Which process regularly exposes a respiratory membrane to maximum O₂ and minimum CO₂?

Question

Quizplus · Accepted Answer

Ventilation is the process of breathing, which involves the intake of oxygen-rich air and the removal of carbon dioxide-rich air. During inhalation, the respiratory membrane is exposed to maximum oxygen saturation (O₂), while during exhalation, the respiratory membrane is exposed to minimum oxygen saturation (CO₂). Thus, ventilation is the process that regularly exposes the respiratory membrane to maximum and minimum oxygen saturation levels. Option A, perfusion, refers to the blood flow through the respiratory membrane, while option B, diffusion, refers to the movement of gases across the respiratory membrane. Option C, respiration, is a broader term that includes both ventilation and gas exchange (perfusion and diffusion) in the lungs. Option E, exhalation, only refers to the expulsion of air from the lungs, not the exposure of the respiratory membrane to different levels of gas saturation.
