Which of the following statements regarding ventilation is true? Following forceful echalation, an individual has completely emptied their lungs of air. O Tidal ventilation is inefficient (compared to methods of ventilation used in other vertebrates) due to the presence of dead space and the mixing of "oxygenated" with "deaxygenated" air within the alveoli During inhalation, pressure in the alveoli is During exhalation, pressure in the alveoli is lower than atmospheríc pressure. Hyperventilation results in a reduced PA02 (alveolar partial pressure of axygen) higher than atmospheríc pressure.

Explanation / Answer

Option B is is true i.e. tidal ventilation is inefficient due to dead space.

Forcful exhalation does not empty lungs completely.

During inspiration pressure in alveoli lower than that of atmospheric pressure.

During exhalation pressure in alveoli higher than that of atmospheric pressure.

Hyperventilation lead to reduced in pco2.
