Respiratory System

The Respiratory system is very important because if you did not have it you would suffocate. The diaphragm is a sheet of muscle in between the lungs and the stomach. the oxygen starts by going through the mouth and nose, the goes through the nasal passage the it begins. after going through the nasal passage it goes through the trachea. Next it is passed into the bronchi witch brings it deeper into the lungs. After the bronchi comes the bronchiole were it is brought even deeper into the lungs. At the end of the bronchioles is alveoli and connected to the capillaries. Capillaries filter out the carbon dioxide in the blood and goes through the parts then we exhale.
