鼻对吸入空气加温和湿化的调节作用是在空气流经狭窄的、富于血管、粘膜腺体和杯状细胞的鼻腔时实现的。由于鼻腔前部温度较低,呼出的气流被浓缩,因而鼻腔还有回收热能和水份的作用。在正常情况下,腺体和杯状细胞湿化空气的能力很大,即使空气湿度很低,亦能保持鼻粘膜纤毛活动能力不受影响。有实验表明,将观察对象放在湿度相当于10％的环境中持续观察78小时,仍多能保持鼻粘膜纤毛完好的活动力。鼻腔因具粘液纤毛系统而有良好的清除和过滤机能,可防止有害的颗粒、气体和微生物深入其下之呼
The regulatory role of the nose in warming and humidifying the inhaled air is achieved when the air passes through the nasal cavity of narrow, blood vessels, mucosal glands and goblet cells. Due to the lower temperature in the anterior nasal cavity, the exhaled air stream is concentrated and the nasal cavity also has the effect of recovering heat and water. Under normal conditions, glands and goblet cells have a great ability to humidify the air and maintain the nasal mucociliary activity unaffected even if the air humidity is low. Experiments show that the observation object on the humidity equivalent to 10% of the environment continued to observe 78 hours, still able to maintain the mucosal cilia intact activity. Nasal mucus cilia system due to a good removal and filtration capabilities to prevent harmful particles, gases and microbes under the call
