Gas Exchange Between Alveolar Spaces and Capillaries. The function of the respiratory system is to exchange two gases: oxygen and carbon dioxide. The exchange takes place in the millions of alveoli in the lungs and the capillaries that envelop them. As shown below, inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli.
Respiratory System. The respiratory system performs exchange between gases. The molecules of oxygen and carbon dioxide are exchanges, this process changes oxygen to carbon dioxide. Our respiratory system is responsible to clean out the bacteria or dust we breath in.Every living organism has that system, but in different shape and form, like how some have lungs while others have gills.espiratory System.
