Strange and Weird Facts about the Human Body

You can discover many interesting facts about the human body, whether you are a scientist or just a curious layperson. There are thousands, if not millions, of biological systems in the body. Each one has a unique purpose. The human body can be described as a vast and complex wonderland. 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 during the Big Bang 13 billion years ago. The human body has 39 trillion cells in its microbial biome.

Teeth make up the skeletal system of the body. There are about 32 teeth on an adult's teeth. Teeth are not considered to be bones but are part of the bone system. The hardest substance found in the human body, enamel is used to make teeth.

The adult human heart beats around 36,500,000x a year. An adult's average blood supply is five liters. The adult bladder can hold 16-24 ounces urine. Most people draw their lungs as the same size. The surface area for adult human lungs measures 70 square metres.

There are more than 600 skeletal bones in the human body. Each muscle is composed of two parts. There are muscles that pull in opposite directions. 20 tons of force is contained in the human body. The heart is the only muscle that doesn't tire. The human eye has 2 million working parts, and can differentiate 10 million colors.

25 million cells can be produced by the human body every second. It produces enough heat in 30 seconds to boil half a gallon worth of water. It also produces heat for the digestion of food. This heat is used to maintain body homeostasis. The heart can pump enough blood to reach 30 feet.

There are 100,000 miles of blood vessels in the human body. The circulatory system is made up of the heart, arteries, veins, and capillaries. It circulates oxygen, carbon dioxide and nutrients throughout the body. It also removes waste from our bodies. The kidneys filter out two quarters of the waste from the body.

The human nose is capable of recognizing 50,000 different scents. It also generates enough electricity that it can light a bulb. The human eye can detect ultraviolet light.

The brain, the largest organ in the body of a human being, is the human brain. It is home to 100 billion nerve cells. The adult brain uses more oxygen than the rest of the body. The brain can survive for up to 10 minutes without oxygen. The adult human brain weighs three pounds. It uses about 20% of the oxygen the rest of the body does. It also contains more nerve cells that the Encyclopedia Britannica. The brain generates far more electrical impulses daily than all the phones in the world.

Over 500 functions can be found in the human body. Some of these functions include the ability to digest food and filter out waste. The liver is often referred to as the "chemical factory of the body".

FAQ

Here are 5 fascinating facts about the liver

The liver is responsible in breaking down toxins, storing vitamins and mineral, and for regulating blood pressure. It helps maintain a steady body temperature and regulates blood pressure.

How often do we hear someone say, 'I feel sluggish today' or 'my head feels heavy'? These symptoms could be signs of liver problems.

Other symptoms include itching, yellowing of the skin, heavy urine, yellowing of the skin, fatigue and nausea. These are not all the warning signs. If you experience any of them, make an appointment with your doctor immediately.

The liver is an essential organ. It is responsible for detoxification as well digestion, metabolism and immunity.

1. An adult liver weighs around 1,400 grams.
2. At birth, the liver of a baby can be half as big as an adult's. It becomes about four times more large by the age of three than an infant's liver.
3. The liver is located on the left side, just below your rib cage.
4. There are 16 main lobes in the liver, but many smaller lobules are inside the lobes.
5. The liver contains about 10 million individual red blood cells.

Is there a Hollywood blacklist of actors?

There is a Hollywood blacklist.

However, the list isn’t public. As far as we are aware, the names are not even known. This is 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. 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. They would then 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. This applies to any producer or director who wishes to be nominated.

This is why you'll hear about directors being pressured by producers to take scenes out of their films. Directors may threaten to quit projects that don’t align with their vision.

This is why Hollywood has created a blacklist. If you speak negatively about your employer, you will likely be fired. This is bad news for anyone.

Problem is, many people have been falsely charged. These people have had to fight to clear their names.

This is unacceptable behavior and must be stopped. We need to ensure everyone has the right of expression.

Also, we must take down the Hollywood blacklist.

How does the brain control the functions in your body?

The brain relays messages to other parts of the body to ensure their functionality. Everything in your body is controlled and managed by your brain. It tells your stomach to digest food and your lungs to breathe air; it tells your arms and legs to move.

Your brain is made up billions of nerve cell networks connected in groups known as neurons. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Each neuron is covered by a cell membrane. 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.

Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters are able to bind to receptors in the second neuron. This opens ion channels that allow ions to flow in and out. The second neuron also fires.

Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. An impulse travels along a synaptic link between the two neuron. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.

For communication within the nervous systems, neurotransmitters are essential. They are also responsible for coordinating activity between various parts of the brain.

What is the most intriguing fact about the human anatomy?

There are two eyes, two ears. Two nostrils. Four limbs. A mouth, nose and penis. We have over 50 parts of our bodies. However, one thing is missing. A heart.

The heart is a pump which circulates blood throughout the body. The blood moves through the veins. It transports oxygen and nutrients to your cells. It also removes carbon dioxide.

The heart pumps about 5 liters blood per minute. This is equivalent to a person drinking 2-3 cups coffee daily.

The blood flows throughout the heart 24/7, 365 days a calendar. While you are sleeping, your heart beats about 100 times per second.

Because of the color and texture of their skin, you can tell if someone is healthy or sick. Capillaries are tiny blood vessels visible on the skin's surface. These small vessels carry blood away from the large blood vessels in the skin back to the heart. The skin turns purple or blue when there is a blockage in blood flow.

People suffering from sickle cell disease have no red blood cells. They become very sick when their blood becomes hardened and sticky.

You can use a bandage to stop bleeding if your cut is severe. For the wound to heal properly, blood must continue to flow. Doctors place a needle in the wound and insert it through the skin. This allows the blood from the injured area to drain.

A doctor can also insert tubes (catheters), into an artery in the vicinity of where blood clots form. This keeps the patient occupied until the clot is broken down naturally.
