    Answer and Explanation: The nose and nasal cavity constitute the main external opening of the respiratory system. They represent the entryway to the respiratory tract - a passage through the body which air uses for travel in order to reach the lungs. Then the lungs contain the air, transfer it into the heart, and then release the CO2 released by the heart out into the air again.
