Weird facts about the human body are fascinating to learn. An adult human's skull replaces itself about every tenth of a century. It has four blood categories and 206 joints. We also have two kidneys. The human body is among the most complicated on Earth.
Every ten years, the adult human skeleton is replaced.
The human skull undergoes constant remodeling and rebuilding through adulthood. Bone cells play a vital role in bone repair and remodeling. The body replaces nearly 100 percent its bone tissue every year. Osteoblasts are bone cells that break down bones to make new ones. This process is called bone remodeling. The bone density measurement is used to measure the amount bone mineral in a given bone.
It has two lungs
Two lungs in the human body, called lobes or lungs, are located within the chest cavity. These organs are responsible both for exchanging oxygen and removing carbon dioxide. The membrane that covers each lung is called the pleura. It is connected by the mainbronchus to the heart, trachea and lungs. The pleural membranes provide air filtration. They are thin, flexible, and light. They allow air through the nose and mouth to reach the lungs.
It has two ears
Despite sharing many similarities, human ears differ in their size, shape, color, and appearance. The complex system of structures within the earlobe enables us to hear and move. The ears of men are generally larger than the ears of women. The average ear length, at 2.5 inches, is 0.74 inches and 0.77 inch respectively. The ear lobes get larger with age, according to studies.

Is there a Hollywood blacklist?
There is a Hollywood blacklist.
The list isn’t available for public viewing. The names are not known to us. But, here's why it matters.
The secretive nature of the information is due to the fact that actors and directors on blacklist won't be in a position to find work. The studios would be out of business as they lose money. It would mean they would reduce their expenditure on movies. This would lead to fewer opportunities and less money for blacklisted directors. This would make them bankrupt.
This could lead to more victims.
When someone tries making an Oscar winning movie they might be asked for a contract. This means that they can't publicly criticize their employer. For any producer or director that wants to be nominated, the same applies.
You hear stories of directors being pressured to remove scenes from films. Or directors threaten to walk out of projects that don’t match their vision.
This is why Hollywood has created a blacklist. Negative comments about your employer will most likely lead to you being unemployed. This is bad news for anyone.
It is not uncommon for people to be falsely accused. They've had the toil to clear their name.
This kind of thing must stop before it can happen again. Everyone should have the right to speak freely.
Also, we must take down the Hollywood blacklist.
What is the most surprising fact about your body?
Two eyes, two ears and two nostrils are part of our bodies. We also have four limbs: a mouth, nose, penis, and four limbs. It's true, we have more 50 parts of our body, but there is one thing missing. A heart.
The heart is a pump which circulates blood throughout the body. The blood flows through the veins and arteries to carry oxygen and nutrients to the cells.
The heart pumps out approximately 5 liters of blood per minute. This is equivalent to a person drinking 2-3 cups coffee daily.
The heart is constantly pumping blood, 24 hours a week, 365 day a year. While you are sleeping, your heart beats about 100 times per second.
Color of your skin is a good indicator of whether someone is healthy. If you examine the skin closely, you will see tiny blood vessels called capillaries. These vessels carry blood back to the heart from the large blood vessels beneath the skin. If blood flow is blocked, skin can turn blue or purple.
People with sickle cells lack red blood cell. Patients with sickle cell disease have their blood become sticky and harden, leading to severe illness.
If you cut yourself, a bandage is applied to stop the bleeding. For the wound to heal properly, blood must continue to flow. To do this, doctors will insert a needle through your skin into the vein adjacent to the injury. This allows blood drainage from the injury area.
Doctors can also insert catheters into the artery close to the area where the bloodclot has formed. This keeps the patient occupied until the clot is broken down naturally.
What are the darkest secrets of Hollywood?
Hollywood is full of secret societies. There are many secret societies in Hollywood. Some are cult-like, where members adhere to strict rules and rituals. Others are clubs for people who share similar interests.
However, there are many other criminal organizations that hold much of the industry's power. Companies such as the MPAA, which determines film ratings, or the RIAA (Recording Industry Association of America), that set music licensing fees, are examples of these.
Numerous unions or guilds also represent producers, writers, actors, etc. The majority of major television networks and movie studios are owned by large corporations.
It is obvious that, no matter how secretive or obtuse a group appears, someone knows exactly what they do. We shouldn't fear these people.
Instead, we should embrace them. Because they offer us information that can help us make better decision.
They also tell us about the movies that are most likely to succeed and which songs are most popular.
They help us make decisions about what we will buy, watch, listen to, or read.
Because we can trust them, we can ignore their advice when it conflicts with our tastes.
They are more powerful than ever because we chose to ignore them. They become the ultimate arbiters for taste.
You are free to ignore their messages if that bothers you.
Now let's take a look at some lesser-known yet very real Hollywood secret society.
And you'll understand why they're so crucial.

Secret societies and clubs in American history
American History is fascinating because of many reasons. They are mysterious because of this. Their impact on our society is another reason.
Secret societies and clubs have been used throughout America’s history in order to promote ideas that might otherwise be considered taboo. These ideas include antisemitism or racism. These groups also promoted political ideologies such communism, socialism, and other socialist ideas.
The most famous organization in American history is the Ku Klux Klan. This group was formed in 1865 after the Civil War ended. Its mission was to protect white males from African Americans.
Other organizations created during this period included the Knights Templar, Freemasons, and Odd Fellows. These groups had the same goals and beliefs.
Another interesting aspect of secret societies is that they often had memberships restricted to males only. However, some women belonged to these groups. These women included Emma Goldman (Margaret Sanger) and Susan B Anthony.
There were other secret societies that did not share these ideals, in addition to those mentioned. The Order of Skull & Bones, for example, was established in 1832. Their goal was to create an elite group within the United States.
