Your lungs are the most important organs of the respiratory
system. They are situated in the chest cavity. They sit on the
diaphragm.
When we breathe, air is taken in through the mouth and
nose and travels down the throat into the windpipe.
Air is taken into the lungs through two large tubes called
bronchi. One bronchus is connected to the left lung and one
is connected to the right lung.
The left lung is smaller to make room for the heart.
When oxygen –rich air reaches your lungs, oxygen is
absorbed into the blood through tiny blood vessels. Then,
the oxygen is taken to different parts of your body along the
circulatory system.

your body in the air you exhale through your nose and
mouth.
