Factors affecting diffusion rate partial presure difference △ P solubility of gas S area available for dissusion A temperrature T distance to diffuse(thickness of the diffusion barrier) d molecular weight of gas MW △ P T A S D∝ d √MW The partial pressure of respiratory gases at different parts of the body Gas Exchanges in the Lung The exchange of gases in the lung between the inspired air and the blood is governed by several important physiological mechanisms. In an ideal cardiorespiratory system, perfect equilibration between the air and the blood might be expected. This would provide optimal efficiency in gas exchange. Unfortunately , the lung i
