Final answer:
The process of gas exchange that takes place in the lung alveoli is called pulmonary gas exchange.
Step-by-step explanation:
The process of gas exchange that takes place in the lung alveoli is called pulmonary gas exchange. Alveoli are clusters of tiny air sacs in the lungs where oxygen from inhaled air diffuses into the blood and carbon dioxide from the blood diffuses into the alveoli. This exchange occurs across the thin-walled pulmonary capillaries that surround the alveoli.
