THE TOP 10 AMAZING FACTS ABOUT THE HUMAN BODY THAT WILL BLOW YOUR MIND

Amazing Facts About The Human Body That Will Blow Your Mind

The human body is a complex and fascinating machine that performs countless functions every day. It is also full of surprises and secrets that most of us are not aware of. In this article, we will reveal some of the most amazing facts about the human body that will blow your mind.

1. You have more bacteria than cells in your body

Did you know that you are not alone in your body? You are actually a host to trillions of microorganisms that live on and inside you. These bacteria, viruses, fungi, and other microbes outnumber your own cells by a ratio of 10 to 1. They form a diverse and dynamic community called the microbiome, which plays a vital role in your health and immunity. Some of these microbes are beneficial, while others can cause diseases. The balance and diversity of your microbiome can affect your mood, weight, digestion, and even your personality.

2. You can survive without many organs

The human body has many organs that perform various functions, such as the heart, lungs, liver, kidneys, and brain. However, not all of them are essential for survival. You can actually live without some of them, or with only a part of them. For example, you can survive with only one kidney, one lung, one ovary or testicle, 75% of your liver, 80% of your intestines, and almost half of your brain. Of course, this does not mean that you should donate or remove your organs, as it can affect your quality of life and health. But it is amazing to know that the human body can adapt and function with less than what it was designed for.

3. You have a hidden organ in your body

Speaking of organs, did you know that you have a hidden organ in your body that was only discovered recently? It is called the interstitium, and it is a network of fluid-filled spaces that surrounds your tissues and organs. It was previously thought to be just connective tissue, but scientists found out that it is actually a distinct organ that acts as a shock absorber and a source of lymph, the fluid that carries immune cells. The interstitium may also play a role in cancer spread, inflammation, and aging.

4. You have a second brain in your gut

You probably know that your brain is the control center of your body, but did you know that you have a second brain in your gut? It is called the enteric nervous system, and it consists of about 100 million neurons that line your gastrointestinal tract. It can function independently from your central nervous system, and it is responsible for regulating your digestion, motility, secretion, and blood flow. It also communicates with your brain via the vagus nerve, and influences your emotions, memory, and behavior. This is why your gut is often referred to as your "second brain" or your "gut feeling".

5. You can produce enough saliva to fill two bathtubs in a year

Saliva is a watery substance that is produced by your salivary glands in your mouth. It helps you moisten your food, digest your starch, protect your teeth, and fight germs. It also contains enzymes, hormones, antibodies, and other substances that can reveal information about your health and genetics. You may not notice it, but you produce a lot of saliva every day. On average, you produce about 1.5 liters of saliva per day, which is enough to fill two bathtubs in a year. That's a lot of spit!

6. You can see your nose all the time, but your brain ignores it

Your nose is one of the most prominent features on your face, but you don't usually see it. That's because your brain filters it out from your vision. Your nose is always in your field of view, but your brain ignores it because it is not relevant to your focus. This is an example of sensory adaptation, which is the ability of your brain to adjust to constant stimuli and pay attention to changes. However, you can still see your nose if you cross your eyes, or look at a bright light and then close your eyes.

7. You can't tickle yourself

Tickling is a sensation that is caused by a light touch on your skin, especially in sensitive areas like your armpits, feet, or sides. It can make you laugh, squirm, or feel uncomfortable. But you can't tickle yourself, because your brain knows that it is you who is doing it. When you try to tickle yourself, your brain anticipates your touch and reduces the response of your tickle receptors. This is why you don't feel the same ticklish sensation as when someone else tickles you. However, some people can tickle themselves if they use a tool, such as a feather, or if they have a disorder, such as schizophrenia, that affects their sense of self.

8. You can't sneeze with your eyes open

Sneezing is a reflex that is triggered by an irritation in your nose or throat. It is a way of expelling foreign particles, allergens, or germs from your respiratory system. When you sneeze, you also close your eyes involuntarily. This is because your sneeze and your blink are controlled by the same cranial nerve, the trigeminal nerve, which sends a signal to your brain to activate both actions. It is possible to sneeze with your eyes open, but it is very difficult and unnatural. Contrary to popular belief, your eyes will not pop out of your sockets if you sneeze with them open.

9. You have a unique tongue print

You probably know that your fingerprints are unique, and that they can be used to identify you. But did you know that your tongue print is also unique? Your tongue has a distinctive shape, size, texture, and pattern of bumps and grooves that make it different from anyone else's. Your tongue print can also reveal information about your health, such as your hydration, nutrition, and infection status. However, unlike your fingerprints, your tongue print is not easy to capture and analyze, and it can change over time due to factors such as aging, injury, or disease. Therefore, it is not widely used for identification purposes.

10. You have a natural sunscreen in your skin

Your skin is the largest and most exposed organ in your body. It protects you from various environmental factors, such as temperature, moisture, and radiation. One of the ways it does this is by producing a natural sunscreen called melanin. Melanin is a pigment that gives your skin its color, and it also absorbs and reflects ultraviolet (UV) rays from the sun. The more melanin you have, the darker your skin, and the more protection you have from sunburn and skin cancer. However, melanin is not enough to protect you from the sun completely, and you still need to apply sunscreen and avoid excessive sun exposure.
