This black and white line illustration, created with Dr. Peter Scrivani of Cornell University, depicts the fractal organization of the canine lungs, an important concept to understand when interpreting computed tomography (CT) scans. The artwork visualizes lung lobes divided into bronchopulmonary segments, which contain several secondary pulmonary lobules.
The secondary pulmonary lobules contain several pulmonary acini. Further breakdown of the pulmonary acinus reveals several primary lung lobules, which are made up of multiple alveoli.
