Question

What is the mechanism of gas exchange between alveoli and pulmonary capillaries? Compare the gas pressures in the pulmonary capillaries to the gas pressures in the alveoli in a normal person at rest. (4pts) A young woman is snorkeling and (as an observant physiology student), you understand that she must increase her tidal volume and/or her breathing frequency to maintain her alveolar ventilation rate. Why? (2pts) Briefly describe how the respiratory membrane works. What cell types and what forces allow the diffusion of gases across the respiratory membrane?

Step 1

The mechanism of gas exchange between alveoli and pulmonary capillaries is diffusion. Oxygen diffuses from the alveoli into the pulmonary capillaries, while carbon dioxide diffuses from the pulmonary capillaries into the alveoli. Show more…
