Explain the three obvious 'phenomena' of people

Finding the answer to why our body temperature is 37 degrees C, sneezing can open the eyes, the appendix has "excess" .

1. Why is human body temperature stable at 37 degrees C?

Whenever the thermocouple, see the thermometer only 37 degrees C, we are completely assured of our own health. So then, have you ever wondered why it's 37 degrees Celsius and not another number like 38, 39 or 50?

The answer lies in the evolution of mankind . In the biological world, human beings in particular and mammalian families possess great abilities, surpassing reptiles: that is able to maintain body temperature at a stable level.

Humans are able to maintain their body temperature at a stable level.

That helps us to survive and outperform other species. On average, the body temperature of all mammals ranges from 30 - 40 degrees C.

According to recent scientific studies, 37 is considered the best number for development. It was found that, with an increase of 1 degree C, the risk of fungal infections decreased by 6%, and, in the range of 30-40 degrees Celsius, the most beneficial bacteria.

People need to maintain that body temperature with lots of energy.

That's why reptiles and thermoelectric organisms are very sensitive to fungi, while only a few fungal species are at risk of invading us.

One of the only disadvantages of human body heat is the need to maintain that body temperature with lots of energy. If you don't eat or drink for a long time, your energy is depleted and your body temperature will drop quickly, very dangerous to your life.

2. Why do people close their eyes when sneezing?

Sneezing is a high-level defense mechanism of the human body, but have you ever seen how you sneeze? Certainly never, because simply when sneezing, we all close our eyes.

Sneezing is a mechanism that protects the respiratory tract from foreign particles entering the nasal passages.

Why? Sneezing is a mechanism that protects the respiratory tract from foreign particles entering the nasal passages. When stimulated, the nerve center controls all contraction muscles, from the esophagus to the sphincter, of course including the eyelid muscles.

As a result, when sneezing, eyes are always closed, even some people have tears in their eyes.

Scientists come up with two hypotheses about this problem: it may show the interconnection of parts of the body, or that combination of protection of the nasal and eye lines: because when sneezing, about 100,000 bacteria and put pressure to release at a speed of about 160km / h.

Maybe if you don't close your eyes, people will be blinded to the point of . flying out?

3. Why do humans have appendix?

Many of us have experienced the sensation of a latent bowel pain: pain from day to day. Humans are the most evolved creature on the planet, why possess a 'useless' part like that?

The appendix, similar to wisdom teeth, is one of the vestiges of human evolution from ancient gibbons.

In fact, they don't 'eat without sitting' . The appendix, similar to wisdom teeth, is one of the vestiges of human evolution from ancient gibbons.

Many scientists have shown that the appendix is ​​the part used to digest the leaves of ancient primates, but since humans advanced to civilization, its main function gradually dissipated and it existed for To this day another task is to contain many white blood cells against infectious diseases and support the small intestine.

The appendix is ​​the part used to digest leaves of ancient primates.

In theory, human evolution will continue, but at a very slow pace. Most likely, the appendix will disappear forever, but as experts estimate, it will be a beautiful day of 100,000 years later.
