RESPIRATORY SYSTEM
We need to breathe to live.
The system that helps us breathe is called the Respiratory system. So, let us
know how our respiratory system works.
First, the air goes into your nose
and enters your lungs through a pipe called wind pipe or trachea. Next, it goes into 2
pipes called the bronchi. Then, from the bronchi it goes to even
smaller tubes called the bronchioles that
are inside your lungs. After that, the
bronchioles pass the air to the alveoli which
take only the oxygen from the air. Finally,
the alveoli pass the oxygen to the capillaries,
which give the oxygen to the whole body through your blood.
Underlining new and interesting words is a good practice Tushita.
