neurons. 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. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. Ion movement is what causes the neurons to fire.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters bind to receptors on the second neuron, opening ion channels so ions can pass in and out of the channel. This causes the second neuron to fire too.
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 also help coordinate activity between different parts of the brain.
Here are 5 fascinating facts about the liver
The liver is responsible for breaking down toxins and storing vitamins and minerals. It regulates blood pressure and maintains a stable body temperature.
How often do we hear someone say, 'I feel sluggish today' or 'my head feels heavy'? These symptoms may be a sign of liver disease.
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 the only warning signs. You should immediately consult your doctor if you have any of these symptoms.
The liver is an important organ. It is essential for detoxification and metabolism as well as reproduction.

-
The liver is divided into 16 major lobes. However, there are many smaller lobules that are within these lobes.

Do you wonder how much trash is produced each day across the globe?
According to the United Nations, the average person produces over 2.5 pounds of daily waste.That adds up to over 25 billion pounds of garbage per year!
The majority of this garbage ends up in incinerators or landfills. But what happens when the dumpsters become full? It goes to the United States, where most of it is exported. It then gets dumped in foreign countries, polluting their ecosystems. However, now we know where all that trash goes. Mike Sexton is his real name. He is the founder of Waste Watchers. He watches over trucks that transport trash across North America. He then reports back about what happens next.
Sexton claims he is very satisfied with his job. CNN asked Sexton if he thought it was a lot of fun. "You know, we see these big rigs come through town, and we'll follow them. "Sexton started following truck drivers nearly 20 years ago.
He stated that he fell in love with the product.
His favorite story involved a driver who pulled off at an abandoned gas station near Los Angeles. Sexton said that the man was searching for a place to store his stuff. "He drove down the road and saw this building. He backed up and entered the building. "There was a pair of large, full-sized roll-off boxes. He took out everything and began to fill up the truck. "Then he took out everything and began to fill up the truck. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was just an absolute mess. It had been cleaned up before he arrived. There wasn't any trash."
This begs the question: Why? 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 they would bring household items and take them to the building. Then, after they were done, they would empty the containers.
This could happen hundreds of time per week. It can happen hundreds of time per week. Eventually, the truck is so full of junk it stops running. 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. Others end up in rivers, oceans or the stomachss of fish.
Experts warn that if there is no change, the world could soon be facing a food shortage. Experts warn that "if we keep going the way we are, we're not going make it," although scientists agree that the world is heading toward disaster. Most people, however, don't seem to be concerned.
What is the most surprising fact about your body?
We have two eyes and two ears, two nostrils each, four limbs, four limbs and a penis. Yes, more than 50 parts to our bodies. But one thing is missing. The 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 of an adult drinking 2 to 3 cups of coffee each day.
The blood flows throughout the heart 24/7, 365 days a calendar. 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. You can see tiny blood vessels, called capillaries, when you look closely at the skin. These tiny vessels transport blood from the larger blood vessels to the heart. The skin turns blue or violet when blood flow becomes blocked.
Red blood cells are missing in people with sickle-cell disease. Their blood becomes very sticky and hardened, leading to serious illness.
To stop bleeding from a cut, you can apply a bandage to the wound. The wound must remain open for blood to flow 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 can also insert catheters into the artery close to the area where the bloodclot has formed. This helps to keep the patient alive until the blood clot disintegrates naturally.

Hollywood scandals that shocked the world
There's nothing more shocking than watching someone become famous for the wrong reasons. However, there is nothing worse than watching them fall from grace.
It's amazing to see how the industry responds to their mistakes. We have all heard of celebrities who overdosed on drugs and alcohol. Some even died young because of it.
The worst part about this is that these same stars come out with their problems and are ridiculed by everyone. We were there last week.
Heath Ledger gave up after a long career that was successful. After a short battle with death, Heath Ledger succumbed to prescription pills.
His family and his friends struggled with the news and the media went after him.
Heath was once considered to be one of today's most talented actors. 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 began using drugs and drinking heavily. He was eventually able to get clean and went to rehab.
Now that he was sober, he wanted to make amends. He produced a documentary called Room 237 that documented the making process of The Shining. 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 was unsuccessful in his attempts to get back into Hollywood. 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. However, it would be nice if he could get some help before things spiral out of control.
We hope Heath’s tale will be a wakeup call to anyone who may believe that they can still have all.
