Respiratory - External Respiration: Ventilation Perfusion Coupling

Respiratory - External Respiration: Ventilation Perfusion Coupling

Explore the intricacies of external respiration, focusing on ventilation perfusion coupling in this comprehensive lecture. Delve into the mechanics of breathing as Professor Zach Murphy explains the relationship between ventilation and perfusion in different regions of the lungs. Learn how ventilation increases from the apex to the base of the lung, while perfusion increases even more significantly, resulting in a decreasing ventilation-perfusion ratio towards the base. Gain valuable insights into respiratory physiology and understand the importance of this coupling mechanism for efficient gas exchange in the lungs.
