Assume: relative humidity of 17.6%, temperature 23C, pressure 1 atm, P_N2 = 597, P_O2 = 159mmHg, P_CO2 = 0.3mmHg. Reaction/exchange rates of CO2 and O2 in the alveoli must be included. Given that the inhalation and exhalation times are different, calculate the rate of important gases during the inhalation and exhalation process.
