What are the major processes of the respiratory system?

Answer: The respiratory system is what allows us to breathe and exchange carbon dioxide for oxygen. The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration.
