MY LUNGS By Jennifer Wendt

《我的肺》詹妮弗·温特著

THE INSIDE SCOOP Your body is a super machine that keeps you moving, learning, and having fun. But how does it work? The secret is inside! Take a big breath, and let's begin!

你的身体是一台超级机器，它让你不停地运动、学习和享受乐趣。 但它是如何工作的呢？秘密就在里面！深吸一口气，我们开始吧！

When you pedal your bike really fast, you might feel out of breath. That's because your lungs are working hard to let you ride like the wind. Let's take a closer look.

当你骑得很快的时候，你可能会感到上气不接下气。 这是因为你的肺在努力工作，让你像风一样骑行。 让我们仔细看看。

LOCATING THE LUNGS You have two lungs to help you breathe. Each one takes up most of the space on either side of your chest. Your left lung is smaller than your right. It leaves room for your heart!

你有两个肺来帮助你呼吸。 每一个都占据了你胸部两侧的大部分空间。 你的左肺比右肺小。 它给你的心留下了空间！

Lungs are made up of different parts called lobes. The right lung has three lobes. And the left lung has two.

肺由不同的肺叶组成。 右肺有三个肺叶。 左肺有两个。

BREATHE IN Take a big breath. Air moves in through your nose and mouth. It travels down your throat and through a large tube called the trachea (TRAY-kee-uh). Tiny hairs in your nose and throat trap dirt from getting to your lungs.

深吸一口气。 空气通过你的鼻子和嘴巴进入。 它沿着你的喉咙，通过一根叫做气管的大管子。 鼻子和喉咙里的细小毛发会阻止灰尘进入肺部。
