How does air flow through the respiratory system?
The air that we breathe in enters the nose or mouth, flows through the throat (pharynx) and voice box (larynx) and enters the windpipe (trachea). The trachea divides into two hollow tubes called bronchi. The medical term for all the air tubes from the nose and mouth down to the bronchioles is ‘the respiratory tract’.
How the respiratory system works step by step?
The trachea branches into two bronchi, tubes that lead to the lungs. Once in the lungs, oxygen is moved into the bloodstream. Blood carries the oxygen through the body to where it is needed. Red blood cells collect carbon dioxide from the body’s cells and transports it back to the lungs.
What pathway does air travel through the respiratory system quizlet?

How does the respiratory system function?
The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body.
