It is fascinating to discover bizarre facts about the human body. One example: A human adult's skeleton is replaced every ten year. It has four blood categories and 206 joints. We also have two renal systems. The human body is actually one of the most complex on the planet.
The adult human skeleton changes every ten year
The human skeleton goes through continuous remodeling and reconstruction throughout life. Bone cells play a vital role in bone repair and remodeling. Nearly 100 percent of bone tissue in a person's body will be replaced over the course of their lives. Bone cells are called osteoblasts, and they break down old bones and form new ones in their place. This is called bone remodeling. A bone density measurement measures the amount of bone mineral within a bone.
It has two lungs
The human body has two lungs, or lobes, that are located in the chest cavity. These organs exchange oxygen and remove carbon dioxide. Each lung is protected by a membrane known as a pleura. The main bronchus connects the pleura to the heart and the trachea. Pleural membranes, which are thin, light and elastic, provide an air filter system. They also allow air in the lungs to flow through the nose, mouth, and nose.
It has 2 earlobes
Despite the similarities between them, human ears can be quite different in terms of their size, shape and color. The complex system of structures within the earlobe enables us to hear and move. Men's ears are usually larger than those of women. The average ear length is 2.5 inches, and the ear lobe is 0.74 inches long and 0.77 inches wide. According to studies, the ear lobes grow larger as we age.

Five interesting facts about your liver.
The liver is responsible in breaking down toxins, storing vitamins and mineral, and for regulating blood pressure. It regulates blood pressure and maintains a stable body temperature.
Is it not often that we hear people say "I feel sluggish today" and "my head feels heavier?" These symptoms may indicate problems with the liver.
Some common signs include dark urine, yellowing skin, fatigue, nausea, vomiting, loss of appetite, stomach cramps, jaundice (yellow coloration), and itching. These are not the only warning signs. If you experience any of them, make an appointment with your doctor immediately.
The liver, an essential organ, is vital. It is responsible for detoxification as well digestion, metabolism and immunity.
-
An adult liver weighs around 1,400 grams.
-
At birth, a baby's liver is half the size of an adult. It grows to be about four times bigger by age three than an infant's.
-
The liver can be found on the left side of your abdomen, just below the lower rib cage.
-
There are 16 main lobes in the liver, but many smaller lobules are inside the lobes.

What is one of the most amazing facts about the human 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.
A heart is a pump, which circulates blood throughout our bodies. 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 heart is constantly pumping blood, 24 hours a week, 365 day a year. While you sleep, your heart beats almost 100 times per minute.
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. The skin turns purple or blue when there is a blockage in blood flow.
Red blood cells are missing in people with sickle-cell disease. Their blood becomes sticky and hardens, causing them to become very ill.
A bandage can be used to stop bleeding if you have cut your own skin. Blood must continue to flow to allow the wounds to heal properly. Doctors will insert a needle under the skin to access the vein near the injury. This allows blood flow to the area that has been injured.
Doctors can also insert catheters into the artery close to the area where the bloodclot has formed. This keeps patients alive until the clot has broken up naturally.
Is there any Hollywood blacklist for actors?
There is an Hollywood blacklist.
The list is not made public. As far as we know, the names aren't even known. But here's why it matters.
The secret is because the directors and actors on blacklist wouldn't have any job opportunities. So they'd go out of business, which means that the studios would lose money. It would mean they would reduce their expenditure on movies. The blacklisted filmmakers would have fewer chances. This would make them bankrupt.
This could eventually 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. Producers and directors who want to be nominated are subject to the same restrictions.
This is why you'll hear about directors being pressured by producers to take scenes out of their films. Or how directors threaten to walk away from projects that don't fit their vision.
This is why Hollywood has created a blacklist. If you make negative comments about your employer, it's likely that you will be unemployed. This is not good news for anyone.
The problem is that many people have been falsely accused. It's been a struggle to get their names cleared.
This is unacceptable behavior and must be stopped. Everybody should be able to freely express themselves.
Therefore, it is necessary to eliminate the Hollywood blacklist.
What is the most mysterious area on earth?
Antarctica is considered the most mysterious area on Earth.
Why do we find this place so intriguing? 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.
This natural wonder is also home to some of the strangest wildlife species.
Let's now see how this amazing destination came to be so well-known for its mystery.
Antarctica: The South Pole
It is not known why Antarctica was called Antarctica. Some believe it means "land of ice." Others believe it derives from Greek mythology.
Antarktis is the name Antarktis was given to an island in ancient Greece by Zeus' twin brothers. According to some legends, one of these twins was born in winter. The term antarctic is derived from this.
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 held a special fascination for people, it is undeniable.
It is the coldest, windiest, driest and highest continent. Because it is too frigid, there are no trees, animals, or plants.
And yet, this frozen wasteland is teeming with life.
It is home to approximately 90 percent of all life on Earth. It is home to approximately half of all world's animal and plant species.
What is Antarctica? Here water freezes to ice and not evaporates into the atmosphere.
This causes large ice masses to rise above the ground.
These floating glaciers make up 80%. And they're growing larger every year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
The sea level will rise up to 200 feet if melting continues. This could lead worldwide flooding.
This is not necessarily bad news. Some scientists suggest that global warming could actually be good for us. 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.
Others warn that this theory sounds like something out of a science-fiction movie.
