Whether you're a scientist or a curious layperson, you can learn many fascinating facts about the human body. There are many biological systems within the human body. Each one is specifically designed to accomplish a particular task. The human body is a wonderland. 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 formed 13 billion years ago during the Big Bang. 39 trillion cells make up the human microbial biome.
The skeletal system of the human body includes teeth. 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.
The average adult heart beats 36,500,000 times each year. An adult's average blood supply is five liters. A person's bladder can store 16-24 ounces worth of urine. Most people draw their lung as one size. The surface area in adult human lung is approximately 70 square meters.
More than 600 skeletal muscles make up the human body. Each muscle works in pairs. There are also muscles which pull in different directions. 20 tons of force is contained in the human body. The heart is our only non-fatal muscle. The human eye is composed of two million parts that can distinguish between 10 million colors.
25 million cells are produced every second in the human body. It produces enough heat to boil half of a gallon in 30 minutes. It also generates heat to aid in the digestion of food. This heat is used by the body to maintain homeostasis. The heart can exert enough pressure to pump blood up to 30 feet.
Humans have 100,000 miles worth of blood vessels. The circulatory systems consists of the heart as well as the arteries, veins, capillaries and blood vessels. It moves oxygen, carbon dioxide, and nutrients throughout the body. It also eliminates waste from your body. Two quarts are filtered by the kidneys.
The human nose can distinguish between 50,000 smells. It also produces enough electricity for a lightbulb to be lit. The human eye can detect ultraviolet light.
The largest organ in our body is the brain. It is home to 100 billion nerve cells. The adult brain requires more oxygen than any other part of the body. The brain can survive five to 10 minutes without oxygen. The adult human brain weighs three pounds. It consumes about 20% more oxygen than the rest of our bodies. It also has more nerves cells than the Encyclopedia Britannica. The brain generates far more electrical impulses daily than all the phones in the world.
Over 500 functions can be found in the human body. Some of these functions include digesting food, filtering waste, and breathing. The liver is often called the "chemical factory" of the body.
FAQ

Is there a Hollywood blacklist.
There is a Hollywood blacklist.
However, the list isn’t public. As far as we know, the names aren't even known. This is why it matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. Thus, they would leave the industry and studios will lose money. This would mean that they would cut back on movie production. This would lead to fewer opportunities and less money for blacklisted directors. Which would lead them to go bankrupt.
This could eventually lead to more victims.
If someone attempts to make an Oscar-winning movie, they may be asked to sign a contract stating that they will not speak out against their employers. The same goes for any director or producer who wants to get nominated for an award.
You hear stories of directors being pressured to remove scenes from films. Directors may threaten to quit projects that don’t align with their vision.
This is why Hollywood keeps a blacklist. Negative comments about your employer will most likely lead to you being unemployed. And that's not good for anyone.
Many people have been wrongly accused. They have had to fight for their freedom.
We must stop this from happening again. It is essential that everyone has the freedom to express their opinions.
We must get rid of the Hollywood blacklist.
How does your brain control the functions within your body?
The brain sends messages to other organs and muscles to ensure they work together. Your body's functions are controlled by your brain. 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 of billions, or neurons, of nerve cells. Neurons communicate with each other by sending electrical signals called action potentials on axons. Each neuron has its own cell membrane around its nucleus. Inside the membrane are channels that allow ions such as sodium and potassium to enter and leave the cell. The neuron is lit by an electric charge created by the movement of ions.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters bind with receptors on the second nerve cell, opening ion channel channels to allow ions in and out. As a result, the second neuron fires too.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. The impulse travels along the synaptic pathway that connects both 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 also help coordinate activity between different parts of the brain.
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 the trash ends up at incinerators and landfills. But, what happens to those dumpsters? All that trash ends up being shipped out of country. It is then shipped out and dumped in other countries. This pollutes the ecosystems. But now we know, thanks to one man. His name is Mike Sexton. He runs a company called Waste Watchers.He spends his days watching the movements of trucks transporting trash across North America. Then he reports back to us about what happens next.
Sexton stated that he finds the job very satisfying. 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 began to follow truck drivers around 20 years ago.
"I just fell in love with it," he said.
Sexton's favorite story was about a driver who stopped at an abandoned gas station in Los Angeles. Sexton said that the man was searching for a place to store his stuff. "He saw the building as he drove down the road. He stopped and pulled up, then he went inside. "There was a pair of large, full-sized roll-off boxes. The man removed everything from the truck and started to load it again. "Then he took out everything and began to fill up the truck. There were lots of old tires, rags furniture, mattresses, mattresses, cans, cans, and other items. "It was a complete mess. It had been cleaned up before he arrived. There was no trash."
So why did this happen? This particular spot used to be a recycling center. People would drive there 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 can happen hundreds of times a week. This could happen hundreds times per week. Finally, the truck stops running completely due to its excessive junk. The owner eventually abandons the vehicle.
Trash isn’t the only problem we face on the planet.
The majority of these particles are made of small pieces of plastic. Some are washed into rivers and oceans. Others end up with fish in their stomachs.
Experts say if nothing changes, we could soon face a global food shortage. "If we keep going like we're going, we're not going to make it," one expert warned.But even though scientists agree that the world is headed toward disaster, most people don't seem worried.
