"The human respiratory system is responsible for supplying the body with oxygen and getting rid of carbon dioxide. It includes several key organs, such as the lungs, the trachea, and the diaphragm. After air travels down the trachea, it splits into two main bronchi, each leading to a lung, where oxygen is exchanged for carbon dioxide in tiny air sacs called alveoli. The diaphragm helps in this process by contracting and relaxing to change the pressure in the chest cavity, allowing us to breathe in and out."
"The human respiratory system is responsible for supplying the body with oxygen and getting rid of carbon dioxide. It includes several key organs, such as the lungs, the trachea, and the diaphragm. Air enters through the nose or mouth, travels down the trachea before it fills the lungs, where oxygen is exchanged for carbon dioxide in tiny air sacs called alveoli. The diaphragm helps in this process by contracting and relaxing to change the pressure in the chest cavity, allowing us to breathe in and out."
Please add a part about the bronchi in this paragraph. Ensure it stays below 1-2 sentences.
