Question

Quizplus · Accepted Answer

The alveoli are the functional units of the lung where gas exchange occurs between the air and the bloodstream. The bronchioles and capillaries are important structures for the movement and distribution of air and blood, respectively, but they are not the primary site of gas exchange. The pleura is a membrane that lines the lungs and chest cavity but does not play a direct role in gas exchange.
