Quizplus · Accepted Answer

The respiratory system is responsible for the exchange of gases, primarily oxygen and carbon dioxide, between the body and the environment. Oxygen is taken in and circulated by the circulatory system to cells throughout the body, where it is used in cellular respiration to produce energy. Carbon dioxide, a waste product of this process, is carried by the circulatory system back to the lungs to be removed from the body through exhalation.
