Whether you're a scientist or a curious layperson, you can learn many fascinating facts about the human body. There are thousands upon thousands of biological systems that make up the human body. Each system is designed for a specific task. It is a wonderful place. The skeletal system, circulatory system, digestive system are just a few of the many topics you can study.
The human body is made up of about 7,000,000,000,000,000,000,000,000,000 (7-octillion) atoms. These atoms were formed at the Big Bang 13 billion year ago. The human body has 39 trillion cells in its microbial biome.
Teeth are part of the skeletal system. An adult's set of teeth has approximately 32 teeth. Teeth are not considered to be bones but are part of the bone system. Teeth are made of enamel, which is the hardest substance in the human body.

The brain can survive for up to 10 minutes without oxygen. The adult human brain is about three pounds. It uses 20% of the oxygen that the rest use. It also has more nerves cells than the Encyclopedia Britannica. The brain generates more electrical impulses per day than all of the telephones in the world combined.

FAQ
Is there any Hollywood blacklist for actors?
There is an Hollywood blacklist.
The list is not made public. As far as we are aware, the names are not even known. Here's why this matters.
The reason behind the secrecy was that blacklisted directors and actors wouldn't be able find work. Thus, they would leave the industry and studios will lose money. This would mean that they would cut back on movie production. This would result in fewer opportunities available for blacklisted filmmakers. Which would lead them to go bankrupt.
This could eventually lead to more victims.
In short, when someone tries to make an oscar winning movie, they might be asked to sign a contract saying they won't speak publicly against their employers. For any producer or director that wants to be nominated, the same applies.
It's no surprise that directors are often forced to take out scenes in their films by producers. Directors might threaten to leave projects that don't reflect their vision.
This is the reason there is a Hollywood blacklist. If you are negative about your employer, you'll most likely go unemployed. It's not good for anyone.
Many people have been wrongly accused. These people have had to fight to clear their names.
We must stop this from happening again. Everybody should be able to freely express themselves.
We must get rid of the Hollywood blacklist.

Have you ever wondered how much trash is produced worldwide each day?
According to the United Nations there are more than 25 billion tons of garbage produced each year.
The majority of this garbage ends up in incinerators or landfills. But what happens when the dumpsters become full? The majority of this rubbish is sent out of the country. It is then shipped out and dumped in other countries. This pollutes the ecosystems. But now we know, thanks to one man. Mike Sexton is his real name. He is the owner of Waste Watchers. His job involves monitoring the movements and routes of trash trucks across North America. Then he reports back to us about what happens next.
Sexton claims he is very satisfied with his job. CNN interviewed Sexton and said that he has a lot of fun. "You know, we see these big rigs come through town, and we'll follow them. "Sexton started following truck driver almost 20 years back.
"I just fell in love with it," he said.
His favorite story is about a driver that pulled into an abandoned gas station just outside Los Angeles. Sexton described, "The guy was looking somewhere to put his load." "He drove down the road and saw this building. He backed up and entered the building. "There were two enormous roll-off containers filled with stuff. The man took all the stuff out and filled up his truck with more. "Then he looked at the place and decided to unload everything. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was just a total mess. But it had been cleaned out before he came along. There wasn't any trash."
Why did this happen? It is because the location used to belong to a recycling centre. People who found out about this facility would drive to it to recycle their trash. Sexton said that people would bring their household items to the building and then leave empty containers behind.
Now, because of the way the law works, once a container reaches its destination, it cannot be opened.So no matter how often someone takes something out of it, the thing will never be emptied.Every time the truck comes by, it has to start over again. This could happen hundreds times per week. Finally, the truck stops running completely due to its excessive junk. The truck eventually stops running and the owner decides that it is time to get rid of the vehicle.
But, this isn't the only problem that our planet is facing.
Many of these tiny plastic pieces end up in landfills and incinerators. Some end up in rivers and oceans, while others end up in fish's stomachs.
Experts warn us that we may soon face an international food shortage if things don't change. Experts warn, "If you keep going like you're going," we could soon face a global food shortage. But most people don't seem to be worried, even though scientists are unanimous in warning us that the world is heading towards disaster.
