yes no your nose protects your lungs from harmful gases
Tonsils
The fumes from toilet bowl cleaners are harmful to the lungs, eyes, nose and throat. Many cleaners have corrosive ingredients and when mixed with chlorine produce dangerous fumes.
Cilia in the nose act as tiny hair-like structures that help to trap and remove harmful particles and pathogens from the air we breathe. The cilia move in a coordinated manner to sweep these particles towards the throat where they can be swallowed or expelled, thus preventing them from entering the lungs and causing damage.
don't smell harmful substances . don't smell gases used to cook .
People have hair almost everywhere on their body,nose hair is one of those parts. It grows naturally to protect dust from going into the nose and damaging the lungs.
Mucus in the nose and trachea traps foreign particles and bacteria. The cilia, tiny hair-like structures in the respiratory tract, move the mucus and trapped particles upwards to be swallowed or expelled. This process helps to protect the lungs and respiratory system from harmful invaders.
No, the nose is not part of the lungs. The nose is part of the respiratory system as it helps to filter, warm, and humidify the air before it enters the lungs, which are the primary organs for gas exchange in the body.
Mucus in the nose traps incoming particles like dust and bacteria, preventing them from entering the respiratory system. In the windpipe, mucus helps to trap and remove harmful substances that are breathed in, protecting the lungs from infection and irritation. The mucus also contains enzymes and antibodies that help to neutralize and eliminate pathogens.
The hairs in the nose help filter out dust, pollen, and other particles from the air we breathe. The epithelial lining helps trap harmful particles and also produces mucus to moisturize and protect the nasal passages. Together, these structures help keep the respiratory system healthy by preventing irritants from entering the lungs.
Air or CO2 must pass through the respiratory system, specifically the lungs. During exhalation, these gases move out of the lungs and are expelled from the body through the nose or mouth.
They breathe pretty much the same way humans do: through their nose from which the oxygen travels to the lungs where it is removed from the other gases in the air breathed in. Then the other unusable gases are expeled through their nose or mouth.
They all enter the lung ... but the only one that quickly enters the blood is oxygen. Because oxygen is the one gas that has a higher partial pressure in "lung air" than its partial pressure in the "lung blood". Note that the blood's CO2 pressure is higher than the air in the lungs, so CO2 comes out of the blood into the lung's air.
