Why is the human nose able to remember 50,000 gases?

Because the nose transmits through like the brain, so that the brain remembers.

Because it's the work of the sensing organs in the human nose.

The human nose has a lot of smelling spots, and memory.

It's so that we can live better.

A human nose is not as sensitive as a dog's, but it can still remember 50,000 scents.

Identify dangerous large carnivores, even according to humans.

It is the human brain that can remember the ears and nose.

It's not our nose that remembers smells, it's our brains.

Our nose is a complex chemosensory system made up of smell and taste.

The nose is a complex chemosensory system, so it can be done.

Because there are many, many olfactory nerves here.

Because the human nose is well developed and sensitive.

I haven't smelled 50,000 gases myself.

This is determined by the person's genes.

This is determined by the physiology of the person.

Because humans are amazing beings.

Because the word foodie is not covered.

Maybe the nose is more awesome, I don't know.

Because the sensitivity of the human sense of smell to each gas varies greatly, of course, not all of them are the higher the concentration, the stronger the feeling, and the characteristics of each gas are different.

Therefore, it must be analyzed on a case-by-case basis.

That's too technical, and in layman's terms, there are olfactory cells in the nose, and the olfactory cells sense the smell and transmit it to the brain through the nerves!

1. The nose plays a very important role in the process of oxygen supply, the nose is an important channel for external oxygen to enter the human 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 the stereoscopic system, we need two nostrils.

2. As we all know, we have two lungs, the left and right, but probably few people know that each lung is controlled by its corresponding nostril on the same side.

3. Therefore, if one nostril is blocked, the lungs on both sides will compete, making people feel uncomfortable and breathless. 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.

4. The physiological structure of the two nostrils helps in 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.

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

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

Because the nose is the organ of smell!

This is a normal physiological phenomenon with different control of the left and right brains. You can try it, which nostril you use to breathe when you just wake up and don't make big movements, which nostril you use to breathe after a lot of exercise, and which nostril you use to breathe after mental work, are all different.

Because the nasal hairs in the nose filter the air and reduce pollution.

People originally breathe through one nostril, and it changes every 7 hours.

Because if you breathe less than one nostril, you will be suffocated.

The person breathes with most of the right hole when he is nervous and the left hole when he is calm.

It's uncomfortable, don't you feel like you live upstairs?

I breathe through both nostrils.

Why don't you breathe together with both nostrils?

I breathe through one nostril. It's uncomfortable!

I didn't notice this problem, so I deliberately plugged a nostril...

It was so uncomfortable that I changed my nostril to another nostril and it was the same.

So I knew, at least I wasn't breathing through one nostril.
