  Nostrils2 and Roses
鼻子在供氧过程中起着非常重要的作用,鼻子是外界氧气进入人体内部的重要通道,同时它还负责呼出体内的二氧化碳。我们可以将鼻子看作一个整体器官,但是因为鼻子的大部分功能都是在立体系统中完成的,所以我们需要两个鼻孔。
众所周知,我们有左右两个肺脏,但可能很少人知道,每一侧肺脏都是由其同侧相应的鼻孔控制的。
因此如果一个鼻孔堵塞,两侧的肺就会产生竞争,让人觉得难受、呼吸不畅。不仅如此,专关家认为两个鼻孔还能使呼吸运动更有效,进而推进整个机体的新陈代谢。用两个鼻孔透气使得每一个鼻孔可以轮换稍事休息,如果只用一个鼻孔透气,3小时就会感到疲劳。
两个鼻孔的生理结构有助于睡眠。在8小时以上的睡眠中如果保持一种睡姿不变,由于重力作用与站姿时相比发生了变化,一侧的鼻孔通常会闭塞。
因此,我们用两个鼻孔透气可以睡得更放松。由于睡眠中人对氧气的需求量减少,即使一个鼻孔暂时不通,只有另一个呼吸也不会造成呼吸不畅。
今天我们就一起听听两个鼻孔的重要性吧。

  Take a Look in the mirror and ask yourself this: why do I have two nostrils. Two eyes, sure. Two ears, ok. But why two nostrils? Wouldn’t one, big nostril1 do just as well?
Actually, no. First, one giant nostril would look really weird3. And second, although they may look identical, each nostril actually smells a bit differently. For most people, nostrils take turns swelling4 and shrinking, meaning that at any given moment the rate at which a nostril inhales6 is not equal.
Let’s say you’re taking a walk and stop to sniff7 a rose. Your swollen8 nostril inhales the tiny, microscopic9 particles released by the rose at a relatively10 slower pace than the normal nostril, which inhales at a normal clip. This is important since chemicals that enter your nose and create smell, including rose particles, come in two basic types: those that dissolve slowly and those that dissolve more quickly.
In order for slow-dissolving rose chemicals to really work they have to enter the nose at a leisurely11 pace and kind of settle down. If they’re rushed in on a fast stream of air too many pass right through the nose and don’t contribute to that unique, rosy12 smell. The rose chemicals that dissolve quickly, meanwhile, like to charge in and spread out fast in order to really pack a punch. Since they inhale5 at different speeds, your nostrils allow both kinds of rose chemicals to do their thing.
So a rose may be a rose, but in order to really smell one you need two nostrils. One big one just won’t do.
