Topic: respiratory system.
The respiratory system is made up of
the organs and other
parts that control breathing. Its most important job is to bring oxygen into
your body and get rid of carbon dioxide. But, your respiratory system also helps
you make noises. When you breathe, air moves over your vocal cords and causes
them to vibrate.
Breath in: you fill your lungs with air because you need oxigen.
Breath out: you blow carbonic dioxide.
