are the organs of the body through which we breathe.
Have you ever tried to blow a balloon. You huff and you puff and
blow the air in to make the balloon bigger. And when you let go
off it then, the air just rushes out as the balloon deflates back
to its original size. That is exactly how the lungs function. You
have to make an effort to breathe in and air enters your lung whereas
breathing out occurs on its own due to the elasticity of the lungs.
breathe through our nose, the air passes through the windpipe into
the lungs. Our lungs are made up of small tubes and still smaller
balloons so that we can breathe in all the possible fresh air as
we breathe, the body takes in the oxygen that it needs and removes
the carbon dioxide that it doesn't need.
The oxygen from the lungs enters the blood through which it is distributed to all the organs of the body and carbon dioxide from the blood enters the lungs and is given out as we exhale.
Thus, without our lungs, we would not be able to survive even for
a few minutes.
