claim: If Senator Wong was really serious about her  science she would stop breathing because you inhale air that's got 385  parts per million carbon dioxide in it
evidence: Similarly, since the blood arriving in the alveolar capillaries has a partial pressure of CO2 of also about 6 kPa ( 45 mmHg ), whereas that of the alveolar air is 5.3 kPa ( 40 mmHg ), there is a net movement of carbon dioxide out of the capillaries into the alveoli.
