This video offers an overview of the process of ventilation perfusion matching, using beautiful, scientifically accurate 3D visualization and digital storytelling. We take a look inside the human body to follow the path of air breathed in, right down to the alveolar capillaries, to see what occurs to the partial pressure oxygen (PO2) and the partial pressure of carbon dioxide (PCO2) when ventilation is low or high relative to perfusion.

• This video is designed to facilitate your understanding of this specific area of respiratory physiology.
• The video and associated questions were produced with intellectual input from Professor Lewis Adams, respiratory physiologist at Griffith University, Gold Coast, Australia.
• We welcome your feedback and suggestions for future topics you would like to see 3Dme produce.
