Inhaled air is warmed and moistened in the nasopharynx and oropharynx.
As air enters the respiratory system through the nose, it is warmed, filtered, and moistened. These changes increase the efficiency of gas exchange in the lungs, and protect the lungs from particulates.
warmed, moistened and cleaned by the nose and mouth
The inhaled air 'swirls' around the conchaemoistens via the mucus secreted by the goblet cells and drainage from the nasolacrimal ducts; cleans by the mucus trapping dust particles and the cilia moving the mucus and trapped dust particles toward the pharynx
air is filtered, warmed, and moistened.
In the lower respiratory system, air that has been filtered of pathogens and warmed in the upper respiratory tract is transported to the lungs. There, oxygen will be pulled from the inhaled air and deposited into the bloodstream, while carbon dioxide pulled from the bloodstream is released back into the lungs to be expelled from the body upon exhaling. This exchange of gases is the primary function of the respiratory system.
Yes
The nose is the first cleaned and moistened warm part of the respiratory system. The nose acts as a filter for air to get to the lower respiratory system.
There are a few key reasons why the air you breathe in needs to be warmed in the nasal cavity. It will shock your system and cause vessels to constrict if not warmed for example.
so that it doesnt harm the delicate tissue inside the lungs. the same as humans
As air passes along the upper respiratory tract, it is warmed, moistened and filtered. The mucous membranes and cilia help these processes.
Inhaled air will be of ambient temperature. If the surroundings are warm, then inhaled air is warm. If surroundings are cold then inhaled air is cold.
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).
