Once you breathe in oxygen through your nose, it travels through the trachea, then to the bronchi. The bronchi helps to get oxygen to your lungs. After the air passes through the bronchi, it travels through the bronchioles which are smaller tubes than the bronchi which are bigger tubes than the bronchioles. From the bronchioles air goes to the alveoli. Then it travels back out through the bronchioles, then through the bronchi until the carbon dioxide waste is out of your system. Hope i helped :)
