Which of the following is true about ventilation and perfusion in alveoli in an erect posture
Apical alveoli have low ventilation and perfusion per unit volume of the lung, whereas the basal alveoli have high ventilation and perfusion.
Ventilation-perfusion ratio and the PaO2 is maximum at the apex. PCO2 is maximum at the base.
Ventilation/perfusion ratio is maximum at apex
Ventilation/perfusion ratio is maximum at base
Ventilation is maximum at apex
Perfusion is maximum at apex
