Coughing do not filters the air. Particles from air are deposited on mucus membrane of bronchial tree. But coughing takes out the particles deposited there.
Air inhaled through the mouth is not as clean as air inhaled through the nose. Reason for this is that when we inhale air through our nose than it get filtered by hair present in our nose. But air inhaled through our mouth goes directly in without any filtration.
Coughing while throwing up acts just like a gag reflex. Its there to help prevent Aspiration Pneumonia... which is inhaling something that isn't supposed to be inhaled like food, liquids, saliva and vomit virtually anything that isn't air. Coughing will help to keep it from getting into your lungs... its another defence mechanism the body has.
If you have inhaled bleach, move to an area with fresh air immediately. If you are experiencing symptoms like difficulty breathing, coughing, or throat irritation, seek medical help promptly. Treatment may involve providing oxygen therapy, medications to help with breathing, and monitoring for any potential complications.
Air should be inhaled through the nose so that it can be warmed up to body temperature before entering the lungs. Despite this, it is perfectly possible to breathe in through the mouth, as the airways are linked to both the nasal passage and the buccal cavity (posh name for the mouth).
Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
Inhaled air is typically warmed and humidified as it passes through the nasal passages. The purpose of this process is to protect the delicate tissues of the respiratory system from damage due to cold and dry air.
Air purifiers help with paint fumes by filtering out harmful chemicals and particles in the air, reducing the strong smell and improving air quality in the room.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Your nasal cavity is responsible for both moistening and warming the air that is inhaled. It is also responsible for filtering dust and other fine particles out of the air before they reach your lungs (that's what your boogers are.)
When gum is inhaled, it typically lodges in the lungs, specifically in the airways or bronchi. Unlike food, which can be swallowed and digested, gum is not broken down by the body and can create a blockage if it obstructs the air passages. This can lead to coughing or respiratory distress, and it may require medical attention to remove it.
It has small dense hairs lining it that trap small debris, thus filtering the air.
In the lungs it's called cilium, plural cilia.
