The Respiratory System is important because it allows you to breath.

First the air you breath in goes through your mouth and down the Trachea. After the air goes through the Trachea it goes down the bronchi which splits into two sections for the air can go through to the two lobes. Next it goes to the bronchial tubes which are the millions of little tubes in the lungs. Next the diaphragm which is the muscle that detracts and attracts. And then when it detracts the air turns into carbon dioxide which occurs when the water in the air turns and then the carbon dioxide goes through all the parts again.
