An аrtificiаl envirоnment is creаted where the atmоspheric pressures are as fоllows: O2: 180 mm/hg; CO2: 100 mm/hg. In the artificial atmosphere, the researcher creates three lung models, and the alveoli contain the following partial pressures: Lung X: O2: 120 mm/Hg, CO2: 100 mm/Hg; Lung Y: O2: 180 mm/Hg, CO2: 130 mm/Hg; Lung Z: O2: 80 mm/Hg, CO2: 120 mm/Hg. Which lung or lungs would have NO CO2 diffusion into the atmosphere?
