求一些描写关于肺的功能的英文
The lung is a magnificent organ that performs a multitude of vital functions every second of our lives.Breathing is the most essential of these functions.With each breath,the lungs take in oxygen and remove carbon dioxide.
The air (oxygen) we breathe enters the lungs via the main windpipe (trachea),which branches into two main tubes supplying the right and left lung,respectively.These tubes progressively branch 22 additional times to form more than 100,000 smaller tubes (bronchi,bronchioles) and more than 300 million air sacs (alveoli),which are only about 0.3 mm in diameter.
后面还有,我就不过多复制了,具体可以参考我提供的链接.
