The main function of the respiratory system is breathing, a process that is also referred to as respiration. This

process allows the body to bring in <u>oxygen</u> and expel (get rid of) carbon dioxide. During respiration, oxygen travels

through the bloodstream and carbon dioxide is carried away.
