Your respiratory system is important because it allows you to breathe.

first, the air goes down your mouth and into your trachea. Next, the oxygen goes through your bronchoiles. The bronchoiles is millions of little tubes. Then it goes in the lungs into your bronchoiles. It has carrying tubes. It will go through your bronchi, and the bronchi make the oxygen go further down into the lungs. And then it will go in the Diaphragm. When you breathe in the Diaphragm it contracts. Then last, you will breathe out.
