《我的肺》 作者：瑞秋·赖斯 插画：雷米·西马尔 核心问题 肺是怎么帮助你的身体获取氧气的呢？

My lungs are part of a system that keeps me alive. My lungs help my body get the oxygen it needs.

我的肺是维持我生命运转的系统的一部分。 我的肺帮我的身体获得它所需的氧气。

Oxygen comes from the air I breathe. My lungs pull oxygen from the air with each breath.

氧气来自我呼吸的空气。 每一次呼吸，我的肺都会从空气中提取氧气。

Each breath comes into my nose or mouth first. My nose and throat warm up and clean the air. Tiny hairs in my nose and throat do the cleaning.

每次呼吸的空气首先进入我的鼻子或者嘴巴。 我的鼻子和喉咙会把空气加热，还会清洁空气。 清洁工作是我鼻子和喉咙里的细小绒毛做的哦。

The air moves down my throat into my two lungs. It moves through tubes in my lungs that branch like trees.

空气顺着我的喉咙往下，进入我的两片肺里。 空气穿过我肺里像树枝一样分叉的管道。

The tubes end in tiny sacks that look like bunches of grapes. The tiny sacks are like balloons.

管道的尽头是看起来像一串串葡萄的小囊。 这些小囊就像小气球一样。
