Ventilation - Drawing of atmospheric air into the lungs and releasing CO2-rich alveolar air outside
Cellular respiration - Utilisation of O2 by the cells for anabolic reactions

Spirometer - Used for measuring the volume of air involved in breathing
Cellular respiration is the utilisation of O2 by the cells for catabolic reactions (not anabolic).
