Quizplus · Accepted Answer

Oxygen is transported across the lung membrane by passive diffusion, moving from an area of high concentration (the air in the lungs) to an area of low concentration (the blood in the capillaries surrounding the alveoli). No energy or carrier molecules are required for this process.
