Question

Lungs are very important. Our right and left lungs seem to breathe by themselves. When we breathe in , our lungs are being pulled outwards by muscles in our chest. To breathe out, the muscles squeeze your chest in again. They push the hair out of our lungs.

Now, lets see how lungs work. when we breathe in, In each alveolus fills up with hair and takes oxygen from it. The oxygen molecules pass through tiny holes in the alveolus, into the blood vessels around it. These blood vessels are so small and only one blood cell can go down them at a time. Each blood cell picks up a load of oxygen as it goes past.

In return, our blood cells drop off waste for the lungs to rid of. This is mainly carbon dioxide. The waste was made by our cells as they work. It floats from the blood vessels into alveoli and up the bronchioles and comes out in your breath.

What is the text about?

a. how lungs work
b. how we breath out
c. how muscle work
d. parts of our lungs
e. how we breath in
