Weird facts about the human body are fascinating to learn. The adult human skull is capable of replacing itself approximately every ten-years. There are four blood types and 206 bones. Two kidneys are also present. The human body is actually one of the most complex on the planet.
Every ten years, the adult human skeleton is replaced.
The human skeleton goes through continuous remodeling and reconstruction throughout life. Bone remodelling and repair are made possible by bone cells. Over the course of a human's life, nearly 100 percent of the bone tissue in his or her body is replaced. Osteoblasts is a term for bone cells. They are responsible for breaking down old bones and forming new ones. This process, known as bone remodeling is measured using a bone density measurement.
It has two lungs
Two lungs (or lobes) are found in 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. Pleural membranes are thin, light, elastic, and provide a filtration system for air. They allow air through the nose and mouth to reach the lungs.
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. Men's ears are typically larger than women's ears. The average length of an ear is 2.5 inches. The ear lobe measures 0.74 inches in length and 0.77 inches in width. Studies show that the size of the earlobes increases with age.

How does the brain control the functions of your body?
The brain relays messages to other parts of the body to ensure their functionality. Your brain controls all that happens in your body. It tells you your stomach to digest food; your lungs to inhale air; and it tells you your arms and legs how to move.
Your brain is made of billions, or neurons, of nerve cells. Action potentials are electrical signals that neurons send to one another. Each neuron has its own cell membrane around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. The neuron fires when there is ion movement.
When a neuron is activated, neurotransmitters release chemicals into the space between it and the next neuron. Neurotransmitters attach to the receptors of the second neuron and open ions channels for ions to pass in and out. The second neuron also fires.
Neurotransmitter production occurs when a neuron in the presynaptic receives an impulsive signal from another. 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.
Communication within the nervous system is possible thanks to neurotransmitters. They also help coordinate activity between different parts of the brain.
Have you ever wondered what amount of trash is generated each day worldwide?
According to the United Nations, the average person produces over 2.5 pounds of daily waste.That adds up to over 25 billion pounds of garbage per year!
Most of the trash ends up at incinerators and landfills. But, what happens to those dumpsters? Most of that trash is shipped 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 nickname. He runs a company called Waste Watchers.He spends his days watching the movements of trucks transporting trash across North America. He then reports back 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 began following truck drivers almost 20 years ago.
He stated, "I just fell in Love with It."
His favorite story involved a driver who pulled off at an abandoned gas station near Los Angeles. Sexton said that the man was searching for a place to store his stuff. "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 guy took everything out and started filling up the truck again. "The man looked around the area and decided to unload all of it. There were a bunch of old tires, rags, furniture, mattresses, boxes, bottles, cans, and whatever else. "It was a complete mess. But it was cleaned out before he came. There wasn't any trash anywhere."
So why did this happen? It's because this area used to be a recycle center. People would drive from all over the country to recycle their trash. "They'd bring their household items and take them to this building," Sexton explained.And after they finished, they would leave the empty containers behind.
This can happen hundreds of times a week. It could happen hundreds of thousands of times a week. The truck eventually stops running because it has become so jammed with junk. The owner finally decides to stop using the truck.
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 warn us that we may soon face an international food shortage if things don't change. "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.
