13 Amazing Facts About Human Body - Abbaxi Writes

 HUMAN BODY

The human body is the most complex composition ever to have existed. The human body comprises all living and non-living components that create the entire structure of the human body, including every living cell, tissue, and organ.


BASIC PARTS

The human body consists of five essential parts :
1: HEAD.
2: NECK.
3: TORSO.
4: ARMS.
5: LEGS.
Beneath the skin, many chemical and biological interactions keep the human body machine ticking over.

SYSTEMS

The human body consists of different biological systems that carry out specific functions necessary for everyday living like the circulatory system, digestive system, endocrine system, etc.

CIRCULATORY SYSTEM

The function of the circulatory system is to move blood, nutrients, oxygen, carbon dioxide, and hormones around the body. The circulatory system consists of the heart, blood vessels, arteries, and veins.

DIGESTIVE SYSTEM

The digestive system consists of a series of connected organs that allow the body to break down, absorb food, and remove waste. It includes the mouth, esophagus, rectum, anus, small intestine, and large intestine. The liver and pancreas play a role in digestion because they produce digestive juices filled with enzymes that break down food components.

ENDOCRINE SYSTEM

The endocrine system comprises a network of glands that secrete hormones into the blood. These hormones, in turn, travel into different parts of the body.

FACTS ABOUT HUMANS:

The human body is a very complex organ. There are many interesting facts about the human body, but many of us don't notice those facts. When we spend time looking at what is involved in what makes us human, we realize how amazing our bodies are.


FACTS

Following are some unique and interesting facts about human bodies.

1: CONTAIN TRILLION OF BACTERIA

The human bodies consist of trillion of bacteria that help regulate inflammation and diseases. These bacteria affect our immune system and contribute to inflammatory arthritis, which affects over 430,000 people in the UK. However, some bacteria also protect our body from diseases by strengthening our immune system.

2: EYE THE FASTEST MUSCLE

The fastest moving muscle in the human body is orbicular is oculist, capable of contracting in less than 1/100th of a second. A blink typically can last 100/150 milliseconds.
We blink more when talking and less when we are reading. That is why we get tired while reading. The eye is the fastest muscle in our body which is why we say when something happens quickly in the blink of an eye.

3: 100,000 MILES OF BLOOD VESSELS

The human body consists of 100,000 miles of blood vessels. This includes veins, arteries, and communicating little capillaries that move between both. It seems like an unrealistic number, but if we imagine every single organ, a bit of skin or nerve needs its way of getting blood and taking it away, it's not surprising how much plumbing we need.

4: ONLY  2% OF HUMANS HAVE GREEN EYES

Research shows that only 2% of the population has green eyes.
Ireland, Scotland, and Northern Europe are the more significant concentration of green-eyed people.
All babies are born with blue or brown eyes. Green eyes can take six months and three years to appear in children.

5: ALL HUMANS ARE 99% IDENTICAL

All humans are 99% identical. Therefore, the visual difference or internal variations that occur in us is only due to tiny variations in genetics.
Humans are also so similar to other animals from a genetic perspective.

6: SKIN IS THE LARGEST ORGAN

The skin is the largest organ in the human body. The skin accounts for about 15 % of our weight and protects us from many diseases. It keeps everything inside from coming out, and it also helps us at the right temperature, helps with touch and sensation, allows us to move without restriction, heals and regenerates constantly, and much more.

7: WHEN WE BREATHE, WE FAVOR ONE NOSTRIL

We naturally tend to alternate from one nostril then the other as this helps keep the air we breathe moist so as not to irritate our lungs. But our bodies give one nostril a break while the other is active.

8: WE DO KNOW WHY WE YAWN

Like humans, many animals do this, and there are different theories as to why we do it. Some say it helps get more oxygen in, and others say that t helps to regulate temperature. Either we all do this, but no one knows the correct answer to why we yawn.

9: EYE REMAIN THE SAME SIZE

Eyes remain the same size thorough our entire life. Our noses and ears keep growing throughout our lives, but the vision remains the same size from birth.
Human eyes overgrow in the womb and for the first three months after birth.
By three months, our eyes have the same size that they will ever be as corneas have reached their full width.

10: WE ERASE AND REFORM OUR MEMORIES :

We imagine that when we remember an event or something in the past, it is like playing a recorded file on a computer.
But our brain rewrites the memory each time we think of it. So the childhood memories we cherish may have distorted our brains over many years.

11: TALLER IN THE MORNING:

If you ever look in the mirror in the morning, your stomach is flatter. Clothes than to hang better. Due to gravity over the daytime, our cartilage compresses to make us slightly shorter, and our organs tend to settle.

12: WE CAN'T BREATHE AND SWALLOW SIMULTANEOUSLY

This may sound obvious, but this is a deliberate evolutionary protective process that stops you accidentally.

13: EVERY SECOND, WE PRODUCE 25 MILLION CELLS:

Our body produces 25 million cells every single second. Every new cell is reproducing from the template of our DNA. This DNA template gets worn away as we age and errors occur. We then age until we can keep the template perfect; it will always happen.
