These are some of the most interesting facts about our bodies. For example, an adult human's skeleton replaces itself every ten years. It has four blood categories and 206 joints. Two kidneys are also present. The human body is actually one of the most complex on the planet.
Every ten years, a adult's skeleton gets replaced.
Throughout adulthood, the human skeleton undergoes continuous remodeling and rebuilding. Bone remodeling and repair is a key function of bone cells. The body replaces nearly 100 percent its bone tissue every year. Osteoblasts, which are bone cells, break down and create new bones. This process is known as bone remodeling, and the amount of bone mineral in a bone is measured with a bone density measurement.
It has 2 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 thin, light, elastic pleural membranes act as a filter for air. They also allow air to enter the lungs through the mouth and nose.
It has two earlobes
Despite their similarities, human ears are different in size, shape, and color. The complex network that makes up the earlobe, which allows us hear and walk, is complex. The average ear size for men is larger than that 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.
FAQ

How does the brain regulate the functions of the body?
To ensure that they work together, messages are sent by the brain to other organs. Your brain controls all that happens in your body. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain consists of billions of nerve cells connected in groups called neurons. Action potentials on Axons are an electrical signal that neurons send to each other. Each neuron has a cell membrane surrounding its nucleus. Channels within the membrane allow ions such potassium and sodium to enter and leave the cells. Ion movement creates the electric charge that causes the neuron to fire.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. This causes the second neuron to fire too.
When a presynaptic nerve receives an impulse, neurotransmitter release takes place. The impulse travels along the synapse connecting the two neurons. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
They are vital for the communication between nerve cells. They are also responsible for coordinating activity between various parts of the brain.
Is there a more mysterious place than the Earth itself?
Antarctica is considered the most mysterious area on Earth.
We find this place so fascinating. Because it's unlike any other place in the world.
It is remote, isolated, and extremely difficult to visit. This site has more to it than meets your eye.
Some of the most bizarre wildlife species can also be found in this natural wonder.
Let's find out how this mysterious destination became so famous.
Antarctica, The South Pole
Antarctica's name is a mystery. Some say it means "land on 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 one source, one of the twins was conceived in winter. Therefore, the name antarctic.
Others believe the name was derived from the Greek words tropos, which means turn, and anti, meaning against. This would translate to land that is turned away from the sun.
Whatever the reason Antarctica has held a special fascination for people, it is undeniable.
It is the highest, coldest, windiest, dryest, and most populated continent. It is too cold for trees, plants and animals.
Yet, the frozen desert is alive with life.
It houses approximately 90% of all Earth's living organisms. You can find approximately half the world's species of animal and plant plants here.
And what makes Antarctica such a unique environment? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large amounts of ice to float above ground.
These glaciers are responsible for covering 80% of the continent. These glaciers are getting larger each year.
The Antarctic ice sheet has grown 60ft since 1960.
If the melting goes on, the sea level may rise by as much as 200 feet. This could lead to massive flooding across the globe.
This does not mean that everyone is wrong. 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.
However, others caution that this theory sounds a lot like a plot in a science fiction movie.
What dark secrets do Hollywood have?
Hollywood is full 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.
But there are also more nefarious organizations that control much of the industry. These include companies such as the MPAA (Motion Picture Association of America), which sets film ratings, and the RIAA (Recording Industry Association of America), which sets music licensing fees.
Numerous unions and guilds also represent actors, directors, writers, producers, etc. Most major movie studios and television networks are owned by large corporations which own these various organizations.
It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. However, we shouldn't fear them.
Instead, we should embrace and celebrate them. Because they provide us with information that helps us make better decisions.
These experts tell us which movies are most likely to succeed, which songs will be in demand, and what books will sell the best.
These help us to decide what we'll watch, read, listen, and buy.
We can trust their advice and we can ignore it if it contradicts our values.
They become more powerful because we choose to ignore them. They become the ultimate arbiters of taste.
You are free to ignore their messages if that bothers you.
Let's take a closer look at some of the less-known, yet still very real Hollywood secret clubs.
And see why they're so important.
