鼻子是呼吸道的门户,吸入空气中的氧气,呼出二氧化碳,进行气体交换,维持生命。但大多数吸入空气的温度、湿度并不十分理想,常常还混有微小的尘埃和有害物质,不宜直接吸入肺泡。人们也许想不到,鼻腔的特殊解剖结构还有对吸入空气的调温、保湿、过滤和清洁的作用。 Nose is the gateway to the respiratory tract, inhaling oxygen in the air, exhaling carbon dioxide, gas exchange, and life. However, most of the inhaled air temperature and humidity is not very satisfactory, often mixed with tiny dust and harmful substances, should not be directly inhaled alveoli. One may not expect that the special anatomy of the nasal cavity also has the effect of regulating the temperature, moisturizing, filtering and cleaning of inhaled air.
