The mystery of the human body, why should there be two nostrils?

There are two nostrils, which are good for the nostrils to rest. We usually breathe with only one nostril, and the other nostril is in a resting state, and then work alternately, which is conducive to maintaining a warm and moist working environment in the resting nostrils.

The reason why the human body has two nostrils is to breathe better, because one nostril is threatened in survival, and it may be easily blocked and suffocated, but the two nostrils can solve this problem.

Because when we breathe, the nostrils will help us remove dust and other impurities in the air, and ensure that the air entering the respiratory tract is warm and moist, but if the nostrils are working all the time, they will be fatigued, resulting in reduced efficiency or strikes, the two nostrils are easy to do, and there is a buffer period for alternate use, so there is no need to be afraid.

Humans have 4 nostrils, and the 2 hidden "posterior nostrils" have a great effect. The function of the nose is known to help the body breathe, inhale fresh oxygen, and exhale carbon dioxide. But you may not know that the two nostrils correspond to the lungs, the left nostril corresponds to the left lung, and the right nostril corresponds to the right lung.

For example, if one nostril is blocked, that lung must compete with the other in exchange for coming from the other. Air in the nostrils.

Breathing in both nostrils helps with sleep. If you're lying on your side and hold one position throughout your sleep, one nostril tends to close due to gravity, affecting your breathing. Imagine what would happen if you only had one nostril.

Therefore, having two nostrils can make sleeping easier and more comfortable, even if one nostril is stuck in traffic and the other nose. The hole also allows you to keep breathing. Experts believe that having two nostrils also improves respiratory efficiency, which boosts overall metabolism.

Breathing through both nostrils allows each nostril to alternate and rest, but only one nostril will experience fatigue within 3 hours.

The physiology of the two nostrils also helps with sleep. If you sleep in one position for more than eight hours, one side of your nostril will usually close due to the change in gravity compared to standing. So we go through two.

Breathe in your nostrils and sleep more relaxed. If you want to say that the comfort of the car feels great, not to mention the wrapping of the seat, it is very comfortable. The appearance is a little different from the previous front face, it is a black and red grille, which gives people a more sporty feeling, the headlights are double lenses, relatively bright, and the rear taillights are also very distinctive, through-type, very special.

The power is strong, there is no feeling of slow start and slow acceleration, it is a good choice for those who require speed and the right price, and the appearance is also beautiful. Due to the reduced need for oxygen while sleeping, even if one nostril is temporarily blocked, the remaining nostrils do not cause shortness of breath.

Why do people have two nostrils? After reading the long insight!

All of this is preserved in the process of biological evolution according to the principle of eugenics, not by someone's careful design and arrangement, so there is no "why", in other words, no why. If you want to find out why, it's like explaining "Why do people have two eyes?" It's because the two eyes have a three-dimensional sense of seeing things, "Why do people have two ears?"

Because the two ears catch the sound with the same sense of direction as the sense of distance, the person has two nostrils to prevent in case one nostril is not ventilated and the other side compensates.

The nose plays a very important role in the oxygen supply process, the nose is an important channel for oxygen from the outside world to enter the body, and it is also responsible for exhaling carbon dioxide from the body. We can think of the nose as a whole organ, but because most of the functions of the nose are done in a stereoscopic system, we need two nostrils.

It is well known that we have two lungs, the left and right, but perhaps few people know that each lung is controlled by its corresponding nostril on the same side.

Therefore, if one nostril is blocked, the lungs on both sides will compete, making it uncomfortable and difficult to breathe. Not only that, but experts believe that the two nostrils can also make the breathing movement more effective, which in turn promotes the metabolism of the whole body. Ventilation through both nostrils allows each nostril to take a short rest, and if you use only one nostril to breathe, you will feel tired for 3 hours.

The physiological structure of the two nostrils helps with sleep. If you keep one sleeping position unchanged for more than 8 hours of sleep, one side of your nostril will usually be occluded due to the change in gravity compared to when you are standing.

Therefore, we can breathe with both nostrils to sleep more relaxed. Due to the reduced need for oxygen during sleep, even if one nostril is temporarily blocked, only another breath will not cause breathlessness.

Pangu opened the world, and when the apes evolved, in order to adapt to the needs of survival and ensure their own lives, they decided.

Because it's not lonely!

Why do people have two nostrils.

One can still work, but it doesn't feel good.
