Caption: The upper image is a colorized CT scan showing different airways in the lung of a monitor lizard. The bottom image shows how air flows in a mostly one-way loop through the lizard's lung, as measured by sensors implanted as part of a University of Utah study. Note how the air flows through adjacent lateral airways (blue and purple) by moving through perforations in the airways' walls.
