Quizplus · Accepted Answer

The exchange of gases (O₂ and CO₂) between the body cells and the environment occurs during external respiration, which is the entire sequence of events involved in the exchange of gases between the external environment and the body's internal environment, including ventilation (movement of air in and out of the lungs) and breathing (inhalation and exhalation). Internal respiration involves the exchange of gases between the blood and tissues within the body.
