10. How does Dalton's law apply to respiratory physiology? A. The partial pressure of oxygen and carbon dioxide predict movement of gas B. Intra-alveolar pressure must change for gas to flow into or out of the lungs C. Solubility determines the diffusion of oxygen and carbon dioxide D. The unloading of carbon dioxide determines the loading of oxygen
