Why does alveolar air have less O₂ compared with inhaled air? A) Reduced surface tension in the alveoli leads to reduced O₂concentration in the alveolar air. B) The air turbulence in the nasal conchae dissipates most O₂from inhaled air. C) The O₂ concentration in the atmosphere is less than CO₂ concentration_. D) Alveolar air is humidified and, therefore, has more water vapor and less O₂. E) Alveolar air is the air in the anatomical dead space that does not participate in the gas exchange.
