Quizplus · Accepted Answer

The primary function of the respiratory system is to facilitate gas exchange between the environment and body cells. This is done through breathing, in which air is taken in through the nose or mouth, travels down the respiratory tract, and enters the lungs, where oxygen is exchanged for carbon dioxide. The oxygen is then carried by the blood to the body's cells and tissues, where it is used for various metabolic processes, while the carbon dioxide is carried back to the lungs to be exhaled.
