Question

Что происходит в носовой полости? почему дыхание через нос считается более правильным чем через рот

Answer 1

Там воздух согревается, обеззараживается специальной слизью, волоски захватывают частицы пыли и т.п.
если в холодную погоду дышать через рот, есть большой шанс простудить горло

Answer 2

What happens in the nasal cavity?

The nasal cavity is a part of the respiratory system located behind the nose. It is lined with a mucous membrane and contains structures such as the nasal septum, turbinates, and olfactory receptors. The nasal cavity plays several important roles in the respiratory process:

1. Air Filtration: The nasal cavity acts as a filter, trapping dust, allergens, and other particles present in the air we breathe. The mucous membrane and tiny hairs called cilia help to trap and remove these particles, preventing them from entering the lungs.

2. Moistening and Warming: As air passes through the nasal cavity, it is moistened and warmed by the mucous membrane. This helps to prevent the respiratory system from becoming too dry and maintains an optimal temperature for the lungs.

3. Olfaction: The nasal cavity contains olfactory receptors that allow us to perceive and distinguish different smells. These receptors send signals to the brain, enabling us to recognize and interpret various scents.

4. Resonance: The nasal cavity also plays a role in speech production by acting as a resonating chamber. It helps to modify the sound produced by the vocal cords, contributing to the quality and tone of our voice.

Why is breathing through the nose considered more correct than breathing through the mouth?

Breathing through the nose is generally considered more beneficial and healthier than breathing through the mouth. Here are a few reasons why:

1. Air Filtration: As mentioned earlier, the nasal cavity acts as a filter, trapping and removing particles from the air we breathe. Breathing through the nose helps to prevent these particles from entering the lungs, reducing the risk of respiratory infections and allergies.

2. Moistening and Warming: The nasal cavity moistens and warms the air as it passes through, ensuring that the respiratory system remains properly hydrated and at an optimal temperature. This helps to prevent dryness and irritation in the airways.

3. Nitric Oxide Production: The nasal cavity produces nitric oxide, a gas that has antimicrobial properties and helps to dilate blood vessels. Nitric oxide plays a role in regulating blood pressure, enhancing oxygen uptake in the lungs, and improving overall lung function.

4. Improved Lung Function: Breathing through the nose allows for slower and deeper breaths, which can help to improve lung function and oxygen exchange. It promotes diaphragmatic breathing, where the diaphragm muscle is engaged, leading to better oxygenation of the blood.

5. Reduced Mouth Breathing Effects: Chronic mouth breathing can lead to various health issues, including dry mouth, bad breath, dental problems, and an increased risk of respiratory infections. Breathing through the nose helps to alleviate these issues.

It's important to note that there may be certain situations where breathing through the mouth is necessary, such as during intense physical activity or when the nasal passages are blocked due to congestion. However, in general, breathing through the nose is considered more optimal for overall respiratory health.
