How do lungs function

We need to breathe to stay alive and that is one of the important jobs our lungs

do to keep us alive and get rid of the carbon dioxide. Air travels through our

mouth and nose a bit like a rollercoaster. It also travels down our windpipe.

Inside the lungs oxygen enyers the blood stream and carbon dioxide is removed

and breathed out.
